#1653 closed defect (fixed)

Trunkated cellsize when exporting rasters to arc ascii grid (r.out.arc)

Reported by: reymondin Owned by: grass-dev@…
Priority: major Milestone: 6.4.3
Component: Raster Version: svn-trunk
Keywords: arc ascii grid r.out.arc Cc:
CPU: Unspecified Platform: Unspecified


When exporting rasters to arc ascii grid (r.out.arc) , the cellsize and the corners coordinates in the header are truncated after only 6 decimals. This should not happen as it moves the region.

This could be because when the header is written the following line is used to print the cell size (from source, line 159)

fprintf(fp, "cellsize %f\n", cellsize);

On some systems the %f flag will set the number of decimals to 6.

Fixed in trunk r51615. The module uses now the same method like g.region -g, i.e. full precision for latlon.
