Project Single Geometry Task Activity

Description:

Applies a geographic projection to a single geometry using the ArcGIS Geometry Service.

      Geocortex.Workflow.Activities.ProjectSingleGeometryTask

Function:

This activity takes a single geometry and applies a geographic projection onto it. You can use this activity to transfer a geometry between projection systems.

In a Workflow:

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

Properties:

Name	Description
In Arguments
Credentials	The network credentials that are sent to the host and used to authenticate the request.
Custom Parameters	Additional parameters to include in the request.
Datum Transform	The datum transformation to use.
Disable Client Caching	If true, adds a timestamp parameter (_ts) to the request to prevent it from being loaded from the application's cache.
Geometry	The geometry to project. The geometry must have a spatial reference.
Geometry Service Url	The URL of the ArcGIS Server Geometry service. For example: `http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer.`
Proxy Url	The URL to proxy the request through.
Spatial Reference	The spatial reference to project the geometry to.
Token	The token needed to access a secure ArcGIS task.
Transform Forward	A value indicating whether the datum transformation is in the forward or reverse direction. Must be used in conjunction with Datum Transform.
Misc
Display Name	ProjectSingleGeometryTask You can change the name of an activity to one that describes what it does. A descriptive name can make a workflow easier to interpret and maintain.
Out Arguments
Result	The result geometry projected into the new spatial reference.
