GEOTIFCP

NAME

geotifcp - Copy TIFF with updated GeoTIFF Metadata

SYNOPSIS

geotifcp [options] [-e esri_worldfile] [-g metadata] input output

DESCRIPTION

geotifcp is identical in function to the LIBTIFF program tiffcp, with the additional feature that if the "-g" option is used the GeoTIFF information from the file will be installed into the output file. The "-e worldfile" option will override the tiepoint and scale information from the metadata file based on the contents of the ESRI worldfile.

If the "-g" option is not used the geotiff information from the source file is preserved in the new output file.

"geotifcp" inherits all the other file-transformation capabilities of the tiffcp program; for help on the additional parameters give the command:

% geotifcp -h

The metadata format is the same as is described in the listgeo(1) program. Normally metadata files for use with geotifcp are generated from a similar file with listgeo, and then modified by hand as required.

OPTIONS

-g file

install GeoTIFF metadata from file

-4 proj4_str

install GeoTIFF metadata from proj4 string

-e file

install positioning info from ESRI Worldfile file

	-a		append to output instead of overwriting
	-8		write BigTIFF instead of default ClassicTIFF

-o offset

set initial directory offset

-p contig

pack samples contiguously (e.g. RGBRGB...)

-p separate

store samples separately (e.g. RRR...GGG...BBB...)

	-s		write output in strips
	-t		write output in tiles
	-i		ignore read errors
	-d		truncate 8 bitspersample to 4bitspersample
	-r #		make each strip have no more than # rows
	-w #		set output tile width (pixels)
	-l #		set output tile length (pixels)

-f lsb2msb

force lsb-to-msb FillOrder for output

-f msb2lsb

force msb-to-lsb FillOrder for output

-c lzw[:opts]

compress output with Lempel-Ziv & Welch encoding

-c zip[:opts]

compress output with deflate encoding

-c jpeg[:opts]

compress output with JPEG encoding

-c packbits

compress output with packbits encoding

-c g3[:opts]

compress output with CCITT Group 3 encoding

-c g4

compress output with CCITT Group 4 encoding

-c none

use no compression algorithm on output

Group 3 options:

	1d		use default CCITT Group 3 1D-encoding
	2d		use optional CCITT Group 3 2D-encoding
	fill		byte-align EOL codes

For example, -c g3:2d:fill to get G3-2D-encoded data with byte-aligned EOLs

JPEG options:

	#		set compression quality level (0-100, default 75)
	r		output color image as RGB rather than YCbCr

For example, -c jpeg:r:50 to get JPEG-encoded RGB data with 50% comp. quality

LZW and deflate options:

#

set predictor value

For example, -c lzw:2 to get LZW-encoded data with horizontal differencing
