thank you Jackie, it workish, it does not give any error, it founds that
there is a raster but nothing is displayed if used in a map.
I will keep investigating.

[mapguide-users] Configuration for PostGIS raster

[Gabriele Monfardini]

Hi, all,

we're exploring the feasibility of consuming PostGIS raster from MapGuide.
According to https://trac.osgeo.org/mapguide/wiki/MGOSGdalProviderFor26And30
it should be feasible.
However I cannot find any proper documentation on how to setup
FeatureSource and LayerDefinition.
In particular OSGEO.Gdal provider accepts some parameters, for instance
DefaultRasterFileLocation for file rasters.
I cannot find a list of accepted parameters, and how to define a source for
a PostGIS Raster.
Is there any documentation or may anyone point me at relevant source code?
Regards,

Gabriele Monfardini

Re: [mapguide-users] MapGuide (actually FDO) 64-bit Linux blockers

[Gabriele Monfardini]

Dear Jackie,

we do care about MapGuide on 64-bit Linux.
We have some of them, even in production.

But we just use FDO OGR provider, with gdal compiled with PostgreSQL
support.
We're not using PostgreSQL provider since it need a connection per schema
instead of a connection per db.
We would need many more database connections and to create a lot of
datasources, which is not at all convenient for us.

Anyway we support your effort on this, and thank you for your work!

Best regards,

Gabriele Monfardini

Re: [mapguide-users] Future plans/roadmap for MapGuide Open Source

[Gabriele Monfardini]

Hi,

we're using Centos 6 MapGuide 32 and 64bit.
But I agree it's better to focus in a well supported linux build (and
remove 64bit blockers), no problems on which modern distribution is used.

Building from source was historically a cumbersome and very slow task,
since source is very big due to the huge amount of third party libs/apps
and hard coded values in makefiles, that prevent the process to be
streamlined.
I don't know if something has changed recently in this regard.

A dream as a Linux user would be to swap out third party components and
user system defaults, shipping only configuration details (f.i. Apache,
PHP).
This would make also compiling from source much easier and quicker.

we're currently running maguide 3.0 on centos 6 both 32 and 64 bits.
We use OGR Provider with PostgreSQL 9.4/9.5/9.6.
We have recompiled libgdal to enable postgresql support.

Re: [mapguide-users] FDO Postgis provider and schema override

I had never problems with foreign keys


in my test xml schema if a table contains references to other tables there
are references to those classes.
If you make a FeatureSource for this table, do you include the referenced
tables definition in the config.xml or do you omit the foreign key? I think
tertium non datur.

Or maybe I don't understand correctly your setup.
Do you create a FeatureSource for each table, with a config.xml that
describe only that table and optionally override it in order to specify the
attribute to use as primary key? Am I correct?

I add new tables via FDO, so the SetResource purges the schema mapping.

In addition to that we restart the MG server every night.

At every new MapGuide session I test the used datasources if there is a

config.xml, if not I create it.

ok


What about repository size having hundreds of feature sources for db?

out of scope, but yes.
Its performance is quite good.


Did you optimize the MG serverconfig.ini?

Reasonably yes.


In my current setup I have a FeatureSource for each database, so I think I
can use schema override in a similar setup (one FS for database), but
apparently XML seems so long that Mapguide have problems using it.

Thank you for your answer.

What about foreign keys in your setup, you have to ignore them in the XML
schema

What about schema change, for instance when you create some new table? You
need to launch a script to create the appropriate feature sources

Re: [mapguide-users] FDO Postgis provider and schema override

[Gabriele Monfardini]

Thank you for your reply.

It takes a lot of time, but GETSCHEMAMAPPING outputs xml schema, and it is
quite long.

However if I add the xml as a configuration file to the feature source,
validation of the feature source takes a lot of time (tens of minutes).
Apparently it founds an error in the XML (the error log says there is a
mismatch between the identitiy property and the reverse identity property
of a foreign key) and recheck the feature source over and over for each
layer of the map.

I cannot even say if schema override works, since the first time the map is
opened it takes ages, apparently doing the same checks on the feature
source.

Gabriele Monfardini

[mapguide-users] FDO Postgis provider and materialized views

[Gabriele Monfardini]

Hi all,

we're using FDO Postgis provider in Mapguide open source.
In particular FDO 3.8.
It seems that materialized views are not (yet) supported.

We can workaround the problem creating a regular view that selects all data
from the materialized views but then FDO is unable to find a primary key
and in general to retrieve information about constraints.

Unfortunately AFAIK materialized views are not exposed through
information_schema since they are not exactly part of SQL standard.

They may be found selecting data from pg_class where relkind='m'.
This obviously is postgresql specific.

Is there any plan to support materialized views in PostGIS FDO?

