Dear lists, I need to import the map available here (http://geodata.grid.unep.ch/mod_download/download_geospatial.php?selectedID=2150&newFile=download/Nightlights_2003_tif.zip) to GRASS. The map is in Tiff format and appears fine in QGIS, but when I import it to GRASS (with r.in.gdal) it becomes a very narrow N-S stripe.
Here's the raster info that QGIS gives me on this map: - - - Driver: GTiff/GeoTIFF Files: /media/disk/MARCIA/dadosExternos/variaveis/UNEP/nightLights/N_Light_2003.tif /media/disk/MARCIA/dadosExternos/variaveis/UNEP/nightLights/N_Light_2003.aux /media/disk/MARCIA/dadosExternos/variaveis/UNEP/nightLights/N_Light_2003.rrd Size is 43201, 15601 Coordinate System is: GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433], AUTHORITY["EPSG","4326"]] Origin = (-180.004166669999989,65.004166670000004) Pixel Size = (0.008333333300000,-0.008333333300000) Metadata: TIFFTAG_SOFTWARE=IMAGINE TIFF Support Copyright 1991 - 1999 by ERDAS, Inc.

I'm using QGIS 1.5 with the GRASS plugin, and tried both under Ubuntu and Windows. I tried also having someone save it as ASCII and importing with r.in.arc, but the result was always the same. Any ideas about what might be causing this? Anyone can manage to import this map to GRASS correctly? Thanks for any help, Márcia _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
