I tried Glynn's method mentioned in that thread, specifically: r.mapcalc MASK = '!isnull(MAP)' which worked. Checking the range of the raster I used for a mask in my r.mask command, it was 0-32767; so shouldn't r.mask in=MAP also create a mask where any non-null cell in the input raster exists? Here's the output from r.info for the mask I created using r.mask: $ r.info MASK +----------------------------------------------------------------------------+ | Layer: MASK Date: Tue Feb 5 11:53:33 2008 | | Mapset: PERMANENT Login of Creator: epatton | | Location: Charlottetown | | DataBase: /home/epatton/Projects | | Title: Reclass of EC_Charlottetown_Bathy_March_2007_1m_fill_shade_comb | | Timestamp: none | |----------------------------------------------------------------------------| | | | Type of Map: reclass Number of Categories: 1 | | Data Type: CELL | | Rows: 999 | | Columns: 1220 | | Total Cells: 1218780 | | Projection: UTM (zone 20) | | N: 5119638 S: 5118639 Res: 1 | | E: 491266 W: 490046 Res: 1 | | Range of data: min = 1 max = 1 | | | | Data Source: | | Reclassified map based on: | | Map [EC_Charlottetown_Bathy_March_2007_1m_fill_shade_comb] in mapset | | | | Data Description: | | NT] | | | | Comments: | | T] | | | |----------------------------------------------------------------------------| | Reclassification of [EC_Charlottetown_Bathy_March_2007_1m_fill_shade_com | | | | Category Original categories | | | | 1 0-32737 | +----------------------------------------------------------------------------+ ~ Eric. _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
