Hi
It's on grass57_exp_2004_11_13 but the problem was in all older Grass
versions I used.
Problem: 'r.in.gdal' and 'r.in.arc type=FCELL' output a different raster
than 'r.in.arc type=DCELL'. And the latter outputs a proper one.
I've got a following ArcInfo ASCIIGrid:
ncols 6101
nrows 3201
xllcorner 649.5
yllcorner 849.5
cellsize 1
NODATA_value -9999
280.2687 280.2776 280.2866 (...)
The value range should be:
min=176.945400
max=284.015600
And it is the case when 'r.in.arc type=DCELL' is used for importing.
However, if 'r.in.gdal' or 'r.in.arc type=FCELL' is used then:
min=176.945404
max=284.015594
I suppose there should be no difference. What is the reason?
BTW - I couldn't find a GUI entry for the 'r.in.arc' in the
File->Import->Raster. Shouldn't it be there?
