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