Gabriele Monfardini

[mapguide-users] FDO Postgis provider and schema override

[Gabriele Monfardini]

Hi all,

I'm using Mapguide with PostgreSQL 9.5 / Postgis 2.2
We're comparing our current setup (OGRProvider with a recompiled gdal
library) with using Postgis provider.
The problem with our current setup is that when cache is cold it does
basically a query for each attribute in each table in the feature source
and this takes a lot of time except for small databases.

In that regards, PostGIS provider is a lot less dumb, aggregates multiple
request in a single query and only for needed tables.

But we're having troubles in selecting elements from views.
If the view is made from a single table that have a primary key, all works,
the view is seen as selectable because the pk may be used also for the view

If view definition involves some joins, even if it has an attribute that by
construction may be used as a primary key, FDO is not able to recognize it.

I've found an interesting old post about FDO schema override,
http://themapguyde.blogspot.it/2010/08/using-fdo-schema-overrides.html

This is exactly what we need, because in many case it is very difficult to
find an attribute that may be used as pk in a view without making a lot of
queries, but view creator knows which attribute should be used to identify
each row.

The problems I've found are the following:

   - FDO toolbox is unable to dump schema definition in XML. It keep
   finding errors, such as not finding element in collections. Postgresql is
   too new?
   - I was not able to find any XML schema definition file grammar, in
   order to manually construct and validate the XML override file.

Is there an XSD for XML schema definition?

 How to use OGR Provider to connect to Oracle base.



Is it indeed possible to use OGR Provider to connect to Oracle Base, but as
said by Riccardo Pucci, you need to recompile gdal/ogr library with oracle
support.
FDO libOGR provider links against libgdal found in FDO-x.x.x/lib. So you
can recompile it using the same maior version and enabling oracle support.

[mapguide-users] Requested image has wrong dimensions in Mapguide 2.5.2 with Nokia Lumia

[Gabriele Monfardini]

Hi all,

tomorrow in a Mapguide 2.5.2 I've noticed a strange error in the log.

Error: Out of range.
The requested image size exceeds the maximum.

thrown in line 362 file ServerRenderingService.cpp

Looking at the code it seems that total number of pixels of the requested
image is over 2**28 (16kx16k).

And indeed the requested image
has SETDISPLAYWIDTH=28798SETDISPLAYHEIGHT=11018

This request come from a Nokia Lumia 610 which has a 800x480 display and
IE9.

One possible explanation is that the user is manually changing request
parameters but I deem not very likely.
The other is that there is a bug in detecting the size of map image in this
particular situation.

Has anyone ever experienced such a problem?

[mapguide-users] FDO Expression Filter on current date

Hi all,

I was wondering if it is feasible to have a filter that stylize a layer

undocumented.

Re: [mapguide-users] FDO Expression Filter on current date

Hi James,



 What kind of values are in in your column? Are they actual timestamps like
 in a DateTime field, or are they strings with just years like “2005”,
 “2007”, etc? This will effect what kinds of functions you’ll need to use to
 convert the data.



column type is under my full control, actually is a string with the year
but I can transform it in Date.

However my question is about FDO function to evaluate current year, such as
CurrentDate() or something like that.
And as bonus point, also which is the function to extract the year from a
date.

Re: [mapguide-users] Unavailable SQL Server hangs-up MapGuide Server

[Gabriele Monfardini]

Hi all,


on a side note I can confirm that the same problem also happens with OGR
Provider (we're using it to connect to PostgreSQL).

If a map is accessed with a layer that uses a non reachable PostgreSQL
(f.i. a development instance), server stops responding for a lot of time
also to other requests that belong to maps that do not reference the
problematic database.
It seems that MapGuide on the whole is waiting for timeout to expire before
serving other requests.

For a quick solution the only way is to restart MapGuide, which is
obviously problematic as expires live sessions.
I have not played with customized timeout but IMHO it seems a bug.

 just a front end change so I can't see how this would affect Mapguide.
 Could something have gone wrong if it was trying to do something when I
 switched the service off?  Is there any way back from this as I don't have
 a
 backup?


Has Mapguide service shut down properly or killed?

Mapguide resources are kept in a couple of BerkeleyDB dbxml

First of all I suggest you to backup MgLibraryResourceContents.dbxml and
MgLibraryResourceHeaders.dbxml (the directory is
mapguide\server\Repositories\Libraries) and put original copies in a safe
place.
In this way if something go wrong trying to recover, you can restart from
original files.

Then you can try to use BerkeleyDB utilities inside directory
mapguide\server\bin (from a dos prompt)

Sometimes dumping the content and reloading the dbxml file solves the
problem.

db_dump -f content MgLibraryResourceContents.dbxml
db_load -f content MgLibraryResourceContents_new.dbxml

The obtained file is usually a bit smaller than original one.

