About GCD Software

GCD 7 is available as three separate products:

  • GCD Standalone is independent of ESRI and does not require ArcGIS. It has no built-in map display, but is otherwise fully functional.
  • GCD AddIn for ArcGIS Pro for read only display of GCD project data in ArcGIS Pro.
  • GCD AddIn for ArcGIS 10.x fully functional GCD version that includes all of Standalone plus map display.

GCD Standalone

The latest GCD release for ArcGIS Pro version 3.4 and higher. This is a limited version capable of displaying spatial GCD data in ArcGIS Pro. This version is read only and does not create or alter GCD projects.

GCD 7 also has a legacy version for ArcGIS 10.4 and higher. This is a fully operational version of GCD that combines both map display as well as full functionality to create and manipulate GCD projects.

Prerequisites

The GCD Standalone version requires .NET Framework 4.5.2 (that should already included with Windows 10).

The GCD AddIn for ArcGIS Pro requires .NET Framework 8 as well as ArcGIS Pro 3.4 or higher.

Other Notes

  • Incompatibility: GCD 6 and 7 projects cannot be opened across versions.
  • Running Both Versions: AddIn and Standalone can coexist. The only shared resource is the FIS Library. You can use both on the same *.gcd file. Details

Tutorials & Extensions

To build surfaces in ArcGIS, you need Spatial Analyst and 3D Analyst extensions enabled. You do not need these extensions, or indeed any GIS at all, to use the GCD standalone. The standalone performs all it's own geoprocessing internally.
