Re: [mapserver-users] Spatial Filter with WFS

[Rahkonen Jukka]

Hi,
 
This one may not be the only problem, but I would start by creating a valid WFS 
1.1.0 request by giving a filter as gml3 or alternatively go on with using gml2 
filter but changing version to WFS 1.0.0.  Here below is a WFS 1.1.0 request 
that works against deegree.  It does not necessarily work against Mapserver 
because it can well be that Mapserver does not support gml:Surface, even if the 
surface is a plain polygon as in this  case.  However, you see that gml3 does 
not use

Aihe: [mapserver-users] Spatial Filter with WFS
 

Dear MapServer-User,
 
I configured MapServer version 5.6.5 as WMS- and WFS-Server to offer 
information about land and properties. I use PostgreSQL/PostGIS (8.4.4/1.5.1) 
as datastore in this case. The spatial reference system is EPSG:25832 und the 
type of the geometry is MULTIPOLYGON. OS is Suse Linux Enterprise Server 11, 
Servicepack1.
 

WMS and WFS work fine until I use a spatial filter within the 
getFeature-Request of the WFS. In this case the response doesn't deliver any 
features. Nevertheless the number of features (e.g. numberOf Features='4') is 
correct. I tried this out with a couple of different boundingboxes and the 
known number of features that intersect these boundigboxes. In all cases I do 
not get any features back, but always the right number. So it seems that at 
least the intersection of the boundingbox and my data works correctly.
 
Please take a look at the following request and response that illustrate that 
problem:

Hi all,

As noted MapServer does not support gml:Surface. The original request 
with gml:Polygon seems to be correct.
Andreas, is it possible to package it and send it to me off list. I can 
quickly check what the issue is.

[mapserver-users] SLD and OUTPUTFORMAT compatibility?

[Martin Ouellet]

Hi all,

I have 2 two differents settings for symbolize my lines (refer to SLD
settings below):

1) a dashed line which is working *only when I specify the
outputformat:  *DRIVER
"*GD*/PNG"
**Note that with the driver GD/PNG, the external graphic below is not
working but the symbol (ico-ulaval-flag.gif) is copied locally in the
/ms_tmp directory.
It seem to be ignored by mapserver (but raising no error)...

2) a external graphic which is working *only when I specify the
outputformat:  *DRIVER "*AGG*/PNG"

Q: Is there a way/config to support both at the same time?

any advice?

Thanks you in advance!

is how Geoserver 2.1 beta 1 writes out on multipolygon as gml3


Yes with wfs 1.1, It should be gml3. Note that the parsing of the gml 
tree is done through OGR and I believe OGR is flexible to read the 
different syntax for a  tag. We do not schema validate the 
gml in MapServer and take as assumption that It is good, if it is parsed 
properly by OGR.

[mapserver-users] Classifying Dynamic Points

[Burgholzer, Robert (DEQ)]

I have succeeded in generating a point layer dynamically thanks to a
wiki entry
(http://trac.osgeo.org/mapserver/wiki/PHPMapScriptAddPointScale), but I
find that I do not have the understanding that I need to color code
these points by their value.  These values are precipitation summaries,
that I want to apply a color ramp to.

 

I can't figure out how to add an attribute other than the x,y,z, and m
coordinates.  Is this possible?  I really want to do this without having
to use my postgis connection, but rather, with this dynamically
generated layer approach if possible.

 

Thanks,

r.b.

Re: [mapserver-users] SLD and OUTPUTFORMAT compatibility?

[Yewondwossen Assefa]

Hi Martin,

 Can you try to check the map file after the sld has been applied: you 
can do that by setting your map file in debug and checking the log file  
look for something like "...Map file after SLD was applied"  (ex: 
something like this):

CONFIG  "MS_ERRORFILE" "f:/msapps/gmap-ms40/htdocs/gmap.log"
DEBUG 5

We can then check why the same style setting is not drawing the same way 
with the 2 drivers.  Please also indicate which version of MapServer you 
are using.


regards,

Hmm, maybe a *little* more work than I was hoping for, but that might be
a workable solution.  Thanks for the tip/link.  

 

Guess the question still remains, do these pointObj's have no other
parameter attributes?

