Translation Discussion
ESRI ARC-INFO
LATTICESPOT
| 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.
