Landsat multispectral ratio images Red Sea Sudan
2015/12/29
The Red Sea Hills Region is a vast span of rugged, harsh and inhospitable sector of the Earth with inimical moon-like terrain, nevertheless since ancient times it is famed to be an abode of gold and w...
The Research and Design of the Base-height Ratio for the Three Linear Array Camera of Satellite Photogrammetry
Three linear Array CCD camera Satellite photogrammetry Space intersection angle
2015/11/23
In the satellite photogrammetry, the base-height ratio greatly impacts the elevation accuracy of the targets for the plotting map, and the greater base-height ratio, the higher elevation precision. Th...
"atmospheric" correction of digital colour images based on luminance ratio consideration
Photogrammetry Digital Technology Colour Imagery Atmosphere Correction
2015/9/1
Colour images change their appearance with increasing flying height: they are affected by an increasing bluish tint. This phenomenon is primarily the result of Rayleigh scattering. Considerations conc...
