Re: [Geoserver-users] Out of memory error downloading large wfs response

[Chris Holmes]

I think an alternative would be to keep the gzip filter off and just let
your servlet container do gzipping. Or the http server in front of it if
you have one. See like
http://viralpatel.net/blogs/enable-gzip-compression-in-tomcat/

I feel like that's now the general practice on the web? That the
application shouldn't worry about it. And I think the container can be
smarter about knowing when the client supports gzip. Though perhaps it's
harder to configure for all our output formats?

Re: [Geoserver-users] Benefit of caching with WMS client

[Chris Holmes]

Afaik GeoWebCache has the ability to do this with its WMS. See
http://geowebcache.org/docs/current/services/wms.html

Ian, cced, I believe started some work to make it so the embedded GWC could
do the same tile recombination to a WMS call with one or two vendor
parameters. I'm not sure if we got it all the way back in to the core, as
the project we built it for I believe has not deployed it yet.

Note this strategy should work well for raster data, but for vector you
will likely get some fuzziness for requests between zooms.

In general getting the fastest results depends on how you prepare your
data. If you're using raster data than inner tiling and overview on
geotiffs can get you to very fast speeds. See
http://docs.geoserver.org/stable/en/user/production/data.html

Re: [Geoserver-users] Lead Data Scientist at Geospatial Startup

[Chris Holmes]

Hey JD and 'contact', unfortunately we don't allow posting of jobs directly
on the user's list.

If you have a job post that is truly relevant to GeoServer users /
developers (like I'd expect to see GeoServer called at as a specific skill,
not just geospatial), then you can get in touch with anyone who posts to
the blog with the job posting. We do periodic postings to get people aware
of opportunities related to GeoServer, like
http://blog.geoserver.org/2013/05/28/job-offer-geoserver/

But we try to keep this list free of unsolicited job postings.

thanks,

Chris

Re: [Geoserver-users] Polygons with outlines using gradients

[Chris Holmes]

You could also try to make a rendering transformation for it, see
http://docs.geoserver.org/stable/en/user/styling/sld-extensions/rendering-transform.htmlfor
a start.

So instead of storing the rings in your database you could have geoserver
create them on the fly with a WPS process that's only applied at render
time.

Re: [Geoserver-users] Allow using shapefile index if create spatial index checkbox not selected [SEC=UNCLASSIFIED]

[Chris Holmes]

Hey Geoff, thanks for taking the time to dig in to the code and figure out
what's going on. You're our favorite type of user ;)

Thinking about your two options, I can't see any situation where a user
would actually want shapefile indexes disabled. So I'd say your patch as it
stands right now makes sense - no need to add another parameter to the
datastore that lets people turn the index off. We don't have that option in
like postgis or oracle.

To get it actually in the code base, I think there's two things that can
help to get a developer to review and get it in.

First, create a pull request in github -
https://help.github.com/articles/creating-a-pull-request  Their system is
great and afaik it's easier for developers to review their then to pull in
a patch from the list.

Second, create an issue in our jira tracker at
http://jira.codehaus.org/browse/GEOS And then just in a comment there put a
link to the github pull request. You could also directly attach the patch
there if you'd like.

Some others may have input during the review process, but from where I sit
this is a nice little improvement on the codebase. Thanks for digging in
and helping!

Chris

[Geoserver-users] Advanced GeoServer Training Nov. 19 and new Training page

[Chris Holmes]

Just a quick announcement for those who haven't seen the blog post on
training - http://blog.geoserver.org/2012/11/12/geoserver-trainings/

There's a new section of the website for training, see
http://geoserver.org/display/GEOS/Training

And at OpenGeo we're putting on a web-based Advanced GeoServer
training on November 19th (next monday). See
http://geoserver.eventbrite.com for more information. Should be a
great opportunity to get more out of your GeoServer, topics include
the REST configuration API, Web Processing Service, rendering
transformations like heatmaps and barnes surface interpolation, SQL
Views and more. Please join, as interest in early trainings will help
more companies be able to put on more regular classes.

(Note that the PSC discussed a general policy for posting trainings on
the user's list, which is that it's fine as long as the training is
only about GeoServer and its extensions, as we want users to be able
to get more help, but don't want this list to be filled with tons of
training posts. If we get too many pure GeoServer training posts we'll
likely change to some sort of digest / blog posts, but for now all are
encouraged to share pure GeoServer trainings here).

