Importing data
Getting your data into GRASS
GRASS supports many common GIS formats, and many uncommon ones too.
The primary import/export tool is called GDAL/OGR.
Create a location for your data with the correct map projection using the Location Wizard on the main startup screen, then in the menus:
Raster formats use File -> Import using GDAL Vector formats use File -> Import using OGR
After the map has been imported you can add it to the display layer list in the Layer Manager window. You will most likely want to right click on the map in the layer list and select "Zoom to selected map(s)". Otherwise when you go to view the map you could be far away and just see a white display canvas.
The "computation region" is a very important concept in GRASS. You can read about it in the rasterintro help page. You can set the computation region and cell resolution to match a specific map with the g.region module.
