## 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

## SEE ALSO

r.in.gdal r.out.arc

## AUTHOR

Unknown German author, updated by Bill Brown to floating point support.