Re: [Geoserver-users] ServiceException - could not find layer

Huh. Yeah, shp2pgsql should make it all properly.

Other layers imported the same way work fine? It's just that layer that
messes up?

Does serving the shapefile by itself from GeoServer work?

Re: [Geoserver-users] ServiceException - could not find layer

[Chris Holmes]

Do you have a primary key defined on your layers?

I _think_ that error is it trying to find an alternate primary key. You can
define that table if you're using views (that can't have a primary key).
But if you're just serving normal layers then defining a primary key should
work best.

Also PostGIS 1.4 is 3+ years old at this point, you may have better luck
with a more recent version.

Re: [Geoserver-users] WMS request=getcapabilities takes a loooooooooooooong time to return

[Chris Holmes]

Thanks for offering the possibility to code! We always love new
contributors to GeoServer.

I'm not sure on the classes, Andrea can help with that. But seems like it
would ideally work in the same way the 'bounds' works. It was built the way
it is for the same issue - dynamic requesting of data can slow capabilities
documents a lot.

Perhaps we could do it in the same GUI call of the bounds on the
featureType? I mean, it seems to just be an extra dimension of the bounds.
So a user would hit 'generate bounds' and it would grab not only the
geographic bounds but also the time bounds. I'm just thinking that could be
nicer than two different buttons they have to hit.

And definitely would be good to get away from that fully dynamic generation
of any part of the capabilities document, we should try our best to make it
so the default experience is always both fast and fully standards
compliant. Better to have a user be able to choose 'dynamic mode' if they
want it generated every time, and default to a cached thing that performs
better, imho.

Re: [Geoserver-users] 5 seconds to render 130, 000 points -typical GeoServer WMS performance?

[Chris Holmes]

You  might try the same layer on postgis and see how it performs. I think
Oracle doesn't perform quite as well. I believe OpenGeo has a contract
coming soon to improve the performance on Oracle, with a plan to look in to
some of these bottlenecks.

It should, though you have to be sure you've also enabled direct WMS
integration in GeoWebCache, or it'll just a small in memory tile thing in
geoserver. I think in 2.1.3 there's an option to turn it on in the
geoserver admin.

Re: [Geoserver-users] REST API layer thumbnails?

[Chris Holmes]

Well if it's useful to both of you in the context of the REST API it's
probably worth at least putting a link to the docs from somewhere in
the REST docs. Patches welcome, especially for docs (and indeed if
there's other REST stuff you've discovered and have some time to
document it'd be super welcome documentation).

We also could potentially consider a shortcut in the REST API to the
reflector, so you could use the same layer endpoint to get a
visualization. Though that probably warrants a larger conversation, as
it takes us from a REST API just for configuration to more
functionality.

Re: [Geoserver-users] To tile or not to tile

[Chris Holmes]

If you truly can't do any caching then I'd guess arbitrary maps would
perform slightly better. Less requests to the server for each view
you're looking at.

But you probably could cache tiles in your use case. Could use
parameter filters in GeoWebCache -
http://geowebcache.org/docs/current/configuration/layers/parameterfilters.html

These will make a series of caches based on whatever free parameter
you want. So you should be able to do it on your SQL parameter.
Combine that with some disk quota configuration so you end up just
caching the most requested tiles and you should have a decent cache
for the requests that are issued most often.

Re: [Geoserver-users] Which would be fastest - WMSGetFeatureInfo, or WFS DWithin Spatial filter

[Chris Holmes]

The best solution to this will be to implement UTFGrid output from
GeoServer.  See OpenLayers example at
http://tschaub.net/openlayers/examples/utfgrid.html

Will take a decent bit of development effort, as it gets in to core
rendering stuff.  But will be awesome if we build it right.

I'd guess the best place to start would be a GeoServer community
module.  See 
http://docs.geoserver.org/latest/en/developer/policies/community-modules.html

If you're willing to shepherd it and may continue to work on it then
we can probably get you approval pretty easily, and then you just get
a space on the GeoServer svn to play with.  And others would then be
able to help expand it.

If you have very little time then you could just attach it to a patch
and hope someone else might pick it up.  But an arcgis store community
module would be appreciated by many people I believe.

Re: [Geoserver-users] mbtiles support

[Chris Holmes]

Hey Steven, if you're use is just the most compact raster source then
I think a lossless compression format like mrsid / ecw / jpg2000 may
serve you a lot better. MBTiles certainly is an improvement over a
bunch of tiles on disk, as it cuts out the disk blocks.  But that's
about the only gain you get afaik, while the lossless formats actually
do get some serious compression.