You can try to put this new file MgLibraryResourceContents_new.dbxml
in mapguide\server\Repositories\Libraries renaming it
to MgLibraryResourceContents.dbxml and see if server starts.
If it starts, be sure to double check that the repository contains all the
resources (layers, maps and so on)

If this does not resolve you can try to use db_recover utility (you need
also to copy all log.00xxx files in the directory where you put the
dbxml to be recovered) and try to start with the recovered version.
Again, if it starts, be sure to double check that the repository contains
all the resources.

You can find the documentation (even if mapguide version od berkeleydb is
older) at:

http://docs.oracle.com/cd/E17276_01/html/api_reference/C/db_dump.html
http://docs.oracle.com/cd/E17276_01/html/api_reference/C/db_load.html

[mapguide-users] Suspend and automatically resume digitizing in Ajax Viewer if user performs map actions

[Gabriele Monfardini]

Hi all,

I'm using Mapguide 2.5.2 and Ajax Viewer.

Currently when a user is digitizing and want to zoom or pan,
digitization is ended. It would be useful to automatically re-enter
digitization and let the user end its work.

This can be done simply tracking previous digitization state and
cursor along with current digitization state, and modifying some
functions in ajaxmapppane.templ.

We've providing this functionality in our deployed MapGuide, and I
think it would be useful to others.

I opened ticket https://trac.osgeo.org/mapguide/ticket/2395, providing
an untested patch to implement this enhancement.

Can you please revise it and share your thought?

Re: [mapguide-users] Legend Pane Size - Chrome

[Gabriele Monfardini]

Hi all,

a collegue of mine found a workaround for this Chrome strange behaviour,
adding two lines in function LayoutControl() of ajaxmappane.templ

if(isProperties)
lh = legendHeight;
else
lh = wh - y;
legendCtrl.style.height = lh + px;
legendCtrlDiv.style.height = lh + px;

+ legendCtrlDiv.style.width = infoWidth + px;
+ legendCtrl.style.width = (infoWidth-1) + px;

if(infoWidth = 20)
legendCtrlDiv.style.visibility = visible;
y += lh;

Please confirm that the workaround works (we have a somewhat customized
setup) and then I'll open a bug and propose that as a workaround

Re: [mapguide-users] Legend Pane Size - Chrome

[Gabriele Monfardini]

Hi Greg,


I have changed the legend size variable in the ajaxmappane.templ  file. With

Firefox and IE it works as expected.  In the latest version of Chrome the
 legend size is changed but the legend itself does not expand to fill the
 space.  See the image:
 http://osgeo-org.1560.x6.nabble.com/file/n5086196/temp.jpg

 Has anyone else noticed this?


if you start resizing the frame, the legend frame redraw and this time your
settings are honored.
This bug does not appear in Chrome 28, while it is present in Chrome 29 and
30 (in all OS, and also in beta version).

In my opinion something goes wrong in initialization, since legend panel
height is initially set to 200px even if you disable property pane.

I think this deserves a bug to be opened, I'm trying to find a workaround.

So, rewriting more precisely my question, the fact that libFdoPostgreSQL.so

Re: [mapguide-users] How many of you are still on 2.2 or older?

[Gabriele Monfardini]

I have some MapGuide 2.2.

The reasons are the followings:

  * I use an unusual setup: Linux (centos), PostgreSQL (using OGR
Provider).
My installation of MapGuide 2.2 are under centos 5, while the our Mapguide
2.4 are under centos 6.
It takes some time to migrate from Mapguide 2.2 to Mapguide 2.4
  * Most importantly, I have a strange annoying bug in MapGuide 2.4 that

When it happens, sometimes one thread remains stuck at 100% CPU and
mapguide stop serving at all (but does not crash).
Every new request end up logging the very same error.

The error message is somewhat misleading.
The server has 4GB RAM and never use more than a couple of it.
We've configured the max allowable sessions to a much higher value
than the default and, in any case, the number of active session when
it lastly happened is about 20.

Am I reaching some memory limit on session dbxmls?
Maybe something related to pages or caching?
Would you suggest to tune some parameters in serverconfig.ini?

Re: [mapguide-users] Fusion broken.

[Gabriele Monfardini]

Hi,

 I don't know. I'm just using the default install of 2.4.0 and expected it
 all to work.

 Running a search, there don't appear to be any MapDefinition files
 anywhere in the entire /MapGuide directory.
 I'm surprised no samples were provided in the default install.

Map and layerdefinition are on a single-file db (a dbxml).
Try downloading Mapguide Maestro, and log in on the server (substitute
localhost with the name or the IP address of Mapguide) with default
account (Username: Administrator, password: admin).

If it works you'll see a on the left a tree, called Library which
contains folder Samples and inside the map definition you're looking
for.
In particular

Library://Samples/Sheboygan/MapsTiled/SheboyganSphericalMerc.MapDefinition

means that it is trying to load SheboyganSphericalMerc.MapDefinition
inside Samples/Sheboygan/MapsTiled.

