[mapserver-users] [EXTERNAL] WMS GetFeatureInfo and Oracle 3D geometries

[Andrew.Parry at bentley.com]

Michael,

I wonder if you would be able offer some more advice on this. I have a version of mapserver compiled with the POINT_Z_M option.
Despite my best efforts, the geometry always returns in 2D. Do you happen to have an example map file entry and GetFeatureInfo call example?
Information from my config given below.

Thanks,
Andrew


mapserv -v
MapServer version 6.4.1 OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WFS_SERVER SUPPORTS=FASTCGI SUPPORTS=POINT_Z_M INPUT=JPEG INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

My map file includes this output format

  OUTPUTFORMAT
                  NAME "OGRGML"
                  DRIVER "OGR/GML"
                  FORMATOPTION "STORAGE=filesystem"
                  FORMATOPTION "FORM=multipart"
                  FORMATOPTION "FILENAME=result.gml"
  END


Layers include this metadata definition

    METADATA
      "wms_title"            "ESU"
      "wfs_title"            "ESU"
      "wfs_featureid"        "NE_ID"
     "gml_featureid"        "NE_ID"
      "wfs_enable_request"   "*"
      "wms_enable_request"   "*"
      "gml_include_items"    "all"
                  "wfs_getfeature_formatlist"  "OGRGML"

                  "ows_geometry"                           "LineString25D"
                  "wfs_geometry"                            "LineString25D"
    END

Andrew,

This is possible. You do need to do several things.


  1.  Mapserver needs to be compiled with USE_POINT_Z_M
  2.  You need to use an OGR output format
  3.  You need to define the output as a 2.5D geometry type, eg, if its a point then define the ows/wfs_geometry type as Point25D. See mapserver.org/output/ogr_output.html for more info

Hi,

I'm looking for a way to have GetFeatureInfo return three dimensions (x,y,z) from an Oracle spatial data source.
Right now it is returning 2D as GML. The z value contains a measure that is required to determine direction for distance calculations in the client (OpenLayers).
Any suggestions welcome.

Regards,
Andrew
