How to use custom transformations with geoprocessing services in ArcGIS Server

The custom geographic transformation files are created in ArcGIS Desktop using the Create Custom Geographic Transformation tool. The file is saved in the Profile folder of the current login with the extension .gtf.

The file paths are similar to the following:

• ArcGIS version 10:

C:\Users\<user name>\AppData\Roaming\ESRI\Desktop10.0\ArcToolbox\CustomTransformations\MyCustomTransformation.gtf

• ArcGIS version 9.3.1:

C:\Users\<user name>\AppData\Roaming\ESRI\ArcToolbox\CustomTransformations\MyCustomTransformation.gtf

Once this is created the current login user can author a model using the custom geographic transformation in the 'Project' and 'Project Raster' tools in ArcGIS Desktop.

If the model is to be published to ArcGIS Server, the custom transformation file must be copied to the ArcGIS Server machine for the geoprocessing service to use. The location is the ArcGIS server object container account's Profile folder with the following folder structure:

On Windows

• ArcGIS version 10:

C:\Users\ArcGISSOC\AppData\Roaming\ESRI\Server10.0\ArcToolbox\CustomTransformations\MyCustomTransformation.gtf

(Where ArcGISSOC is the default name of the ArcGIS server object container account.)

• ArcGIS version 9.3.1:

C:\Users\ArcGISSOC\AppData\Roaming\ESRI\ArcToolbox\CustomTransformations\MyCustomTransformation.gtf

On Linux

• ArcGIS version 10:

/sslrh51/arcsvr10/.arcgis10.0/Application Data/ESRI/Server10.0/ArcToolbox/CustomTransformations/MyCustomTransformation.gtf

(Where arcsvr10 is the GIS user account name.)

• ArcGIS version 9.3.1:

/sslrh51/arcsvr931/Application Data/ESRI/ArcToolbox/CustomTransformations/MyCustomTransformation.gtf
