GiD_Raster create|interpolate
To create from the mesh a raster (2D grid) with a value that represents the z, and use a raster to efficiently interpolate values to other points or all points of other raster.
...
If cellsize is 0.0an automatic value is used
far_points_set_nodata 0 or 1
GIS::GetRasterFromNodes { selected_node_ids cellsize far_points_set_nodata far_points_distance }
It returns a raster from the selected mesh nodes. selected_node_ids is expected sorted increasing.
...
far_points_set_nodata 0 or 1 (and far
if 0 all grid points will have interpolated value, 1 far grid points will be set with special nodata (usually -9999) value
far_points_distance is only used if far_points_set_nodata is 1, and can must be a distance>=0.0 to (if 0.0 will use an automatic distance value or a distance>0.0)
GIS::SubsampleRaster { raster increment show_advance_bar }
It returns a new raster subsampling the input raster jumping columns and row by increment
show_advance_bar must be 1 to show and advancing bar during the process
