I thought r.external was a read-only link.

[GRASS-dev] r.null apparently doesn't work on vrt via r.external on G7
Hi All, Is it an expected behaviour that r.null doesn't affect vrt raster linked via r.external? Tested on forest map 2000 available for download from http://forest.jrc.ec.europa.eu/download/data/forest-data-download/ I build the mosaic with gdalbuildvrt and then use r.external then I want to set to null the values 0,2,3: r.null mosaic setnull=0-2-3 this command doesn't have any effect on the map. thanks madi -- Best regards, Dr. Margherita DI LEO Scientific / technical project officer European Commission - DG JRC Institute for Environment and Sustainability (IES) Via Fermi, 2749 I-21027 Ispra (VA) - Italy - TP 261 Tel. +39 0332 78 3600 margherita.di-...@jrc.ec.europa.eu Disclaimer: The views expressed are purely those of the writer and may not in any circumstance be regarded as stating an official position of the European Commission. ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
