NAME
r.out.elas - Export a GRASS raster map layer to an ELAS
raster file
(GRASS Raster Data Export Program)
SYNOPSIS
r.out.elas
r.out.elas help
r.out.elas [-h]
input=name
output=name
DESCRIPTION
r.out.elas" exports a GRASS cell file to an ELAS raster file.
OPTIONS
Flags:
- -f
- Floating-point ELAS output file will be created.
Parameters:
- input=name
- GRASS input cell file name.
- output=name
- ELAS output raster file name.
"r.out.elas" will transfer and convert a GRASS cell file to an ELAS
raster file. The GRASS cell file will be a 1 to 4 byte integer per
element file. This GRASS cell file may be converted to either a 1 to 4
byte integer per element ELAS file (default) or a 4 byte
floating-point per element ELAS file. Color values will be transferred
from GRASS to ELAS for GRASS 1 byte integer per element files only.
"r.out.elas" only transfers GRASS cell files that have either an
unreferenced XY or UTM projection. Whether the GRASS cell file is
either an unreferenced XY or UTM projection, the ELAS file created
will be a UTM projection. "r.out.elas" will transfer the GRASS cell
file based on the selected region and will only transfer the portion
of the GRASS cell file that is within that selected region.
"r.out.elas" will notify the user as to whether the current region has
the same values as the "cellhd" file for the GRASS cell file being
transferred to ELAS. Since the area transferred to ELAS is determined
by the region (WIND file) and not the cellhd file then the
notification of a difference between these files will indicate that
not all of the GRASS cell file will be transferred to ELAS. Also, this
program will notify the user as to whether the raster "MASK" is on or
not.
