<em>r.series.interpol</em>
-interpolates raster maps which are located temporal or spatial in between existing input raster maps.
+interpolates new raster maps located temporal or spatial in between existing raster maps.
The interpolation is performed at specific sampling positions. The sampling position for each output map must be specified.
Sampling positions are always located in the normalized intervall (0;1).
The following interpolation methods are supported.