Hi Assafa, thanks for your quick reply

I'am working with mapserver 5.6.5 (installed form elgis RPM -
http://wiki.osgeo.org/wiki/Enterprise_Linux_GIS)

Here the requested files:

I've prefix the files with "aggpng_working" of identify the working example
1) aggpng_working_mapserv.log (log of mapserver for this case only)
2) the working scenario generate 2 mapfile:
aggpng_working_4cebdca9_13c_2._sld.map
aggpng_working_4cebdca9_13f_2._sld.map

I've prefix the files with "gdpng_notworking" to identify the case who's not
working
3) gdpng_notworking_mapserv.log (log of mapserver for this case only)
4) gdpng_notworking_4cebdbff_7fc0_2._sld.map

Thanks again...

Re: [mapserver-users] WFS element datatypes are all strings - how to set as integer?

[Frank Warmerdam]

Hi,

I'm looking to use mapserver to provide WFS data layers to QGIS clients. 
I need to display the layer using a data field to control symbology 
(symbol size), but QGIS can only use an integer field for this.


As below, mapserver identifies all the elements as strings, which is a 
problem. The data source is a Postgis table, the data statement 
generates an integer field to use to scale the layer, but mapserver 
seems to cast it as a string.


Is there any way to have mapserver specify a WFS integer element from a 
Postgis layer?


Brent,

I think you want to se the gml__type metadata item in the layer
to "integer".  You can read more detail on this in the WFS server document.
This should work in 5.6.

In MapServer trunk, as part of the OGR output overhaul, the ability was added
to put "gml_types" "auto" in the metadata in order to have the types derived
from the data source (for OGR, PostGIS, Oracle and shapefile input sources
for now).  The RFC on OGR output touches on this as well as the docs in
trunk.

The only difference I could detect is the coordinates within the Envelope. 

With PostGIS datasource it is:
 
-1.00 -1.00 
-1.00 -1.00

With MapInfo it is:

-1.00 -1.00 
409388.231116 5709944.987211

Even if the upperCorner is set, it is not the upper Corner of the 
featureCollection (4 features), that should be selected by the filter 
condition. And in both cases I did not change the EXTENT of the MAP und LAYER 
sections (EXTENT 389965 5693582 420177 5732815, "wfs_extent" "389965 5693582

So please let me know, if you have another idea to solve this problem
Tanks again!

Andreas, you may be without a wsf:Query element.  Here is a WFS 1.0.0 request

Y.A, a question for you:  I have thought that also the filters should be 
presented as gml3 with WFS 1.1.0 and thus posList should be used instead of 
coordinates. Am I wrong with this belief?  By the way, this is how Geoserver

Hi all,

As noted MapServer does not support gml:Surface. The original request with 
gml:Polygon seems to be correct.  
Andreas, is it possible to package it and send it to me off list. I can quickly 
check what the issue is.

This one may not be the only problem, but I would start by creating a valid WFS

[mapserver-users] querying to getting bounding box coordinates

[David Hildebrand]

I am running a WMS service with Mapserver in a Windows environment.  I
want to be able to run a non-spatial query on a parcel layer to return
the bounding box (in re-projected coordinates) for a particular parcel.
The bounding box and projection will then be used in a WMS query to
return a map image.

I've never coded server-side functionality with Mapserver so any
suggestions would be welcome.

Thanks to all.

Re: [mapserver-users] querying to getting bounding box coordinates

[Rahkonen Jukka]

Hi,

One alternative is to make first a WFS request with attribute filter for 
finding the feature and let the client to catch the bounding box from the 
result.
These examples should work, first is Geoserver and another Mapserver. The 
latter is pointing to a point layer and therefore I queried two features for 
getting a reasonable bounding box.

http://sigma.openplans.org:8080/geoserver/wfs?service=wfs&version=1.1.0&request=getfeature&typename=states&maxfeatures=1
http://188.64.1.61/cgi-bin/osm-mapserver_i?service=wfs&version=1.1.0&request=getfeature&typename=POI_pub_restaurant&maxfeatures=2

These are just crude examples without the property filter. Queries can be build 
also so that they do not return attributes. I hope you'll see the idea and 
think if it could make sense for your use case.