 Looking into the documentation it's not clear how to make a MapDefinition
 file (the search only finds two results which make reference to them:
 http://mapguide.osgeo.org/search/node/mapdefinition), and the samples I can
 find are for 2.0.x
 (http://mapguide.osgeo.org/download/releases/2.0.x-samples) with the
 installation notes not appearing to work with 2.4.x.


Mapdefinitions are xml files with a precise schema.
Mapguide Maestro is the tool that ease creation of all xml files you need.

Mapguide Maestro allows you to create FeatureSources aka connection
to data, LayerDefinitions (aka layers that use data), MapDefinitions
(aka collections of layers) and WebLayouts (aka a presentations of a
map).

Re: [mapguide-users] Refresh Layer Properties in Maestro

[Gabriele Monfardini]

 Using Maestro (I'm using 4.0.3), is it possible to refresh the Layer
 Properties (feature class) of a layer without having to remove the layer and
 add it again?
 I have an issue where a database has changed over time. I can remove and add
 the feature source to refresh the feature classes (getting new tables in the
 list), but the task to refresh the layer properties is painful.

You may try to purge cached schema information.
It will force Maestro to examine again the schema of the db and it
will find schema changes.

After that, if I undestand correctly your issue, reopening the layer
should show you current properties.

Re: [mapguide-users] Refresh Layer Properties in Maestro

[Gabriele Monfardini]

 Purging the cache did not help. The two new fields in my table does not
 appear. If I add the layer over again they do.
 I am using MapGuide OpenSource 2.2 and KingOracle provider.

The PropertyDefinitions are saved in the xml, but they only map the
Name with the Display Name.
So if you mapped a property that now has disappeared it remains in the
xml (causing obscure-but-innocuous FDO errors, like
FDO_81_IDENTIFIER_NOT_FOUND).
At least this is what happened some version ago.

But the xml does not contains all properties of a layer, that are
retrieved a runtime (using caching schema information).
If you close and reopen the layer after purging schema info the new
properties should appear in the list of the properties.

This is my test.

* Open the layer definition in Normal (non-xml) mode
* Look at Layer Propetries Visible in Viewer panel: it shows the
properties of the layer, e.g. p1, p2, p3
* Add in the db the column test_column at the table referenced by
the layer definition
* Close layer definition
* Reopen layer definition: test_column is not there (it is using
cached schema information!)
* Close layer definition
* Purge cached schema information for the correct feature source
(using right-button menu on the layer in the Site Explorer on the
left)
* Reopen layer definition: test_column has appeared in the pane.

Is it the same for you?

That said, we need some info if you wan't suggestions.

For instance, which was the pScale? Which was the final scale you obtained?
Have you a base layer in your map (which has fixed scales)?

Probably you don't need to call the function Refresh after calling
zoomToView since you are calling function zoomToView with value true
for the parameter refresh.
Maybe the extra Refresh is interfering with the previous zoomToView?

Re: [mapguide-users] MGOS 2.2 - WMS problems with Meastro

[Gabriele Monfardini]

Hi,


 No luck loading the ArcServer WMS into a new MG 2.4 installation, same
 error. The Service Loads fine in Arcmap, ArcGIS.com, and Google. I have a
 feeling its an issue with projection. If you can have a look at the Getcap
 info. Perhaps when you get a chance you could run it through your system to
 acquire the WMS.

 Here are my parameters coming from ArcServer;

 http://www.geomapix.com/lgswebadaptor/services/BaMosaic2/ImageServer/WMSServer?request=GetCapabilitiesservice=WMS

I've made some test (I'm interested in trying to setup Mapguide to consume WMS).
I have mapguide 2.4 on centos.

First of all, I've tried to load the layer under a fairly good WMS
client, a recent version of QGIS.
All works, even if the layer is quite heavy (at higher scales, it
downloads over 1MB each time).

Under maestro (compiled from source some days ago), I'm able to setup
the Feature Source. Testing connection does not show any error (the
URL used is  
http://www.geomapix.com/lgswebadaptor/services/BaMosaic2/ImageServer/WMSServer?;
I'm also able to create a layer over it.

It automatically fill the Feature Source field of the layer with
WMS_Schema:_x30-, and the Geometry Property with Raster.

And here stops the good news.
In fact previewing the layer or previewing a map with only this layer
end up in the following error:

2012-08-24T18:54:59   -1463587984 MapGuide Maestro v5.0.0.6640

Error occurred in Feature Source

So, better luck than you but does not work out of the box.
Maybe the _x30- is related to something you can control on WMS Server side?

They're not plain text files but entries in a dbxml file.
They can be accessed through Maestro or with dbxml C API.
Otherwise you can use dbxml utilities shipped with Mapguide (db_dump,

Interacting through Maestro is by far the simplest and quickest way

Obviously if you can afford it, it would probably be better for you to
wait for mapguide 2.4 with gdal 1.9.

Re: [mapguide-users] What is the best system specification for MG2.2 with 90ish layers?

