Hi, I've been following the procedure at http://grass.osgeo.org/wiki/Import_XYZ to import DEMs into GRASS.
It has worked for two DEMS, but I have a problem with the third one at the step where one "verifies that the number of rows in the ASCII file corresponds to the number of cells in the enlarged region". At this point, g.region reports 1146474 cells in the region, while I have 1146370 lines of coordinates in my file. The output of g.region is: ----- projection: 99 (Transverse Mercator) zone: 0 datum: ** unknown (default: WGS84) ** ellipsoid: wgs84 north: -49312.49 south: -74587.5 west: -3015862.5 east: -2987512.5 nsres: 25.00000989 ewres: 25 rows: 1011 cols: 1134 cells: 1146474 ----- The first three and last three coordinates in my text file are: ----- -74575.000000,-3015850.000000,1548.830000 -74575.000000,-3015825.000000,1548.330000 -74575.000000,-3015800.000000,1547.500000 . . . -49324.990000,-2987575.010000,1510.980000 -49324.990000,-2987550.010000,1511.240000 -49324.990000,-2987525.010000,1511.470000 ----- Can someone help me to figure out what's going on?