A little searching on the web lead to this: 'Now for the kicker - size
and number of files: MrSID - 80.4 MBs and 2 files; JPG - 21.5 MBs and
3 files; JPG2000 - 4.5 MBs and 3 files; GeoTIFF 24-bits - 121.8 MBs
and 1 file; GeoTIFF 8-bit - 10.4 MBs and 1 file. Clearly, the JPG2000
packs the greatest image bang for your MBs.'

>From 
>http://www.evs-islands.com/2008/08/comparison-mrsid-jpg-jpg2000-geotiff-24.html

A word of warning with H2 - I made a similar recommendation to your
architecture and had someone get burned with data corruption.  This
was a couple years ago, so it may be better now, but it's tough if
anything goes wrong with H2 because there's not lots of tools to get
in and diagnose and do backups and the like.

Note also that GWC can support WMS directly, by under/over sampling
tiles to combine in to the image requested.  It can't reproject, but
should allow client access.

One big question with MBTiles in GeoServer is if it should be a
coverage format, or just read direct by GeoWebCache.  Recently I
convinced myself of the latter.  You could do either, but I think
doing it in a coverage format breaks some expectations.  It works
great if the MBTiles are just pure raster data.  But if it had vector
data go in to it at all then sticking that through a WMS is likely
going to make things look crappy, as you'll be sampling and projecting
rasterized vectors.  The other thing is the UTFGrid interaction stuff,
which would be entirely lost if you do a coverage reader, but could be
incorporated in GWC.  So that if someone made an MBTiles file with
utfgrids they could work.  And just in general doing it in GWC I feel
sets the expectation more properly, that it's tiles.

I believe MBTiles should be thought of as more an interactive display
format.  It's like the modern version of a printed map - something a
designer composes to be exactly as they want.  Treating it as a raster
datastore I think only works unless you're just doing pure raster data
in it.  But it's not a great format for pure raster data, because it
only has one projection, one tile size, etc.  I think there is a need
for a tile format for mobile devices, but MBTiles would need to evolve
a bit to meet that.  But then it risks sacrificing its simplicity.

Re: [Geoserver-users] WFS 2.0.0 stable release ?

[Chris Holmes]

The implementation is quite complete.  It'll be in the next (first) 2.2.x
release.  That will probably be a beta release, and will take a bit of time
to get stable.  Afaik no one has definite plans / timeline to do that
release, but it could be soon, as there's lots of nice stuff (complex
features, time, workspace improvements, security improvements) that would
be good to start to get out to people to test.

If you happen to have funding you could likely contract someone to push a
beta release out, or even to push it to 2.2.0.

Re: [Geoserver-users] Open Google Doc Spreadsheet on Geoserver

[Chris Holmes]

Currently no.

Google Fusion tables probably make more sense than straight google doc
spreadsheet, as they have spatial types and I don't believe spreadsheets
do.  But I guess you could do like x,y in a spreadsheet.  Or if we had cool
joining capabilities it'd be possible.

But we don't even have Google Fusion table support yet.  So probably pretty
far away from being able to meet your needs, but an interesting thought.

Re: [Geoserver-users] wps and service area

Note there's some open source code that can handle this, and there are some

The core project is http://opentripplanner.org which has built a really
vibrant open source community with a number of deployments in multi-modal
trip planning.

But the cooler thing is http://analyst.opentripplanner.org/ - taking that
core functionality and turning it to processes for analysis.

I'm not sure what kind of skills / resources you have Fabio, but if you
want to help on getting those process in to GeoServer that'd be really
great.

Re: [Geoserver-users] Status INSPIRE WFS in GeoServer

[Chris Holmes]

Oh, and a note for everyone reading this thread, that I learned recently:

AppSchema works much, much better on trunk (2.2) of GeoServer than 2.1
or 2.0.  It got a lot of performance and scalability improvements, and
is running in production for GeoSciML.  You can get nightlies from
http://gridlock.opengeo.org/geoserver/trunk/

Also talked with CSIRO and we agreed it'd be a good idea to put out a
beta or alpha release off of trunk soon.  Need to figure out if we can
find the time to merge in WFS 2.0 stuff soon, along with any other
stuff people may have ready for trunk, but either way it'd be good to
have an easier to use release of all the AppSchema improvements.

I know Gabriel has a way of looking at the headers in the response,
but I forget exactly what that is.

