Role of Ground Control Points (GCPs) in Integration of Terrestrial Laser Scanner (TLS) and Close-range Photogrammetry (CRP)

, 2019
The need for GCPs is increasingly more important with the increase in higher accuracy requirements and increase in user expectations. GCPs (Ground control points) are necessary for orientation and placement of photographs and 3D models in the spatial coordinate system, and they play a key role in co-registration of two point clouds.

Extraction of ground control points (GCPs) from synthetic aperture radar images and SRTM DEM

International Journal of Remote Sensing, 2006
Qualified ground control points (GCPs) are crucial in the geolocation of a remotely sensed image. If a region has no published map, the geographical coordinates of GCPs must be obtained indirectly. Although these can be re‐constructed from a synthetic aperture radar (SAR) image using sensor position and velocity, this conventional method does not ...

Comparative Study of UAV Mapping with and without Ground Control Points (GCPs)

International Journal of Geoinformatics
Unmanned Aerial Vehicles (UAVs) have transformed geospatial data acquisition, yet the necessity of Ground Control Points (GCPs) for spatial accuracy versus operational efficiency remains a critical topic of investigation. This study presents a comparative analysis of UAV mapping accuracies achieved with and without the integration of GCPs. Conducted at

USING GROUND CONTROL POINTS (GCP) AND UAV POIND CLOUD PROCESSIN� IN WATER MANAGEMENT

SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings, 2022
Using aerial vehicles without pilot (UAV-unmanned aerial vehicle) or Drone has seen a rapid development, over the last decade, in order to obtain spatial information of the Earth's surface. This scientific paper was realized for the Hydrotechnical Node of Costei, from Timis County and has as purpose the processing of aerial images, obtained from a ...
