Ground control points (GCPs) are surveyed reference points with known real-world coordinates, used to align a Hovermap scan to a specific coordinate system. Applying GCPs ensures the point cloud matches the same coordinate reference as other datasets, such as survey data, mine plans, or existing site models.
The articles in this section cover the two main tasks:
Process scan data with Ground Control Points (GCPs). Apply GCPs during processing to georeference a scan to a known coordinate system.
Check Points. Use additional surveyed points to verify the accuracy of a GCP-aligned scan.