What I do is look at the GWC page in GeoServer in the disk quota
section.  If you move around the map some and then reload that page
the amount of data cached should increase.  You can check to be sure
there are differences by checking maps on the GWC end point, as it
always caches.

Re: [Geoserver-users] getting back an array of raster data in txt

Using the WCS should allow you to do that (and a lot more).  Can read up on
it at http://www.opengeospatial.org/standards/wcs  GeoServer supports 1.0
and 1.1

If you want it to get on to worldwind there's a plugin you can use that will

There's a chance that the native srs may work too, I can't remember.  But I
think it may have been difficult to auto-configure the grids.

We made improvements so it would cache all Styles, not just the default.
 This was funded for GeoNode, which makes use of it.  I believe it will make
a new tile set for each style that you have, which will be automatically
truncated if you change them.

Re: [Geoserver-users] How to get metadata such as the native bounding box for raster data through REST?

[Chris Holmes]

You want coverages instead of coveragetypes.  The base inspiration for the
names is the WFS vs WCS specs, WFS calls layer categories featureTypes, WCS
calls them coverages.

So
http://www.aifdr.org:8080/geoserver/rest/workspaces/hazard/coveragestores/Lembang_Earthquake_Scenario/coverages/Lembang_Earthquake_Scenario.xml


works for me.

I think the GS rest is a bit confusing, as it'll generate some stuff that
can throw you off a bit - I got a bit turned around navigating when putting
in the wrong stuff.  But what you can generally do is go a level or two up
and see the links it has under it.  So if you go to:

http://www.aifdr.org:8080/geoserver/rest/workspaces/hazard/coveragestores/Lembang_Earthquake_Scenario/

Then it'll point you at its list of coverages:

http://www.aifdr.org:8080/geoserver/rest/workspaces/hazard/coveragestores/Lembang_Earthquake_Scenario/coverages.xml

 Which then finally has the proper link with 'coverages'.

It'd probably be better if we didn't generate anything at all if you put in
the wrong word for 'coverages'.  It looks like basically it matches anything
and tries to generate the same stuff it would if you put it in correctly.
 Not sure if that was by design, or just neglected to turn off one of the
paths.

This I'm not sure how to do.  I imagine you could use GDAL command line in
some way http://www.gdal.org/  Or a desktop GIS.  Basically I believe it's a
pre-processing step before you get it in to GeoServer.

This should happen with just getting it configured right (adding your
geotiff as a 'store' and then publishing the layer.  Basically it's
http://docs.geoserver.org/stable/en/user/gettingstarted/shapefile-quickstart/index.htmlbut
pick geotiff instead of shapefile).   As long as the lamberts
projection
is right then GeoServer automatically handles reprojection.  You just need
to request srs=EPSG:900913 for the projection.  Can play with requests
using http://docs.geoserver.org/2.1.x/en/user/tutorials/wmsreflector.html

I would recommend you use GeoWebCache, as it'll cache your tiles for faster
access.  It's embedded in GeoServer
http://docs.geoserver.org/stable/en/user/geowebcache/index.html  If you're
using GMaps API directly then GWC has a nice shortcut you can use, see
http://geowebcache.org/docs/current/services/gmaps.html

I believe the best practice way to do this is to make an SLD for each with
the scale denominators you want it to display at.  See like
http://suite.opengeo.org/recipes/#sld/polygon/zoombasedpolygon  Though you
just probably need the scale for each layer, not a bunch of rules.

Then after you have each layer at the scales you want put them together in
to a 'layer group'

Re: [Geoserver-users] Anyone using GeoServer for INSPIRE services

[Chris Holmes]

I think Emmanuel Seguin at IGN France may have already coded #1.  I just
made a jira for it - http://jira.codehaus.org/browse/GEOS-4595  Hopefully
he'll add his patch there.

He may also have some insight on the others.

Re: [Geoserver-users] Restrict WMS Output formats

[Chris Holmes]

Weirdly I don't think there is a way to do that.  Seems like a common enough
request, but I can't personally remember anyone else asking for it.  I can't
even think of a clean hack to accomplish it, though maybe some else can (or
knows a way to disable it properly).

Re: [Geoserver-users] Geoserver memory & connections management

[Chris Holmes]

Hey Hari, vote.mapview.in looks cool.  Have you considered using GeoWebCache
for it?  Looks like you're doing large, single tile requests.  If you stick
GWC in front of it then you could put a lot less of a load on the server,
since most places that people look at would get cached.

