Some of the new capabilities available with Dekho v3x utilise an ArcGIS Server Geometry Service, including functionality such as snapping, coordinate system readouts in multiple coordinate systems etc. As a result, an ArcGIS Server Geometry Service needs to be added to your primary instance of ArcGIS Server.
Step 01> Follow the steps set out in the section Publish the Geometry Service to create a geometry service if you do not already have one.
Step 02> Follow the wizard through to completion; the remaining defaults are acceptable for Dekho’s purposes.
Step 03> Once the Geometry Service has been created, in the Dekho Administration client, edit the settings and enter the url to the REST handler for the geometry service into the geometry.service setting, and save.
