DESCRIPTION

v.gsflow.mapdata allows the user to add attributes from any raster or vector (area or point) data set to a GSFLOW set of HRUs, MODFLOW grid cells, gravity reservoirs, stream segments, or stream reaches. It does so by using either an averaging or a nearest-neighbor approach, depending on the type of both the data source geometry (raster, vector area, vector point) and, if it is a vector, the data source in the column (integer, string (varchar), or float (double precision)).
Nearest-neighbor (v.distance,) is used for:
Vector point data
Vector area data in which the data type in the column that is queried is integer or varchar
An average (v.rast.stats,) is used for:
Raster data
Vector area data with data in the column that is queried that is of "double precision" type