Re: [Geoserver-users] keeping the GWC cache fresh

[Chris Holmes]

If you're using the embedded GWC in GeoServer then it should get
automatically refreshed if you use a WFS-T transaction or change a style.
 We use this by default with local layers in our GeoExplorer app -
http://suite.opengeo.org/geoexplorer.  All layers are automatically cached,
but refresh if you edit or change a style.  If your changes are happening
outside GeoServer you can set up GeoWebCache to read a GeoRSS feed and
refresh based on that - it should report to GWC what changed.

Re: [Geoserver-users] WMTS

[Chris Holmes]

GeoServer by default includes GeoWebCache, and exposes all layers as WMTS
(among other tile formats).  See for example
http://suite.opengeo.org/geoserver/gwc/service/wmts?REQUEST=getcapabilities
Just go to /gwc/service/wmts from your geoserver base directory.

Actually there's been a lot of progress since the time of that blog post.
There was a 'sprint' to add real mobile support, there's a good overview at

I don't think it's not in a full openlayers release yet, but should be soon,
and you should be able to try it out, just ask on the OL list.

Re: [Geoserver-users] Tiling & labelling

[Chris Holmes]

That's really nice, and I imagine it'd work well.  Indeed you more want to
see _something_ fast, I feel like it's ok if the labels load a bit more
slowly.

I wonder if there's some way we could make that set up easier for users.
Like make a special layer type in OpenLayers, and some way to ease
configuration on the geoserver.  Like if we had like WMS options for 'no
labels' and 'only labels'.  And then just did that at the renderer level,
instead of making people create separate SLD's.

And on the openlayers side we could make a layer type that can take two
URLs, the cache and the dynamic label WMS.

Note that you can use really large meta tiling.  I think ESRI's default is
4096x4096, so 16x16 256 pixel tiles.  Though at that size it's much better
to pre-seed.

This is kind of a 'holy war' topic, with both views very well covered in

Fogel ends up falling slightly on the side of the behavior we have here for
open source projects.  I think a change would probably screw up a lot of
people who are always on the list, so it's probably going to be a tough
battle to convince enough of the Project Steering Committee (who has

Re: [Geoserver-users] App Schema and GeoJSON

[Chris Holmes]

No complex feature to GeoJSON transformation is possible now.  I think the
GeoJSON spec doesn't give any recommendations on complex features, though I
suppose it should be fairly straightforward.

Going XML to JSON wouldn't be nearly as fast as going straight to JSON from
the actual Feature objects.  I don't think it should be hard to extend the
JSON writer to iterate through full complex features, and I believe would be
a welcome patch.  If you're interested someone more knowledgeable than I can
direct you at the code and what you'd need to do.  Should be fairly self
contained, relatively easy to wrap your head around and get coding.

It actually doesn't, yet, that I could find.  But it's pretty straight
forward, most parameters (all CssParameters for sure) can take an
ogc:expression.  Which gives you the flexibility to put in property names,
filter functions, etc.  For a more advanced example see
http://docs.geoserver.org/stable/en/user/styling/sld-extensions/substitution.html
This is client supplying the values, but you can see that the
WellKnownNameand the Fill have more complex expressions in them.
Those also could be
ogc:PropertyNames, afaik.

Re: [Geoserver-users] Any interest in a Google Fusion Table Datastore?

[Chris Holmes]

That's a great idea - it could be super useful for people who have non
spatial data and can use fusion tables to geocode it.  It didn't occur to me
you could connect straight to it.  We had been contemplating leveraging that
geocoding capability for GeoNode, but I think it could be a nicer story to
be able to tell people to upload there and we could connect directly.  So
yeah, I think the big win is the built in geocoding, less so the storage
thing, as spreadsheet people can understand it, no need to convert to a
shapefile or figure out geocoding.

Are there limits to how much data can be put in?  If not I wonder if it has
any type of spatial index.

Just to clarify a few things, to make sure we're on the same page.
Publishing full metadata is a task for a CSW, like GeoNetwork, as Andrea
says.  One current hassle though is that GeoServer has a subset of full
metadata fields (title, abstract, keywords, etc.), so currently one
publishing a service has to manually keep the two in sync (the geonetwork
full metadata and the geoserver service metadata).  We solve this problem in
GeoNode - http://geonode.org  It lets you edit metadata in one place and
then keeps both geonetwork and geoserver in sync.

