NAME
i.landsat.trim - Trims the "fringe" from the borders of Landsat images, for each band separately or with the MASK where coverage exists for all bands. Optionally saves vector footprints of trimmed rasters and MASK. Works with Landsat 5, Landsat 7 (SLC-on).
KEYWORDS
imagery, landsat, raster, vector
SYNOPSIS
i.landsat.trim
i.landsat.trim help
i.landsat.trim [-mgaf] [input=string] [input_base=string] [input_prefix=string] output_prefix=string [rast_buffer=integer] [gener_thresh=integer] [--verbose] [--quiet]
Flags:
- -m
- Trim raster(s) with the MASK where coverage exists for all bands
- -g
- Trim raster(s) with the generalized footprint from all bands
- -a
- Process all bands
- -f
- Save vector footprint(s) of trimmed raster bands or coverage MASK
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
