NAME

       ossim-preproc - ossim-preproc

SYNOPSIS

       ossim-preproc [options] <file-or-directory-to-walk>

OPTIONS

--ch or --create-histogram
Computes full histogram alongside overview.

--chf or --create-histogram-fast
Computes a histogram in fast mode which samples partial tiles.

--compression-quality
Compression quality for TIFF JPEG takes values from 0 to 100, where 100 is best. For J2K plugin,
numerically_lossless, visually_lossless, lossy

--compression-type
Compression type can be: deflate, jpeg, lzw, none or packbits

--compute-min-max
Turns on min, max scanning when reading tiles and writes a dot omd file. This option assumes the
null is known.

--compute-min-max-null
Turns on min, max, null scanning when reading tiles and write a dot omd file. This option tries to
find a null value which is useful for float data.

--create-histogram-r0
Forces create-histogram code to compute a histogram using r0 instead of the starting resolution
for the overview builder. Can require a separate pass of R0 layer if the base image has built in
overviews.

--disable-elev
Will disable the elevation

--disable-notify
Takes an argument. Arguments are ALL, WARN, NOTICE, INFO, FATAL, DEBUG. If you want multiple
disables then just do multiple --disable-notify on the command line. All argument are case
insensitive. Default is all are enabled.

--disable-plugin
Will disable the plugin loader

--dump-filtered-image-list
Outputs list of filtered images and extensions.

--list-entries
Lists the entries within the image

--max Overrides max value for compute-min-max option.

--min Overrides min value for compute-min-max option.

--null <null_value> Overrides null value for compute-min-max option. e.g. -9999.0 for float data

--of or --output-files
Output image files we can open, excluding overviews.

--options
<options.kwl> This can be all or part of the application options. Also used for custom prep, per
file and post system commands. To get a template you can turn on trace to the ossimImageUtil class
by adding "-T ossimImageUtil" to your command.

--ossim-logfile
takes a logfile as an argument. All output messages are redirected to the specified log file. By
default there is no log file and all messages are enabled.

--ot <overview_type> Overview type. see list at bottom for valid types. (default=ossim_tiff_box)

--override-filtered-images
Allows processing of file that is in the filtered image list.

--reader-prop
Adds a property to send to the reader. format is name=value

--rebuild-histogram
Rebuild histogram even if they are already present.

--threads
<threads> The number of threads to use. (default=1) Note a default can be set in your ossim
preferences file by setting the key "ossim_threads".

--tile-size
<size> Defines the tile size for overview builder. Tiff option only. Must be a multiple of 16.
Size will be used in both x and y directions. Note a default can be set in your ossim preferences
file by setting the key "tile_size".

--writer-prop
Adds a property to send to the writer. format is name=value

-K specify individual keywords to add to the preferences keyword list: name=value

-P specify a preference file to load

-T specify the classes to trace, ex: ossimInit|ossimImage.* will trace ossimInit and all ossimImage
classes

-a or --include-fullres
Copy full res dataset to overview file as well as building reduced res sets. Option only valid
with tiff overview builder. Requires -o option.

-d <output_directory> Write overview to output directory specified.

-h Display this information

-i or --internal-overviews
Builds internal overviews. Requires -o option. Option only valid with tiff input image and tiff
overview builder. WARNING: Modifies source image and cannot be undone!

-o Creates overviews. (default=ossim_tiff_box)

-r or --rebuild-overviews
Rebuild overviews even if they are already present.

-s Stop dimension for overviews. This controls how many layers will be built. If set to 64 then the
builder will stop when height and width for current level are less than or equal to 64. Note a
default can be set in the ossim preferences file by setting the keyword "overview_stop_dimension".

Valid overview types: ossim_tiff_box ossim_tiff_nearest

Example commands:

// A single image standard tiff overviews, histogram: ossim-preproc -o --ch <file>

// A single image with j2k overviews(requires kakadu plugin), histogram: ossim-preproc --ot
ossim_kakadu_nitf_j2k --ch <file>

// j2k, histogram, 4 threads

// standard tiff overviews, full histogram, 4 threads: ossim-preproc -r -o --ch --threads 4
<directory_to_walk>

// j2k, histogram (fast mode), 4 threads ossim-preproc -r --ot ossim_kakadu_nitf_j2k --chf --threads 4
<directory_to_walk>

// tiff, jpeg compression, histogram, 4 threads ossim-preproc -r --ch --compression-quality 75
--compression-type jpeg --threads 4 <directory_to_walk> ossim-preproc -r --ch --compression-quality 75
--compression-type jpeg --threads 4 <directory_to_walk>

// Process all the tiffs in a directory feeding "prep", "file", "post" system commands via the --options
option which includes indexing file into the omar database via omar-data-mgr app: ossim-preproc --options
preproc-options.kwl -r -o --ch *.tif

// Contents of preproc-options.kwl used in above command: prep.command0: echo start_time: %{date}
prep.command0.strf_time_format: %Y%m%d%H%M%S prep.command1: mkdir -p %{date} file.command0: mv
%{file_no_ext}.* %{date}/. file.command1: omar-data-mgr -u http://localhost:8080/omar add
%{date}/%{basename} post.command0: echo end_time: %{date} post.command0.strf_time_format: %Y%m%d%H%M%S

NOTES:

--ch equals --create-histogram

--chf equals --create-histogram-fast

Expanded command option variables:

%{basename} = filename without path %{basename_no_ext} = filename without path and without
extension %{date} = Expanded to current zulu time. Default format=yyyymmdd

output format controlled by command0.strf_time_format key.

%{dirname} = path of filename %{file} = filename being processed %{file_no_ext} =
filename with no extension
