(GRASS Raster Data Import Program)

SYNOPSIS

r.in.arc
r.in.arc help
r.in.arc input=name output=name [title="phrase"] [mult=multiplier]

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.

OPTIONS

Parameters:

input=name
Name of an existing ASCII raster file to be imported.
output=name
Name to be assigned to resultant binary raster map layer.
title="phrase"
Title to be assigned to resultant raster map layer.
mult=multiplier
Multiply all raster cell values by multiplier. multiplier is a floating point value, and has a default value of 1.0.
The input file has a header section which describes the location and size of the data, followed by the data itself.

The header has 6 lines:

ncols:
nrows:
xllcorner:
yllcorner:
cellsize:
or alternatively (not supported in r.in.arc):
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.
