I have made a geoprocessing service which retrieves data from my enterprise geodatabase. My geometries are stored in wgs 84 srid (4326), but i need my data to be returned with a different spatial reference, since I want to use them in a graphics layer, and as I know graphics layer in not reprojected on the fly.

  • Can you edit the geoprocessing model itself? That would be the best way to do it. – Devdatta Tengshe Jan 12 '15 at 9:09
  • @Devdatta Tengshe yes I can. I am the one implementing it. But in that case I would prefer the the srid that I want my data to be convrted in, to be a parameter passed from my client. So my service would return data that could conform to any spatial reference of any basemap. – Smalis Jan 12 '15 at 9:20
  • you could try with project_management, but this is a bit risky with any type of projection, because the user would also need to specify the transformation when needed otherwise the projection will be inaccurate. – radouxju Jan 16 '15 at 7:39

Have you seen output spatial reference on the geoprocessing endpoint itself? https://developers.arcgis.com/javascript/jsapi/geoprocessor-amd.html#outspatialreference and Output spatial reference (coordinate system)

If you are doing it in arcpy, then I think you are looking for Project (Data Management):

arcpy.Project_management (in_dataset, out_dataset, out_coor_system, {transform_method}, {in_coor_system})

For model based geoprocessing services, I think there is an alternative, but you might be able to just wrap this into one.
