ossim-slope - 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.
- --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
- --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
- --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.
- --remap
- The range of slope angle (0.0 to 90.0) is remapped to 0-255 (one
byte/pixel)
- --request-api
- 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.
- -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-
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>
