I found tool "Tools for point layer (Herramientas para capas de puntos)/
Interpolate Raster (Muestrear capa raster)" in SEXTANTE, it is similar to
"Surface Spot" of ArcGis, I need to found it, in Grass GIS 6.40ORC6, but I can
not.
The tool interpolates heights for points in a feature class from a surface (ex:
DTM). The point heights (interpolate heights) are stored in a field that's
added to the input feature class.
Thank you for your answer
