I have to import data vector and raster into GRASS GIS database. I try several projections and I don't know why I can't display the data in Grass GIS. But I can display my data with the grass plugin in QGIS...

    Can you provide a link to the data (or a subset) so I can try it? Are there any error messages?

  • I have no problem loading and displaying both datasets in GRASS 7.1 (using EPSG:4326.) Is the region correctly set to the extent of your data? You can force this when you import by checking "Extend region extents based on new dataset" in the import dialog.

As stated in your comment, the upgrade to GRASS GIS 7 helped - a lot has been invested to simplify the usage (more to come!). Be sure to consider for raster data the computational region, however, this is easily done via right mouse button in the map layer manager.

Note that you can create a GRASS GIS location directly from the data set: http://grasswiki.osgeo.org/wiki/GRASS_Location_Wizard This will be further simplified in the next version.