[Gabriele Monfardini]

 Layers: 80ish (.shp, .tiff, Access database, SQL Express 2008)

I think they are far too many.
You will have slow map startup (even if most of them are not shown at
startup, because of some per-layer overhead), and a very huge legend,
that is probably a bit overwhelming for your users.

I'm not saying that MGOS will be slow whichever resources you throw at
it (it most depends on your data), it may results perfectly viable (or
it may not).

But I don't consider having a map that display so much layers a good approach.

Moreover, you may want (if it is possible) to prepare your data.
Using a database with a spatial index is the best solution, since your
performance quickly become I/O bounded if you have huge tiff raster
and shapefiles.

You may consider loading shapefiles into a spatial layer of your db
(though I'm not sure if and how you can do it in SQL Express), and
loading Access data in SQL Express (and maybe connect data from MS
Access if you need to access it from an external application). MS
Access is not exactly tuned for performance, and you lack spatial
indices.

If you experience low performances and low CPU/memory load you may
consider to move the db to another tier to mitigate I/O load.
My 2 cents.

If this is the case, set longer session time in serverconfig.ini.

Has the server been restarted (or is crashed and automatically restarted)?
If this is the case you should try to understand which is the problem.
Verify that error log does not show any other issue with you layers and maps.

Re: [mapguide-users] Re: MapGuide 2.4 Beta?

[Gabriele Monfardini]

Hi Jackie,

 Ah yes, the dreaded linux question :)
Lol. I also was afraid to ask :)

 Well fortunately this time round, my gcc/make/ld error comprehension skills
 have improved significantly from my last major attempt and as a result, I've
 had some successes building mapguide on ubuntu (11.10)*

Good.

If I remember from some early attempts I've made in the past, some of
the problems also stems from the very brittle and custom compilation
path.
Even in Oem software, that should compile quite out-of-the-box.

Kudos to you if you dare to make compilation under Linux a little more viable.

 So the question then becomes: What linux distros do you want to see a
 mapguide build for? Also I will readily admit to not being a full expert on
 these matters, so may need assistance

Wow, I can choose?
Linux support is getting better and better :)

Current Debian/Ubuntu is my first choice.
But also centos is fine.

The important is that a recent version is targeted.

I've seen that Autodesk IMS support RedHat Enterprise 5.5, so centos
5.5 should compile and work.
We're using MGOS with centos 5.5 and centos 6 with success (the latter
with some ugly hacks, but it works).

So choose the (reasonable) distro in which you have less trouble to compile it.

I'm also not a great expert but I'll help at my best if you report
your advancement and problems.

  2. Are you capable of using Mono 2.8 or newer? I know Ubuntu for example,

Ubuntu current version (oneiric) has 2.10.5 in their official repository

Mono currently has a lot of glitches, most of which are very annoying

Re: [mapguide-users] MapGuide 2.2 GDAL Raster Provider - a little help finding some files

[Gabriele Monfardini]

 Problem is that the file is no longer available on Tamas' site.  Does anyone
 have a copy of this file kicking around that they could send my way?
  Alternatively, can anyone confirm if a newer build would work - and be
 stable?

I'm on Linux and for some reasons I have to compile gdal myself.

I've compiled and used (in production sites) version 1.6.0, version
1.6.3 (last release in 1.6 branch if I remember correctly) and version
1.7.2, without particular problems on tiff and png rasters (even if
some care is required preparing the files, and I strongly suggest
testing the files with gdalinfo prior to deploy it).

I've also tried version 1.8 from SVN some times ago and had some
problems with mapguide. At the time I had not enough time to
investigate the reason, also because version 1.7 appered to run well.

I've compiled it passing the parameter (--with-thread), that for
versions below 1.8 is not the default, in order to have multithread
support.

So probably a correctly compiled gdal 1.6 or 1.7 for windows is going to work.

Re: [mapguide-users] Is GDAL working and Stable in 2.2?

[Gabriele Monfardini]

Hi Trevor, hi all,

one thing that would be beneficial and easy to do is using a more recent gdal.
Current stable version is 1.8 and MapGuide by default uses 1.6.

Not enough, it uses 1.6.0 while the last stable version in 1.6 branch is 1.6.3.
Usually point releases are mostly bug fixes so using 1.6.0 is not a good idea.

Another issue is that in 1.6 branch one has to manually pass
--with-thread to gdal compilation (at least in Linux one) to have
thread safe support, that is not enabled by default (while it is
enabled by default in 1.7 and in 1.8 branches if I remember
correctly).

I have to recompile gdal to enable postgis support in OGR provider
(I'm on Linux) and, as expected, version 1.6.3 works well with
MapGuide.
Moreover, also latest stable in 1.7 branch works fine, while I've had
some problem with 1.8.

