Syntax

<TOCOORDSYS	Attribute Description Table
When using ArcMap Server:      (r)id="integer"      (r)string="string"      When using Query or Feature Server:      (r)id="integer"      (r)string="string"      datumtransformid="integer"      datumtransformstring="string" >      No Child Elements </TOCOORDSYS >
(r): Attribute or child element is required.

Description

The coordinate system of the geometry to project to when using GET_PROJECT.

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 FROMCOORDSYS, , 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 TOCOORDSYS, 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.
