Q: How can I determine the number of overlapping features per location after import of SHAPE file?
A: You can run this (example):
v.in.ogr dsn=./shp/ layer=fireHistory output=fireHistory v.category input=fireHistory output=tmpFire v.db.addtable map=tmpFire table=tmpFire_2 layer=2 columns='num,int' v.to.db map=tmpFire layer=2 qlayer=1 option=query col=num qcol='count(*)' type=centroid # Export it to a raster layer: v.to.rast input=tmpFire layer=2 output=mf use=attr column=num