In my tests I use OGR Provider with PostgreSQL/Postgis and gdal
provider with tiff and ecw images (I've kept the single connection in
gdal provider since I aim for stability, but not in OGR Provider that
would be too penalizing).

Re: [mapguide-users] Starting MapGuide Open Source 2.2 automatically on Ubuntu 9.10

 And is the only way to
 stop the MapGuide service is by killing it?

The kill command without any signal asks kindly the mapguide server to
terminate (the default signal is TERM).
Thus it is not killing it, but rather stopping it and may fail if
the process does not stop itself (and Mapguide server in my experience
sometimes fail to stop and you have indeed to properly kill it).

To forcefully kill immediately a process the syntax is kill -9
(signal KILL. It is not recommended since you may incur in data loss
or dbxml corruption).

Re: [mapguide-users] Partial transparent selection color of the Ajax viewer

 With MapGuide OS 2.1 (Enterprise 2010), PNG 8 bits and the GD render, I can
 confirm that the alpha value of the selection color does not have any
 impact.

Apparently, with PNG8 format, selection color do not have alpha value.

Since global image format and selection overlay format can be set
indipendently, a workaround is to set image format to PNG8 and
selection overlay format to plain PNG (that correctly uses alpha
channel).

Selection overlay images are usually small and simple, thus PNG images
are just a little bigger than PNG8 counterparts.

Re: [mapguide-users] Some thought on FDO PostGIS Provider

[Gabriele Monfardini]

@all
Thank you for your quick replies.

@Traian
 It never was compiled with PostGIS by default.
 Before, I was doing a custom build with a static link to an
 OGR build which has PostGIS support built in.
Ok. I was only saying that there was PostGIS support out of the box in
Windows binaries.

Needless to say that takes a long time to do due to the huge dependency list
 and there have only been one or two people who have asked for it,
 so not enough demand to make it worth my time.

Compiling GDAL with support to all takes about 30 minutes on my Linux
box, against 15 minutes if I disable all except the core.
However, I don't want to blame you if you drop some less used dependencies, but

1. PostgreSQL+PostGIS is by far one the most used in open source GIS,
much more than MySQL.
Moreover it is at the state of the art w.r.t. much more expensive
other solutions.
2. PostGIS provider doesn't always work, and it is not so well mantained.

Don't you think that it would be useful for the casual user to have
PostGIS support working well out-of-the-box?

 However, since the default build now uses dynamic link to the GDAL DLL,
 you should be able to replace the Gdal.dll with one that has PostGIS support
 compiled in it and automatically get PostGIS support.
I only have such builds for FDO 3.3 (MG 1.2), posted at 13-9.com.
 If there is enough demand, I could try to do a build with whatever FDO
 the new MGOS is using -- but it would really be better if someone else
 who is more vested in this volunteered, and I could provide some support
 with how to build it.

I've found this link.

http://n2.nabble.com/FDO-OGR-Driver-3-4-0-Connecting-to-PostGIS-8-2-with-AutoCAD-Map-3d-2010-fails-td3728628.html#a3736552

It is not perfect since you have to add 2 more dll to the list in
order to solve all dependencies, and choose the correct gdal version.

The fact that MapGuide is tied to one specific version of gdal and its
dependencies may make difficult in the future to find all the dlls in
the required versions (that moreover, AFAIK are not well documented
anywhere...)
It is one of the cons to include gdal source in mapguide instead of
building against the current stable tree.

I propose this solution, that I think is a win for all.
Add one page into FDO site that hosts all dlls needed, in the
versions-needed-for-current-Mapguide-stable-tree (TM) and a step by
step procedure (that simply says delete these dlls, add these other
ones).
If you want I can help you finding all dlls, since my setup now seems to work.

In this way you may keep compiling OGR faster without PostGIS support
but PostGIS users are no more needed to guess which particular
gdal.ddl, libpq.dll etc... are required, nor to find tricky hints into
forums.

@Jason
 but the fact is that it's languishing because it hasn't had enough community
 interest and development support.
It is surely true, but also the contrary may be true.
It hasn't had enough community interest since it has never worked well
out of the box.
I cannot promise my boss I can solve all the problems, thus it is
difficult to support Mapguide adoption in a PostGIS environment.
Let's at least make easier to use OGR that has supported PostGIS well
until several years and it is maintained independently from MapGuide

@Kenneth
I have recorded the requests as issue #1275:
Thank you very much. Let me thank you again for the time saved using
Mapguide Maestro, a very good project.

 The update layers, when featuresource changes request, is recorded as issue 
 #1067
 If there is any way you can provide reproduce able instructions for the save 
 problem,
 please let me know.
I'll do my best.
For what I've seen, the problem happens only when the FDO PostGIS
timestamp with time zone bug is triggered.
The bug cause also FdoToolbox to crash, so I'm pretty sure is a FDO bug.
When the schema is read correctly, also the save works in Maestro.
I need to do some more tests, in order to provide you a small test
that is reproducible.

