SYNOPSIS

r.in.arc help

r.in.arc input=string output=string [type=string] [title="phrase"] [mult=float]

Parameters:

"input=string
ARC/INFO ascii raster file (GRID) to be imported
"output=string
Name for resultant raster map
"type=string
Storage type for resultant raster map Options: CELL,FCELL,DCELL Default: FCELL
title= 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:

nrows:

xllcorner:

yllcorner:

cellsize:

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

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.
