I am trying to reproject all data to a single projection: Albers Equal Area (NAD83) and g.region is:
projection: 99 (Albers Equal Area) zone: 0 datum: nad83 ellipsoid: grs80 north: 43 south: 34 west: -121 east: -112 nsres: 1 ewres: 1 rows: 9 cols: 9 cells: 81 The DEMs were originally in lat/lon (NAD83) and imported to that location. When I try to reproject them I see that the regions do not match. For example: GRASS 6.5.svn (Nevada-aea):~/grassdata > r.proj in=dem_area15 location=Nevada-ll mapset=PERMANENT method=cubic_f Input Projection Parameters: +proj=longlat +no_defs +a=6378137 +rf=298.257222101 +towgs84=0,0,0,0,0,0,0 Input Unit Factor: 1 Output Projection Parameters: +proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=23 +lon_0=-96 +x_0=0 +y_0=0 +no_defs +a=6378137 +rf=298.257222101 +towgs84=0,0,0,0,0,0,0 Output Unit Factor: 1 ERROR: Input raster map is outside current region Running r.proj -p produces: GRASS 6.5.svn (Nevada-aea):~/grassdata > r.proj -p in=dem_area15 location=Nevada-ll mapset=PERMANENT method=cubic_f Input Projection Parameters: +proj=longlat +no_defs +a=6378137 +rf=298.257222101 +towgs84=0,0,0,0,0,0,0 Input Unit Factor: 1 Output Projection Parameters: +proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=23 +lon_0=-96 +x_0=0 +y_0=0 +no_defs +a=6378137 +rf=298.257222101 +towgs84=0,0,0,0,0,0,0 Output Unit Factor: 1 Input map <dem_area15@PERMANENT> in location <Nevada-ll>: Source cols: 3600 Source rows: 3600 Local north: 2064411.8954923 Local south: 1973182.43184852 Local west: -1787211.15607592 Local east: -1679987.035036 Is this a result of user error? If so, do I re-import these data? If not, what do I need to do to get all these data into a single location?
