.SH DESCRIPTION
\fIr.in.arc\fR allows a user to create a (binary) GRASS raster map layer
from an ESRI ARC/INFO ascii GRID file with (optional) title.
.PP
The ARC/INFO ascii GRID file header has 6 lines (last line optional):
\fC
.DS
.br
     ncols:
.br
     nrows:
.br
     xllcorner:
.br
     yllcorner:
.br
     cellsize:
.br
     nodata_value:
.br
.DE
\fR
or alternatively (not supported by \fIr.in.arc\fR, but by
\fIr.in.gdal\fR, last line optional):
\fC
.DS
.br
     ncols:
.br
     nrows:
.br
     xllcenter:
.br
     yllcenter:
.br
     cellsize:
.br
     nodata_value:
.br

\fR
.SH NOTES
\fIr.in.arc\fR handles floating point cell values. The \fBmult\fR
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.
.SH EXAMPLE
To import a ARC/INFO ascii grid, applying a 10x multiplier during import, with title:
\fC
.DS
.br
r.in.arc input=elev_meters.asc output=elev_decimeters title="Elevation data converted to decimeters" mult=10