The GeoServer metadata link is just to provide a link to an ISO or FGDC
metadata document, and it's up to the user to keep it all up to date.  In
GeoNode we automatically make the metadata link in GeoServer, and the
WMS/WFS links in GeoNetwork.

I'm actually talking to our client right now about potentially improving it,
doing something where GeoServer is able to read in or transform the linked
metadata in to the capabilities document, to help avoid filling it all out
multiple times.

Re: [Geoserver-users] Inspire plugin

[Chris Holmes]

The plugin is to add INSPIRE specific view service parameters.  We're still
working on it, and I keep neglecting to do a blog post on it.  Right now it
populates the inspire extended capabilities params with geoserver metadata
fields.  The only new editable one is the language though.  We're figuring
out now how to handle more.  You can get versions that correspond with
releases at

http://files.opengeo.org/inspire/

But there are 3-4 bugs fixed that need to wait for RC2.

Digging in to it, looks to be that beta1 works, so was probably introduced
during the WMS refactoring.  I'm pretty surprised no one has seen this
before though.  It consistently fails with tiger_roads and probably any of
the rasters.

[Chris Holmes]

You're going to need to provide some more info to give anyone the chance to
help solve the problem.

Can you get what the actual transaction request that MapInfo is sending?

Posting the logs with the logging level turned up also may help.

It's not new.  But it's just a field you fill out, doesn't do any automatic
linking with anything.

I'm not sure what you mean here.  But if you fill out that metadata link on
the layer then it'll include that in the capabilities in GeoServer

Yeah, it's not a great link, they never made really readable links, so it's
just the CSW call.  But an example is:
http://demo.geonode.org/geonetwork/srv/en/csw?outputschema=http://www.isotc211.org/2005/gmd&service=CSW&request=GetRecordById&version=2.0.2&elementsetname=full&id=7bbcae0b-37ba-46f1-8293-3bb5598d7964

We've talked about doing some nice direct GeoNetwork/GeoServer thing where
they communicate directly together, but no one's implemented.  In our
GeoNode project we do keep the two in sync, but we abstract out the UI for
both, so using Django is the only way to edit the service properties for
either.  It's nice because it keeps the links between the two right, and
also has their abstract, keywords, etc. stay the same.  But we use python to
do the coordination, using the service interfaces of both (CSW transactions
and RESTConfig), so we can't easily incorporate it in to GeoServer.

We decided to do that in GeoNode.  I suppose one could build a java metadata

Nope, for now you have to keep them in sync yourself.

Re: [Geoserver-users] ImageMosaic for timeseries dataset?

[Chris Holmes]

Hey Simone, did you guys ever get time stuff working with vector stuff as
well?

It'd be awesome to get 'time' in as a feature for geoserver 2.1.x, and it
sounds like you all did most of the work already, it just needs to be
documented?  I could probably help out with a bit of time to help document,
and/or in a few weeks OpenGeo may be able to put some resources towards it.
If it's there we also could soon work on a GeoExt time slider or something,
maybe incorporate simile, that could show off the capabilities.

Re: [Geoserver-users] App Schema Transactions

Nope, it hasn't.  I can get you in touch with the guys who wrote it, maybe
if you have a bit of funding they can clean it up and contribute it.  Though
I know they intend to, they just haven't found the time.  People expressing
interest like this will probably help them, especially if you're willing to
help improve it and bug fix it.

Re: [Geoserver-users] Creating Repository

[Chris Holmes]

You also could try http://geonode.org  It built on GeoServer and has a
shapefile/geotiff through the web uploader, and we're working on an ftp
uploader (which will be a geoserver community module).  It uses Django as a
web framework, and its user access hooks in to GeoServer's security, so you
can use its gui to limit user access.  Also does things like styling through
the web and provides CS-W on layers uploaded, with metadata editing that
gets picked up by GeoServer and GeoNetwork.  It's a lot of software to set
up and coordinate, but we just about done with ubuntu packages that should
be released shortly.

Re: [Geoserver-users] Pagination and WFS

[Chris Holmes]

There are definitely plans to, and I don't think it should take too much
work, we're all just waiting for an opportunity or someone to fund it.  I
believe it will be necessary for WFS 2.0, so it's on the roadmap for sure.

