Description:

The current coordinate system of filters in the requesting client.

Restrictions:

• Must use either id or string, but not both.
• For datum transformations either datumtransformid or datumtransformstring is used, but not both.
• In ArcMap Image Services, datumtransformid or datumtransformstring are not valid.

Notes:

• For a complete list of supported IDs and definition strings, see:
  • Projected Coordinate Systems Listing [Sorted by projection ID] [Sorted by name]
  • Geographic Coordinate Systems Listing [Sorted by projection ID] [Sorted by name]
  • Datum Transformation Listing [Sorted by projection ID] [Sorted by name]
  
  
• When using definition strings, the quotes in the string must be changed to " so the ArcIMS Spatial Server can interpret the string correctly. For example, the definition string for World Mollweide is:
  
  PROJCS["World_Mollweide",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Mollweide"],PARAMETER["False_Easting",0],PARAMETER["False_Northing",0],PARAMETER["Central_Meridian",0],UNIT["Meter",1]]
  
  Once the quotes have been changed, the string looks like this:
  
  PROJCS["World_Mollweide",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Mollweide"],PARAMETER["False_Easting",0],PARAMETER["False_Northing",0],PARAMETER["Central_Meridian",0],UNIT["Meter",1]]
  
  
• The attributes datumtransformid and datumtransformstring are used when datum transformation information needs to be included. Only datum transformations to and from WGS 1984 are supported.
  • When these attributes are used with COORDSYS and FILTERCOORDSYS, the datum transformation is from a non-WGS 1984 datum to WGS 1984. For example, Pulkovo_1942_To_WGS_1984 (datumtransformid="8157") transforms data from Pulkovo 1942 to WGS 1984.
  • When these attributes are used with FEATURECOORDSYS, the datum transformation is from WGS 1984 to a non-WGS 1984 datum. In the above example, the datum transformation is from WGS 1984 to Pulkovo 1942.
• If FEATURECOORDSYS is used, then FILTERCOORDSYS must also be included.
• If a service with FILTERCOORDSYS is used in the ArcIMS HTML Viewer, ArcIMS Java Standard or Custom Viewers, or ArcExplorer 4, FEATURECOORDSYS and FILTERCOORDSYS must use the same value for id or string.
• If a layer does not project, double check that a *.prj file or ArcSDE spatial reference table exists for the layer. If not, COORDSYS must be included with the layer.
• For more information on the projection elements, see Using Projection Elements.
