Re: [GRASS-user] v.in.ogr weird import
Hi Moritz, Let's go... What does g.proj -p show ? g.proj -p -PROJ_INFO- name : Latitude-Longitude datum : wgs84 towgs84: 0.000,0.000,0.000 proj : ll ellps : wgs84 -PROJ_UNITS unit : degree units : degrees meters : 1.0 Are the shapefiles accompanied by .prj files ? Yes. And they look like this: GEOGCS[GCS_WGS_1984,DATUM[D_WGS_1984,SPHEROID[WGS_1984,6378137,298.257223563]],PRIMEM[Greenwich,0],UNIT[Degree,0.017453292519943295]] And the g.proj output of a vector is: g.proj -p Tracklines2.shp Trying to open with GDAL...ERROR 4: `Tracklines2.shp' not recognised as a supported file format. Trying to open with OGR..succeeded. A datum name wgs84 (WGS_1984) was specified without transformation parameters. Note that the GRASS default for wgs84 is towgs84=0.000,0.000,0.000. -PROJ_INFO- name : Lat/Lon proj : ll datum : wgs84 a : 6378137 es : 0.006694379990141316 no_defs: defined -PROJ_UNITS unit : degree units : degrees meters : 1.0 And after import this data with v.in.ogr, I see: At v.info I see: | Projection: UTM (zone 0) | |N: -9.053S: -10.666 | |E: -78.787 W: -80.817 | |B: 0.000 T: 0.000 | The weird part comes now... 1) My locations show this Projection: UTM for any vectors imported, but the location is on Lat-Long. 2) This same location when opened at GRASS 6.3 (Windows) show the projection correctly for these rebel vectors 3) GRASS 6.3 (Windows) also can import the shapefiles in the right way, but if I take the location back to Linux, the is problem back. Maybe I have a plataform issue. I tried this (importing data at my GRASS 6.3 Linux): 1) import shapefiles created at QGIS; 2) (re)reproject my shapefiles with ogr2ogr; 3) created a location based in a shapefile (with prj file) None worked. Actually my vectors work fine (I tried display and some analysis), but they are weird... because they have a Lat-Long extent, but show an UTM projection. Best regards, Christian S.

Re: [GRASS-user] v.in.ogr weird import
Thank you guys, but this I already know... my case is something more weird. Maybe is because I was messing around with r.shaded.relief (which formally is suppose to work just with UTM locations, maybe my gisdatabase is now confused... I don't know. With our without -o, v.in.ogr still import the lat-long data translate them (while importing) to UTM projection. And the path for the SHP is right, since I am using the graphical interface... so, no chance to make mistakes.