Each time you start a map or something similar, MapGuide
 issues a DescribeSchema request. If you simply reference
 your entire database, this will take much longer than if you
 split it up in schema parts.
I understand the point.

 Also, if you expose your entire db, be aware that you are effectively
 exposing the database to the users. A rouge user can easily
 get MapGuide to hand over all exposed data, so the less there
 is avalible to MapGuide, the better.
I also understand this point, however PostgreSQL has access control on
all objects, it is not difficult to setup it to restrict access only
to the needed data.
This is the why all other libraries use connection to the db and not
to the schema.

 I have also built the OGR and Gdal provider with PostGIS support
 some time ago. I belive the build procedure is now so simple that
 it is just a matter of installing Visual Studio, checking out the code with
 SubVersion, and running the build.bat.
I use Windows binaries in order to have them in 

[mapguide-users] Some thought on FDO PostGIS Provider

[Gabriele Monfardini]

 I try to save the problematic dataconnection it warns me that FDO
connection failed and offers to save it anyway. Sometimes, even if I
save it, it does not record correctly the Datastore, leaving it empty
in the XML.

Last rant.
Why OGR is no more built by default with PostGIS support?
It would have provided me a much more smooth upgrade from 1.2.
Moreover, FDO PostGIS Provider is quite recent, initially developed
only for Windows, and I suspect not so much used.
Having 2 possible connection to PostGIS would offer the possibilities
to compare the performances (that in my situation are very important)
and choose the best one.

I am not so happy to drop here and there new dlls, also because in my
experience MG is quite strict on library versions, and at least
version 1.2 quite poor on logging useful information. So this could
lead to not-logged crashes or generic errors that are very difficult
to solve.

That said, if you know an URL with OGR dll compiled with PostGIS
support, in a version compatible with Mapguide, I would rather try
them, before starting editing the 1000 layers...

Re: [mapguide-users] Problem with map only half showing.

[Gabriele Monfardini]

You may try to have a look to the output of the command gdalinfo
applied to your tiff files.

It sometimes reports errors or warning, expecially on compressed tiff
files created with some applications.
This probably means that gdal have some problem reading the file even
if it appears correctly in image viewers/editors.

The most common issues, in my experience, are non conventional
headers, missing data at the end of some blocks, application specific
metatadata information. Minor things that however may confuse gdal.

We've had the same issues with some tiff files and similar results:
the layer sometimes is partially showing, sometimes completely missing
and sometimes working correctly. Even a very small pan produces a
quite different result, almost unpredictably

We recreated the tiff file, checked that gdalinfo output was positive
and that fixed the issue (however in mapguide 1.2)

Re: [mapguide-users] Problem with the dwf viewer and a reverse proxy.

[Gabriele Monfardini]

 Problem :
  The dwf viewer does not display the map, it displays all the other
 frames correctly, i.e tbFrame, taskFrame and from the mapFrame only
 the     Layers  and Properties panes. The ajax viewer works
 perfectly.
  I have noticed in the logs of the apache server that the dwf viewer
 tries to access directly the server that is behind the
                         firewall,  http://mapguideserver:8008/mapguide,
  not the alias that is configured in the proxy,
 http://mapguideexternalalias/mapguide.
     This happens only one time when the dwf viewer tries to get the map.

 Request:
   Does anyone have a solution or a hint or something that my help ?
 Thanks.


We've had the same problem.

Our solution was to modify two values inside mapguide-apache httpd.conf.

ServerName should be your mapguideexternalalias (the URL of the
apache that is configured to access mapguide via proxy)
UseCanonicalName should be On

In this way self-referencing URL will be constructed using ServerName

Re: [mapguide-users] Oracle 10g Standard

[Gabriele Monfardini]

The main problem here is that there is very few info about the correct
version of the libraries used.
This, combined with the very poor logging messages of both
FDO/Mapguide very often lead to Unspecified errors or Generic
errors when the wrong version of something is used.

And the advices often consist in dropping some dlls here and there in
order to find some unresolved symbols, which makes all things sound
like an obscure art or a per-installation magic trick.

In order for this to work reliably, we need full information regarding
Postgres/Postgis version used (yes, even the last minor number),
together with FDO and Postgis provider versions.

Postgis provider support for Linux is, at best, lacking some care. OGR
support is not enabled any more by default, AFAIK.
Yes I can enable it and compile all again but compilation is difficult
not to say too difficult.
I think OGR provider should be enabled again by default, at least
we'll have a fall-back.

Btw we're using a Mapguide 1.2 on Debian GNU/Linux with Postgis
connected through OGR Provider.
We had to work hard in order to compile all the stuffs (and this is
remarkably poor in a project that has Open Source in its name), but at
least it works.
We've not yet find a way to compile version 2.x. No significant steps
have been made to ease compilation in GNU/Linux, even if version major
number has been increased...

