About GCD Software

GCD 7 is available as two 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 AddIn for ArcGIS

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.

GCD Standalone

The GCD Standalone version lets you:

  • Create projects
  • Specify DEM surveys
  • Perform change detection
tip

GCD Standalone does not include a map display. Ideal for those using QGIS or other GIS software.

Key Features

  • 64-bit application (faster than 32-bit AddIn)
  • No ArcGIS required
  • Uses ClickOnce technology:
    → Installs to your profile folder
    → No admin rights needed
    → Follow prompts carefully when downloading .exe

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
