GIS to GRASS command translation

Translation Quick Reference Table

GIS Software/Module	GIS command/feature	GRASS command(s)
ESRI ARC-INFO/ARC	LATTICESPOT	v.what.rast

GIS command/feature	GRASS command(s)
LATTICESPOT <in_lattice> <in_cover> {spot_item} {z_factor}	v.what.rast vector=<in_cover> raster=<in_lattice> layer=layer column={spot_item}

Discrepancies:

{spot_item} defaults to "SPOT" for LATTICESPOT, but must be explicitly defined for v.what.rast
{z_factor} must be applied to the GRASS vector database after-the-fact.
LATTICESPOT performs a bilinear interpolation to assign raster values to the output vector, whereas v.what.rast uses nearest neighbor.
