Dear GDAL people: Using DSM, I want a "shadow map" not only by the slope itself but also by the other slopes. I mean, if a tall and steep peak exists, and if it is illuminated by the sun from near the horizon, the shadow of the peak falls on a wide area of the foot of the mountain. Such shadow is normally not estimated by a simple "hillsahde" algorithm, which includes the "gdaldem" command. I want to map such shadows as well as the normal "hillshade" shadows.
If you know a library or command to help it, please let me know!! -- Kenlo Nishida Nasahara Faculty of Life and Environmental Sciences University of Tsukuba, Japan 305-8572 [email protected] _______________________________________________ gdal-dev mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/gdal-dev
