Project Task Activity


Applies a geographic projection to a collection of graphics using the ArcGIS Geometry Service.

Inheritance Hierarchy:



This activity will take a collection of graphics and apply a geographic projection onto them. You can use this activity to transfer graphics between projection systems.

In a Workflow:

If your data is in a specific projection for the area your business focuses on, but you then you need to access a layer or service like geocoding that covers a broader geographical region using a different projection, you could use the Project Task activity to convert those results/data to your operation projection.
