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 ele
ment 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 projec
tion. "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.
