tiff2geotiff#
usage: tiff2geotiff [options] input... output
where options are:
-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
-m file Specify filename with multiple timestamps and image placement info:
Each line of file has date/timestamp, and 8 floats;
first four are lon/lat corners of plot area,
second four are relative positions of plot corners in page.
This option requires option -4
-M file Specify filename with multiple timestamps, w/o georeferencing:
Each line of file has date/timestamp only
Option -4 must not be specified.
-n llx lly urx ury
Install longitude/latitude extents;
Four lon and lat values must in quotes in the order:
lower-left longitude, lower-left latitude,
upper-right longitute, upper-right latitude
This option requires option -4
Option '-m' overrides this option
-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
