I was able to successfully compile a small area using ASTER tiles. The resulting map looked correct.
Hi Christian, I did more testing using the complete ASTER tile ASTGTM_N49E008_dem.tif. I received a lot of index out of bounds exceptions in methods markEdge and traceByStepping. In all cases iy and p.iy were -1. Since I didn't understand the context of the complete source code, I just added checks to ensure that array "visited" was not accessed for these values. This allowed the contour lines to be compiled. Do these errors result from bad ASTER data? You may wish to consider updating your patch to handle this condition. Cheers.
