Target Influence on Ground Control Points (GCPs) Identification in Aerial Images
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020 Unmanned aerial vehicles (UAVs) are used nowadays as a standard tool to derive very high-resolution geospatial data. However, UAV payload limitation imposes the use of not such reliable hardware affecting the georeferencing precision. In the literature it is possible to find numerous studies investigating the parameters influencing UAV-based products ...

Extraction of ground control points (GCPs) from synthetic aperture radar images and SRTM DEM
International Journal of Remote Sensing, 2006Qualified 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 ...

Extraction of ground control points (GCPs) from synthetic aperture radar image using DEM
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004Synthetic aperture radar (SAR) data have serious geometric distortions caused by inherent side looking geometry and are usually corrupted by speckle noises so that it is difficult to identify ground control points (GCPs). The location of the pixel in a given SAR image can be derived from the knowledge of sensor position and velocity.

An automatic ground control point matching based on GCP chip database for remote sensing images
2009 International Conference on Image Analysis and Signal Processing, 2009With the rapid development of remote sensing technology and comprehensive applications, there are more demands on precision and efficiency for remote sensing digital orthographic maps (DOM). Selecting and positioning ground control points (GCP) is one of the most important parts of geometry correction to produce the DOM.
