[mapserver-users] AGG Rendering

2009-04-03 Thread Andrew Ayre
Hi! I can't seem to get AGG to work. Currently my output is not 
antialiased. Can anyone give me some hints? Thanks!


Note that I have built AGG 2.5 with freetype support. Also note that I 
needed two

That says it all: Your mapserv binary doesn't support PNG. Says so in 
your mapserv -v line too: note the lack of SUPPORTS=AGG


I'd suggest re-running your ./configure and check for the lines where it 
mentions that it's checking for AGG, cuz something's not right there.

Re: [mapserver-users] Using the SQL Server 2008 Plugin with a Geography column

2009-04-03 Thread Tamas Szekeres
Hi,

The MSSQL 2008 driver only compatible with the Geometry data type at the
moment. In case if the Geography data type is used the spatial filter should
also be specifyed as Geography which is not the case in the current
implementation. You might want to submit a ticket describing the issue and
we could probably get it implemented in a future release.

Best regards,

Tamas




2009/4/2 joncoign jnco...@knology.net


 To clarify I have a column in SQL 2008 of type geography that I would like
 to use in map server. I have been able to do this using the OGR ODBC driver.
 However, when trying to use the Native SQL 2008 driver that has been added
 to MS4W 2.3.1 I get the error message sys.geometry is incompatible with
 sys.geography when executing the query captured by profiling the database
 request.

 It appears as though the SQL 2008 driver either assumes that it will always
 (and only) be used against geometry columns or there is a configuration
 setting I that I can use to tell it that the internal datatype is geography
 and as such  builds the WHERE clause using the geomertry type for the
 bounding box filter.

 SQL Excerpt:

 the_geom.STIntersects(Geometry::STGeomFromText('POLYGON(...)') = 1

 where in this case the_geom is a Geography column that cannot be used in an
 STIntersects call with a Geometry object.

  I am hoping someone can tell me about the configuration option to change
 this behavior or confirm that it does not exist so we can discuss the
 possibility of adding such an option.

 Let me know if you need additional details.


 There are two ways to define an object spatially in 2008 one as type
 geometry and one as geography.

Re: [mapserver-users] Dynamic 'OnMouseOver' Info generation vomPostGIS/Postgres

2009-04-03 Thread Steve Lime
To do this you need some sort of an observer for the map and an image
map is
one way to do that. Here's an example:

  http://www.dnr.state.mn.us/ice_out/index.html

In this case the data to be displayed are encoded in the image map
produced
by MapServer (I used the template mechanism). So, onMouseOver, a
function
is called to display the data object. You could just as easily wrap an
ajax call
in that function. You'd need to store a unique ID as part of your image
map
sufficient so that you can query postgres. Then the function is called
you
pass the ID and then use that to retrieve the additional data.

The image map will work when you have a relatively small number of
reasonably
spaced features AND you're interface is not particularly interactive. I
don't 
think it's possible to combine an image map with your typical pan/zoom
operation.

Another solution is create a polling capability in your application and
tie it to
some sort of an event, such has pausing the mouse for a few seconds. If
that
event happens you do a spatial query to see if the user is hovering over
anything
and if so you do something. Here's an example site:

  http://www.dnr.state.mn.us/waters/csg/index.html

If you hold your mouse over one of the points on the map you'll get
details about
that feature. At each pause a query is done behind the scenes and if
something
is found a popup is populated. It's kinda chatty but works. Watch the
above page
in FireBug so see the network communication. OpenLayers has a great
hover control 
to do this sort of thing. You can also use click events, like so:

  http://www.dnr.state.mn.us/waters/csg/index_copy.html

Creating the content to send back will depend on the data. In the above
cases I use
MapServer templates to build it. You could use your favorite scripting
language to do
so as well.

Hope this helps!

Steve

 Heiko Schröter schro...@iup.physik.uni-bremen.de 04/02/09 7:44 AM

Hello all,

we are displaying satellite measurement geolocations with Mapserver and 
PostGIS/Postgres underneath.

I would like to add a feature (similar to the MapServer:ImagMap stuff)
that 
displays some more info about the point on which the mouse is over
inside the 
map. i.e. geolocation, name of datafile, value or so. These infos can be

sourced from the Postgres db. It is ok to just show these infos on the
bottom 
window frame (like the MapServer:ImageMap example).

How do i create the html code (javascript or php or whatever needed)
with the 
dynamic content piped back from the Postgres db ?
Sorry if this is an obvious question. I did read the ImageMap and
Template 
stuff, but i cannot get grip to the logic when the data are coming from
a db.

Any pointer to more info or background knowledge deeply apreciated.

