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.
