r.in.arc help
r.in.arc input=string output=name [type=string] [title="phrase"] [mult=float] [--overwrite] [--verbose] [--quiet]

Flags:

--overwrite

Allow output files to overwrite existing files

--verbose

Verbose module output

--quiet

Quiet module output

Parameters:

input=string

ARC/INFO ASCII raster file (GRID) to be imported

output=name

Name for output raster map

type=string

Storage type for resultant raster map
Options: CELL,FCELL,DCELL
Default: FCELL

title=phrase

Title for resultant raster map

mult=float

Multiplier for ASCII data
Default: 1.0

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:

     ncols:

     nrows:

     xllcorner:

     yllcorner:

     cellsize:
or alternatively (not supported by r.in.arc, but by r.in.gdal):

     ncols:

     nrows:

     xllcenter:

     yllcenter:

     cellsize:

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.
