Notes about the GCP file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The GCP file type is primarily associated with 'Ground Control Point File'. Ground Control Point file used in image processing of remote sensing data often to form map projections. CHIPS (CopenHagen Image Processing System) uses these files.
