Hi,
it seems that terraflow could handle only and exatly only the situation when g.region raster=*sourcedtm* *Is it true?* I tried to script setting g.region to raster and then limit extent changing to a smaller sub-portion of the image. Full image: (g.,region raster=....) projection: 99 (HD72 / EOV) zone: 0 datum: towgs84=52.17,-71.82,-14.9,0,0,0,0 ellipsoid: grs67 north: 370558.27203605 south: -22830.24409709 west: 409913.84498418 east: 981298.29128666 *nsres: 9.99996228ewres: 10.00007782* rows: 39339 cols: 57138 cells: 2247751782 Partial region: projection: 99 (HD72 / EOV) zone: 0 datum: towgs84=52.17,-71.82,-14.9,0,0,0,0 ellipsoid: grs67 north: 213209.19577188 south: 193529.27000484 west: 488723.80321904 east: 508433.95660226 *nsres: 9.99996228ewres: 10.00007782* rows: 1968 cols: 1971 cells: 3878928 Is there any hope? Beyond Star Wars IV? thanks Robert
