Determining the Optimum Number of Ground Control Points for Obtaining High Precision Results Based on UAS Images

open access: yes, 2018
Ground control points (GCPs) are used in the process of indirectly georeferencing Unmanned Aerial Systems (UAS) images. A minimum of three ground control points (GCPs) is required but increasing the number of GCPs will lead to higher accuracy of the ...

Why you need to use ground control points (GCP) for drone mapping

open access: yesGEOmedia
The article explains why Ground Control Points (GCPs) remain essential in drone mapping, even with the advent of RTK/PPK drones. GCPs act as reliable reference markers that correct positional errors, ensuring that aerial imagery aligns accurately with ...

Integration of tie-points in digital mosaicking

open access: yes, 1988
Current mosaicking methods generally use Ground Control Points or GCF's (points known in ground— as well as image-coordinates) to separately resample all the original images to a common ground coordinate system, and then merge these new images into one ...

GCP Placement Methods for Improving the Accuracy of Shoreline Extraction in Coastal Video Monitoring

open access: yes한국해양공학회지
In coastal video monitoring, the direct linear transform (DLT) method with ground control points (GCPs) is commonly used for geo-rectification. However, current practices often overlook the impact of GCP quantity, arrangement, and the geographical ...

Optimizing photogrammetric DEMs for glacier volume change assessment using laser-scanning derived ground-control points

open access: yes
Photogrammetric processing of archival stereo imagery offers the opportunity to reconstruct glacier volume changes for regions where no such data exist, and to better constrain the contribution to sea-level rise from small glaciers and ice caps.
