ossim-slope(1) ossim-slope


ossim-slope [,options/] ,<output-image>/


--center <lat> <lon>
The center position of the output product. Required if no input DEM is specified.
--dem <filename>
Specifies the input DEM filename. If none provided, the elevation database is referenced as specified in prefs file for the center and ROI specified.
Will disable the elevation
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.
Will disable the plugin loader
--lut <filename>
Specifies the optional lookup table filename for mapping the single-band output image to an RGB. The LUT provided must be in the ossimIndexToRgbLutFilter format and should accommodate the output pixel range. This option forces remap to 8-bit, 0-255 where 255 = 90 deg slope
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.
The range of slope angle (0.0 to 90.0) is remapped to 0-255 (one byte/pixel)
Causes applications API to be output as JSON to stdout. Accepts optional filename to store JSON output.
--roi <meters>
radius of interest surrounding the center point. If absent, the product defaults to 1024 x 1024 pixels, with a radius of 512 * GSD. Alternatively, if a DEM file is specified, the product ROI defaults to the full DEM coverage.
specify individual keywords to add to the preferences keyword list: name=value
specify a preference file to load
specify the classes to trace, ex: ossimInit|ossimImage.*

will trace ossimInit and all ossimImage classes-

Utility for computing the slope at each elevation post and generating a corresponding slope image. The output scalar type is a normalized float with 1.0 = 90 degree angle from the local vertical. Optional 8-bit scalar type is available.Examples:

ossim-slope [options] --dem <input-dem> <output-slope-image-file> ossim-slope [options] --center <lat> <lon> --roi <meters> <output-slope-image-file>
