Q: How can I determine the number of overlapping features per location after import of SHAPE file?
A: You can run this (example) - note that it won't work with the DBF driver but requires SQLite, PostgreSQL, MySQL, or... driver:
v.in.ogr dsn=./shp/ layer=fireHistory output=fireHistory v.category input=fireHistory output=tmpFire type=centroid v.db.addtable map=tmpFire table=tmpFire_2 layer=2 columns='cat int' # Export it to a raster layer: v.to.rast input=tmpFire layer=2 output=mf use=attr column=num
