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

       Unknown German author, updated by Bill Brown to floating point support.
