NAME

r.in.arc - Converts an ESRI ARC/INFO ascii raster file (GRID) into a (binary) raster map layer.

KEYWORDS

SYNOPSIS

r.in.arc
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.
