Raster Interpolation is a QGIS plugin to interpolates values on raster layers.
It browses a vector layer of points, interpolates at their position the value of a raster layer and save the value in a chosen field of the vector layer.
Interpolation can be nearest, linear or bi-cubic. Simple filter on the vector layer may be applied (browse only currently NULL values and/or only selected features). It can be used to calculate elevation from a DTM.
- The raster layer and the vector layer must have the same CRS (coordinate reference system).
- The vector layer mustn't be a (PostGIS) multipoint layer.
- Interpolation: nearest neighbot, linear or bicubic* interpolation
- Process can be limited to a selection or to yet undefined values
- Choose band to process in the raster