Re: [Geoserver-users] mySQL

[Chris Holmes]

MySQL has limited spatial capabilities - they do have geometry storage and a
spatial index.  The main problem is that all spatial operations are done
against the bounds of the geometries.  So they're not exactly accurate.  So
if your polygons are all boxes then it'll work great, if not then it'll also
return points that are outside of polygon but in its box (at least this is
my understanding of MySQL functions).  Now, GeoTools does have the
capabilities to deal with this - to not pass the spatial filters to MySQL to
try to handle, but to do the filtering itself.  This is what we do for
Shapefiles.  I'm not sure where exactly the MySQL datastore stands though,
if it does the right thing.  It was coded pretty quickly and hasn't seen a
lot of love.  You should be able to test it pretty easily though.  And if it
didn't work but you could get dirty with java code it may not be that hard
to fix.

GeoServer does not have the ability to join across datastores, so your
second idea won't really work.

hope that helps,

Chris

Re: [Geoserver-users] App Schema Transactions

[Chris Holmes]

Note there are some developers who have built support for parsing complex
GML features.  They just haven't got the go ahead and time to contribute the
code back.  Though I'm meeting them today, so will mention that there is
real community interest.

Re: [Geoserver-users] App Schema Transactions

[Chris Holmes]

I'm not an app schema expert, but I'm pretty sure it's a lot more involved
than just reusing current mappings.

I know of one group that's done transactions against app schema stuff, but
I'm pretty sure they just did transactions against the underlying flat
schemas.  It'd be relatively easy to set up some triggers to make sure that
things get updated properly.  But doing it completely generically sounds
like a big task to me.  Though someone with more app-schema knowledge
hopefully will sound in with more specifics about the possibilities.

best regards,

Chris

Re: [Geoserver-users] More CPU or more RAM?

[Chris Holmes]

How much data is going to be served up?  The advantage of more memory would
be that your shapefile disk block would make it in to the OS disk cache, and
then things would go quite fast.  Of course once that happens then you'll
definitely be CPU bound, so if most of your data will fit in the 7g of ram
then the more cpus will be faster.  Arne knows this stuff much better than
I, and he's the one I learned from, but giving less explicit memory to java
and postgis may help (or maybe it's smarter than that).

I guess the other thing to consider is how many concurrent users.  Even with
tiling I think you don't get more than 4 threads per user, so if you only
have a few concurrent users than all the extra cpus won't help much, since
geoserver's renderer doesn't use multiple cpus per thread.

Re: [Geoserver-users] Geoserver: reference system

[Chris Holmes]

One thing you can use to help you get the right request is the WMS
Reflector.  See
http://docs.geoserver.org/stable/en/user/tutorials/wmsreflector.html

You can make a request like
http://suite.opengeo.org/geoserver/wms/reflect?layers=world and get a
default image of the full bounds with the default project projection.

Then you can change the projection,
http://suite.opengeo.org/geoserver/wms/reflect?layers=world&srs=epsg:900913

Or fun ones like
http://suite.opengeo.org/geoserver/wms/reflect?layers=world&srs=epsg:3032(obviously
polar projections aren't really supposed to be done on world
maps).

Can throw on formats as well, even get openlayers output -
http://suite.opengeo.org/geoserver/wms/reflect?layers=world&srs=epsg:3032&format=openlayers

[Geoserver-users] download stats

[Chris Holmes]

Sourceforge seems to have a cool new download stat feature.

http://sourceforge.net/projects/geoserver/files//stats/map?dates=2010-02-01%20to%202010-11-17

Looks like 1/4 of all GeoServer downloads are from China.  And there's not
even yet a chinese translation for 2.0.x.  We should probably try to do more
outreach and see if we can get some contributors to the core, as there must

We are only 215 downloads away from 200,000 all time downloads.

You can remove the extensions though, as that always inflates our download
numbers, see

137,000 is actually higher than I thought it would be.

Re: [Geoserver-users] Mastermap

[Chris Holmes]

I've never done it, so I don't really know.  I know it's super easy with
Safe FME or Snowflake software's tool.  You also could probably do it with
OGR, just try to transform from the gml to postgis.  Or Oracle, or whatever
your spatial db is.

Re: [Geoserver-users] Mastermap

[Chris Holmes]

Note though that many people have successfully got GeoServer working with OS
mastermap data.

This includes OS OnDemand -
http://www.ordnancesurvey.co.uk/oswebsite/services/osondemand/index.html
Which is OS's primary WMS service for their customers.  And I know of many
others who have got it working.  But you do have to do some transforms from
the OS mastermap GML to load it in to GeoServer.