Re: [mapserver-users] querying to getting bounding box coordinates

[Rahkonen Jukka]

Hi,

Yes, they are WFS queries but you can send them to the same Mapserver service 
if you configure the mapfile properly. If you do not want to use WFS then I 
suppose you can do whatever you want with mapscript but that is something I do 
not know anything about. With some imagination it could be possible to do 
queries and get vectors out from WMS service and search the bounding box on 
client side (by using attribute filters inside SLD, or variable substitution 
inside DATA or FILTER, and by having KML as outputformat). Does not feel like a 
right way to do even it might be fun to experiment with. I suggest to read 
about mapscript http://mapserver.org/mapscript/index.html

[mapserver-users] Clipping returned WFS data to the requesting bounding box

[mattmendick]

Hi list-

I have some data that I'm getting at in MapServer via WFS that spans over
large areas, and my requesting region is always a bounding box that is
fairly small.  I would like to clip the returned data to the bounding box
that requested it in the first place and I have been successful in getting
back the proper clipped geometries, following the suggestions in this post:

http://osgeo-org.1803224.n2.nabble.com/Postgis-Intersection-on-requested-data-td1973165.html

The only problem is that the "describeFeatureType" and "getFeature" calls to
this layer do not return any record attributes.   I tried specifying them
using propertyName, but they still don't show up.  My DATA entry looks like
this:

DATA "the_geom FROM (SELECT ST_Intersection(f.wkb_geometry, !BOX!) AS
the_geom, f.* FROM flood as f) AS subquery USING UNIQUE ogc_fid USING SRID =
4326"

I've also tried specifying each attribute individually instead of using f.*
which yields the same results.  I understand that the form of the DATA entry
should be: 

[columntodraw] FROM [sourceofdata] USING UNIQUE [uniquekey] USING
SRID=[srid]

as was mentioned by Paul Ramsey in the previous post.

My understanding is that [sourceofdata] should be a dataset (either table
name or complete query like I've specified above) that has a geometry column
specified with [columntodraw] and then any attributes.  What am I missing?

Our fallback is to do clipping later when processing the data, but better to
use the very fast ST_Intersection() method I would say, if it's possible. 
Thanks!

RE: [mapserver-users] RE: querying to getting bounding box coordinates

[David Hildebrand]

I wanted to retain WMS compatibility but the WMS protocol does not seem
to support attribute queries.  I know I can use GetFeatureInfo to get
attributes including the bounding box of the feature because these are
CGI variables.  However, GetFeatureInfo uses a spatial query (an image
point).  If I use MapServer's mode=itemquery what would be the URL
syntax and the requirements on the server side?  Would I be able to
specify or determine the projection?

Thanks for your help.

RE: [mapserver-users] RE: querying to getting bounding box coordinates

[Lime, Steve D (DNR)]

There are 3 pieces to this:

1) in your mapfile you have to add validation for your query string to the 
layer metadata:

LAYER
  NAME 'testy'
  ...
  METADATA
...
qstring_validation_pattern 'some regex'
  END
END

and you have to define a template, I prefer the new-style templates via an 
output format:

OUTPUTFORMAT
  NAME 'bbox'
  DRIVER TEMPLATE
  MIMETYPE 'MIMETYPE 'text/html'
  TEMPLATE 'bbox.html'
END

2) now create the template (bbox.html):


[resultset layer="testy"]
[feature]
[shpext expand="20%"]
[/feature]
[/resultset]

(Note that in 5.6 you can set a few attributes in most extent-related tags to 
project and expand 
the output. This is very handy when getting extents to create other maps so you 
leave some space
around a feature.)

3) and finally a URL...

http://.../cgi-bin/mapserv?map=your.map&mode=itemquery&qitem=parcel_id&qstring=12345678&qlayer=testy&qformat=bbox

You could create templates more conducive to use with AJAX, perhaps JSON or 
XML. You have lots of control...

coordinates

Are you limited to WMS/WFS or can you use stock MapServer queries?
Passing in
a parcel id and returning it's bounding box is trivial using
mode=itemquery and
a template.

Subject: [mapserver-users] querying to getting bounding box coordinates

I am running a WMS service with Mapserver in a Windows environment.  I
want to be able to run a non-spatial query on a parcel layer to return
the bounding box (in re-projected coordinates) for a particular parcel.
The bounding box and projection will then be used in a WMS query to
return a map image.

I've never coded server-side functionality with Mapserver so any
suggestions would be welcome.

Thanks to all.
