Hello, be care full with QGIS layer CRS definitions. By default QGIS will assign WGS84 as layers CRS if layer lacks CRS definition or definition is bogus. Use ogrinfo -ro -so MyFile to check files CRS. Still IIRC DXF doesn't contain CRS definition - You have to look into metadata provided with Your DXF file (if You have metadata) or do Your best guess based on DXF data location (i.e. DXF file from Latvia most likely will contain data in LKS-92/TM CRS). If You are interested in transforming DXF ?? to UTM, You can also try to use ogr2ogr and then import result into GRASS for analysis/processing. ogr2ogr provides -s_srs option where You can specify source CRS.
Hope this helps, Maris. 2009/11/18, Raffaele Morelli <raffaele.more...@gmail.com>: > 2009/11/11 Micha Silver <mi...@arava.co.il> > >> Raffaele Morelli wrote: >> >> Hi you all, >> >> how can I transform a dxf (imported with v.in.dxf) layer in utm32 >> coordinates system?
