DESCRIPTION
r.in.arc allows a user to create a (binary) GRASS raster map layer
from an ESRI ARC/INFO ascii GRID file with (optional) title.
The ARC/INFO ascii GRID file header has 6 lines (last line optional):
ncols:
nrows:
xllcorner:
yllcorner:
cellsize:
nodata_value:
or alternatively (not supported by r.in.arc, but by
r.in.gdal, last line optional):
ncols:
nrows:
xllcenter:
yllcenter:
cellsize:
nodata_value:
NOTES
r.in.arc handles floating point cell values. The mult
option allows the number of significant figures of a floating point cell
to be increased before importing. Multiples of ten are the most functional
multipliers.
EXAMPLE
To import a ARC/INFO ascii grid, applying a 10x multiplier during import, with title:
r.in.arc input=elev_meters.asc output=elev_decimeters title="Elevation data converted to decimeters" mult=10
