I am new GRASS use, and learning GRASS to use conservation literacy using
rare plant databases. To start with I converted a Kml file of the state of
Meghalaya India to a shapefile using DNRGarmin. However when I try to open
the shapefile in GRASS I keep getting errors and the map of the opened file
does not look anything like the original map. What did I do wrong. I am
attaching the shapefile and dbf file, I used.
thanks in advance