Gabriele Monfardini

Re: [mapguide-users] Postgis OGR provide

[Gabriele Monfardini]

We've made some investigations on this issue.

It appears that in latest precompilated Windows binaries OGR support
for Postgresql (that has to be enabled at compile time) was dropped in
favor of the new Postgis provider.
Probably this also happens in OGR provider compiled under GNU/Linux.
Error messages don't help much to understand.
Maybe you can check your OGR provider dynamic libraries with ldd to
find unresolved symbols.

Postgis provider seems to need a fairly recent version of Postgresql
header in order to work (it works in Windows against Postgresql
8.2.10, it does not against Postgresql 8.1.15)
We're trying to compile the Postgis provider under Debian etch
(stable), using newer packages from lenny (testing) when needed.

The problem is that compiling flags force build to go until the end
even if some symbols are unresolved. And this is how we've find that
the new postgis provider needs a recent postgresql version.

If you find something new please report me.

Re: [mapguide-users] what's holding people back from upgrading to 2.0?

[Gabriele Monfardini]

One big issue for me is the impossibility to use PostgreSQL+Postgis as
database solution for geographic data.

The new Postgis provider does not work (it seems to be only for
windows, and not so stable).
The old OGR Provider, that works fine in 1.2 ... does not work in
2.0.1 and in 2.0.2.

Our build from source code doesn't work, windows binaries don't work,
livecd doesn't work either.
Clearly neither MGE2008.

A long standing bug is opened (#666)
http://trac.osgeo.org/mapguide/ticket/666
but it is not receiving any feedback (maybe the bug number is unfortunate...)

Some mails to this mailing list and some questions on #mapguide and on
#fdo on IRC are still waiting for answers.

It appears that not so many Mapguide users are interested in
Postgresql+Postgis, even if, IMHO, is one of the best RDMS for
geographic data.

We've seen that Mapguide 2.x has a lot of improvement over 1.2. But,
as a matter of fact, does not support Postgresql+postgis. So we're
stuck with old 1.2 until this problem is solved.

Gabriele

[mapguide-users] Postgis OGR provider

[Gabriele Monfardini]

Hi all,

We're having problems using PostGIS and OGR provider.

We've built MGOS 2.0.1 and fdo-3.3.0 in Ubuntu 7.10 without errors,
but neither PostGIS provider, neither OGR provider works correctly.
They always throw some exceptions when I try to connect to any
PostgreSQL + PostGIS db.

Under MGOS 1.2 OGR provider works fine with the same data.

Does anyone use PostGIS with MGOS 2.0.1 and fdo-3.3.0? With which
provider? Using the binary or compiling all from the source?

[mapguide-users] Load balancing and RFC3

[Gabriele Monfardini]

I've seen that in RFC3
http://trac.osgeo.org/mapguide/wiki/MapGuideRfc3 was proposed (and
implemented in 1.2) to use a load balancing scheme that allows to have
multiple site server under one web tier.
In order to cope with sessions, each user should be served by the same
server that fulfills his/her first request and at each new client the
server is chosen in a round-robin fashion.

Does everyone have tried this?
I want to try this solution since the performances with 1 server are
quite poor (several seconds to zoom or pan in map with a few Postgis
layers), and moreover, CPU usage  goes near to 100% for 3-4 seconds at
each request. I think that with one server service time would be quite
long if there are several request together.

I've tried with version 1.2 and it doesn't work properly. Requests
from different clients are correctly dispatched to my two servers but
the server that is not in the same machine of the web tier keeps
telling that the session is expired or non valid.

I've configured webconfig.ini as in RFC3.
Am I missing something?

Re: [mapguide-users] Load balancing and RFC3

[Gabriele Monfardini]

 Are you using tiled maps?

No.

I'm not sure it will work:
http://trac.osgeo.org/mapguide/wiki/MapGuideRfc42

This RFC removes existing functionality. However, site and support servers 
were difficult to configure and it is unlikely that this functionality is 
currently in use. It will still be possible to turn off unnecessary services 
by directly editing serverconfig.ini.

If I understand correctly, the idea is to drop the division between
support servers and site servers (the former ones doing some services
for the latter ones) and to use load balancing as in RFC3, i.e. with
multiple site servers, each one with its clients.
In RFC42 it is written correctly that this will increase robustness
since with support servers if one server fails the same does the
entire site since some services are no more available (and the
failures are quite common in my tests...).
On the contrary with load balancing as in RFC3 the other site servers
can continue to serve even if one of them encounters a problem.

It seems that RFC3 have been implemented in 1.2, because in RFC3 it is
written Proposed milestone: 1.2 and Implementation Status:
completed.
And round robin seems to work, but there is some problem with sessions.

It is a pity, since multiple servers may be useful to increase
robustness (that is quite poor) and performance (that is extremely
poor w.r.t. MapGuide 6.5). Probably I should move to MapGuide OS
2.x...