Thanks.
Heiko

Re: [mapserver-users] How to access Templating: Map Geometry Variables(or Equivalent) from OGR Connection

2009-04-03 Thread Steve Lime
This would be a feature request. The runtime subs are done well ahead of the 
computation
of things like map extent. This would be a relatively simple hack and I can 
show you where
in the CGI code to try it out if you'd like.

Steve

 joncoign jnco...@knology.net 04/02/09 10:47 AM 

I didn't get a response to my previous post so I wanted to rewrite it and 
attempt to make it more general. We make OGR ODBC requests to SQL Server 2005 
with MSSQLSpatial extensions. To get good performance out of this system and to 
further secure the paramters we have been using stored procedures so we can 
optimize the queries inside of the database. This results in a connection 
object that similar to the following:

CONNECTIONTYPE OGR
CONNECTION OGRVRTDataSource
OGRVRTLayer name='GDT'
 
SrcDataSourceODBC:MSSQLSPATIALDSN,states/SrcDataSource
SrcSQL
EXEC dbo.MappingGetStates %BBOX%
/SrcSQL
GeometryField encoding='WKB' field='the_geom' /
/OGRVRTLayer
/OGRVRTDataSource
 DATA GDT

We have had good luck using Variable Subsitution from the querystring however, 
sometimes it would be useful to be able to access additional varaibles from 
within mapserver such as those defined in the Templating section of the 
documentation (an alternative method to access equivalent data would be full 
acceptable). Specifically, it would be nice to have access to [mapext], [minx], 
[miny], [maxx], [maxy], [rawext], [mapext_latlon], [minlon], [minlat], [maxlon] 
[maxlat]. To be explicit I am asking is there a way to use these inside of the 
SrcSQL section of the CONNECTION.

Is this functionality currently available and something I have overlooked in 
the manual or would this fall under the category of a feature request?

Looking forward to SQL Server 2008 I think this approach will still have merit 
as it offers quite a bit of additional flexibility in writing and optimizing 
the query over what I have been able to achieve thus far with the Native SQL 
Server 2008 driver. I should stipulate I have only been using the new driver 
for a couple of weeks so I may not find it as limiting after additional testing.



I have a WFS Server layer defined and have recently needed to provide this 
service in an alternate projection. The Data is in EPSG:4326 and I need the WFS 
Service to provide it in Spherical Mercator (SM / EPSG:900913). I have this 
working properly with the layers projection definition and wfs_srs.

The problem I have is that previously I was passing the %BBOX% parameter to the 
database stored procedure using an OGRVRTDataSource  referencing an ODBC 
connection. 

When reprojecting the WFS layer the %BBOX% does not get reprojected so it gets 
sent to the database in meters as defined in SM. I could reproject this in the 
Stored Procedure, but my client would prefer I treat their DB as a black box 
and not make changes. Am I correct in assuming that %BBOX% comes unaltered from 
the querystring? Is there another variable I can use with Variable substitution 
to get the BBOX in the data's projection? Or is there a way to reproject %BBOX% 
variable? 

It is critical that I can filter the data coming out of the spatial DB before 
it gets to MapServer for performance reasons.

Any help is greatly appreciated.
Jon

 Moen, Paul T. pm...@nd.gov 04/01/09 3:55 PM 
I changed my Geos to version 3.0.3 and the error changed from Segmentation 
fault to Bus error.
I also looked at the ticket Assefa indicated below and am wondering if that was 
related to the buffer or to the same problem I am having?  The script I am 
having problems does nothing more than create a new shape object from a wkt and 
then re-output the wkt from the shape object.  The object seems to be created 
fine, because I can get the number of lines with $drawnShp-numlines.  I can 
also create a new shape object with the other shape object constructer as 
follows and the output works.

Xphp
dl('php_mapscript.so');
$drawnShp = ms_newShapeObj(MS_SHAPE_POLYGON);
$line = ms_newLineObj();
$line-addXY(1207657,478875);
$line-addXY(1208230,478275);
$line-addXY(1207452,477811);
$line-addXY(1207043,478520);
$line-addXY(1207657,478875);
$drawnShp-add($line);
error_log($drawnShp-numlines);
error_log($drawnShp-towkt());
?

Is this specifically a problem with Geos 3.1 and the function 
ms_shapeObjFromWkt()?  Which version of Mapserver will have the patch in ticket 
2929?

Thanks,

Paul

Hi !

I got a WFS server with two layers inside  -nothing special. But now something 
weird happens:
When I try to build them in in a wms/wfs client together they are not shown. If 
there is only one layer embed in the client it works without any problems.

Anybody knows why ?


And another strange thing is the size of files (xyz.tmp.gml and xyz.tmp.gfs) 
which are created in the tmp-folder. The size of them is about 4 - 11MB, and 
that's why every request lasts a few second (too long I think.. because the 
data isn't that large). Or is this case normal?


(Mapserver: 4.10)

thank you
kind regards
