transformation, Histogram stretching, IHS transformation to RGB, Image
rectification (affine and polynomial transformations on raster and
vector targets), Ortho photo rectification, Principal component analysis

<p class="MsoNormal">I can acquire some DigitalGlobe imagery (Quickbird, Worldview -01 and 02, Geoeye and the upcoming Worldview 03) in various formats (ntf or jpeg). Is it possible to download and view those on Grass GIS? Will it permit zoom, pan and edge
contrast and brightness enhancement of the image? Does Grass have any mensuration capabilities for a downloaded satellite image? Thanks. Ciao dj
