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 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.
