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