Re: [Geoserver-users] WMTS in geoserver

[Chris Holmes]

Actually OpenLayers got WMTS support in July, see
http://openlayers.org/blog/2010/07/02/wmts-support-in-openlayers/

Demo at http://openlayers.org/dev/examples/wmts.html (against GeoWebCache
embedded in GeoServer).

Re: [Geoserver-users] Google Maps and GeoServer without open layer

[Chris Holmes]

You also might check out using GeoWebCache, since if you use straight WMS
with GWC you can swamp your server with requests pretty fast.

See http://geowebcache.sourceforge.net/docs/current/services/gmaps.html

All GeoServers ship with GWC, at geoserver/gwc, like
http://suite.opengeo.org/geoserver/gwc

So you should be able to do something like:

var tilelayer = new GTileLayer(null, null, null, {
  tileUrlTemplate:
'http://localhost:8080/geoserver/gwc/service/gmaps?layers=layer-name&zoom={Z}&x={X}&y={Y}&format=image/png',
  isPng:true,
  opacity:0.5 } );

(There's a slight chance that needs to be updated for v3, but I think it
should work ok)

Re: [Geoserver-users] Is it possible to edit SHP files via Geoserver Web interface?

[Chris Holmes]

The way to edit a shapefile through the web is using the WFS-Transactional
standard.  This is a web interface to perform changes on the underlying data
format, be it shapefile, postgis, oracle, etc.

GeoServer does not ship with a wfs-t client.  But there are a number of
them, like uDig, and I think qgis may now support wfs-t.  These are both
desktop.  On the web there's openlayers, and we've built some geoext
components on top (which we hope to eventually get in to the geoext
library).  See

http://suite.opengeo.org/geoeditor/

Re: [Geoserver-users] Is it possible to use dynamically generated SLD?

[Chris Holmes]

Part of the WMS spec is you can just use the SLD parameter.  Instead of
saying style=StyleName you say SLD=http://link.to/style/name.  See
http://old.nabble.com/Applying-a-remote-SLD-to-a-Openlayer-GetMap-request-td15767436.htmlfor
some discussion of it.  It's specified in 1.0 of the SLD spec, see
http://www.opengeospatial.org/standards/sld

If you're wanting to do more there are a couple things that give you even
more power:

http://docs.geoserver.org/2.0.x/en/user/styling/sld-extensions/substitution.html
and

Re: [Geoserver-users] WMS Max Image Size Problem

[Chris Holmes]

Looks like out of memory.  Did you try increasing the memory to your servlet
container to see if it works?

See
http://docs.geoserver.org/2.0.x/en/user/production/container.html#optimize-your-jvmfor
the java flag to increase it.  You can pass that in to the start up of
any container.

I don't see anything attached?  Could you perhaps put the images online and
supply links to them?

Re: [Geoserver-users] Geoserver print module source

[Chris Holmes]

I believe it's at http://www.mapfish.org/svn/mapfish/print/trunk/  Part 
of the mapfish project, would be great to contribute your fix back there.

Yes.  The best thing to do is take screen shots from several zoom levels 
if you have scale dependent SLD rules.  If all the colors are the same 
at all zoom levels then you can just use one zoom level.

Nope.  What the palette is doing is picking which are the most important 
256 colors out of the thousands that a png24 renders.  Then it just sets 
those as the ones for GeoServer to use when rendering, which makes 
things much faster.  And generates the smaller images.  So all the 
palette contains is a list of those 256 colors - no geo referencing needed.

I have no idea...

Re: [Geoserver-users] Labeling a "static text" ie. not xyz

I'm not sure if you're looking something more complex, but if just want to
hard code in your SLD the Swamp Forest I'm pretty sure you can say


Swamp Forest

Re: [Geoserver-users] how to make map pretty

[Chris Holmes]

It's on the GeoServer side, not OpenLayers.  It's hard to give advice on how
to exactly make it pretty, as it depends on many factors.  But there's a
good page on all the options you have for labeling, at
http://docs.geoserver.org/2.0.x/en/user/styling/sld-reference/labeling.html

Re: [Geoserver-users] Geo-ext Styler

[Chris Holmes]

It's evolved to be part of the OpenGeo Suite.

You can see a demo at
http://suite.opengeo.org/geoserver/www/styler/index.html

You can get the source at http://svn.opengeo.org/suite/trunk/styler/

The community version of the suite can be downloaded at
http://opengeo.org/community/suite/download/

I'll update that wiki page.
