Automatic relocation of ground control points in Landsat imagery†

International Journal of Remote Sensing, 1983
Abstract Images obtained from the Landsat multispectral scanner are not provided in any normally recognized map projection system, so it is often necessary for a transformation to be made. This is usually done with the aid of ground control points, whose locations on the ground (or on a map)are accurately known and which can be accurately located ...

SAR ground control point identification with the aid of high resolution optical data

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Only until recently, it has been demonstrated that absolute localization with centimeter accuracy can be achieved for manually matched Persistent Scatterer (PS)s from TerraSAR-X images acquired from cross-heading geometries [1]. This paper describes an automatic algorithm for absolute localization of natural PSs in SAR images, where the detection of ...

Ground control pointing and geometric transformation of satellite imagery

International Journal of Remote Sensing, 1986
Abstract LANDSAT imagery has been corrected for Earth curvature and rotation, satellite attitude errors and sensor non-linearities, it still contains significant geometric distortions with the centre of the scene only located to an accuracy of a few kilometres.

A method for InSAR phase-offset calculation without using ground control points

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
Synthetic Aperture Radar Interferometry (InSAR) allows the generation of Digital Elevation Models (DEMs) exploiting the phase difference (interferogram) of SAR data pairs relevant to the same illuminated area and received by slightly different look angles. Within the processing chain leading from the acquired SAR data pair to the final InSAR DEM, it is

Invariant models for ground control points in high resolution images

International Journal of Remote Sensing, 1998
This paper addresses the problem of automatic identification of ground control points (GCPs) in high resolution satellite digital images. The method is based on characteristics of GCPs and their neighbourhood, invariant with respect to rotation and contrast change.
