I'm working on watershed hydrology, then I went to obtain drainage direction, accumulation zones, streams system and elementary watersheds of a study area. However I work on an area which belong to 2 EPSG (EPSG 3313 and EPSG 2972).
I download all the SRTM tiles of the study area and have filled the voids. I merged these tiles and projected the result in the EPSG 2972 (initially WGS84). Of course, a part of the DTM has negative EAST coordinates which cause errors when assinging region and running r.watershed and r.water.outlet. I tryed to work in WGS84 but still r.water.outlet does not work. Is it possible to define a region with two EPSG? How achieve r.water.outlet with success I'm quite locked...Any help ? ------------------------------------------------------------------------------------ B.Mourad Laboratoire de Mathématiques Informatique et Applications Université de Guyane Tél : 06 63 81 50 29 _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
