Description:

Uses the ArcGIS Geometry Service to calculate the shortest distance between two geometries.

Inheritance Hierarchy:

System.Object
  System.Activities.Activity
    System.Activities.CodeActivity
      Geocortex.Workflow.Activities.DistanceTask

Function:

This activity computes the shortest distance between geometries using the specified units.

Geodesic

Calculate distance based on a geodesic coordinate system.

Geometry 1

The geometry from where the distance is to be measured.

Geometry 2

The geometry to which the distance is to be measured.
