The Imagery TODO list is the following: - merge of image libraries: A) - lib/imagery/: standard lib, in use (i.* except for i.points3, i.rectify3) - imagery/i.ortho.photo/libes/: standard lib, in use (i.ortho.photo, photo.*) B) - lib/image3/: never finished improvement which integrated the standard lib and the ortho lib. Seems to provide also ortho rectification for satellite data (i.points3, i.rectify3) - image modules: - merge of i.points, i.vpoints, i.points3 - merge of i.rectify and i.rectify3 - addition of new resampling algorithms such as bilinear, cubic convolution (take from r.proj?) - add other warping methods (maybe thin splines from GDAL?) - implement/finish linewise ortho-rectification of satellite data - Add support for > 8bit colors (only 0-255 supported currently) Relevant for you is this: - "implement/finish linewise ortho-rectification of satellite data" ...unfortunately stuck since GRASS 4/5... > I suppose it's done since > LANDSAT-TM need geometric correction and, all GRASS book refers to LANDSAT > images. (A part of the book refers to LANDSAT.) It would be great to see the existing algorithms integrated.
