lev1pt - Generate geometric information for a point in a cube This program generates geometric information for a single sample/line or lat/lon position in a cube or list of cube files. The information listed includes the following geometric parameters: Sample Line Latitude Longitude Sample Resolution (KM) Line Resolution (KM) Aspect Ratio Phase Angle Incidence Angle Emission Angle North Azimuth Angle The North Azimuth Angle is the clock-wise angle from an imaginary three o'clock axis with the origin at the center of the pixel. The program can operate on a single cube using the FROM parameter, in which case the information is output to the log file (i.e., print.prt) and the terminal screen. Or, a FROMLIST can be specified, in which case a list of cubes is expected to be in the file and the information will be output in ascii to the file specified by the TO parameter. The format for TO file is one line for each cube which ran successfully, where each line contains the following values separated by spaces: sample line latitude longitude sample resolution line resolution aspect ratio phase angle incidence angle emission angle north azimuth filename In addition, a TOERR file can be generated which will contain a list of cubes that failed. Programmer: Debbie A. Cook, U.S.G.S., Flagstaff, AZ
Parm | Description | Default |
---|---|---|
FROM | Input cube file name (default extension is .cub) OR | -- |
FROMLIST | File containing a list of cubes | -- |
TO | ASCII file to write information | -- |
TOERR | List of unsuccessful cubes | -- |
SAMP | Sample position in cube(s) | -- |
LINE | Line position in cube(s) OR | -- |
LAT | Latitude of position in cube(s) | -- |
LON | Longitude of position in cube(s) |
ADDITIONAL NOTES:
Parm | Description |
---|---|
FROM | Input cube file name. If the file extension is omitted, then ".cub" will be assumed. You can't use FROMLIST if you use this parameter. |
FROMLIST | A file containing a list of cubes which will all be processed. You can't use FROM if you use this parameter and you must specify TO. |
TO | A file which will contain the output information for the cube(s). This parameter must be specified when a FROMLIST is entered. Type help * to find out about the format of the TO file. |
TOERR | A file which will contain the cubes in FROMLIST which failed. |
SAMP | The sample position in the file(s) to describe. If SAMP, LINE, LAT, and LON are defaulted, the center of the image will be described. |
LINE | The line position in the file(s) to describe. See SAMP for the default. |
LAT | The latitude position to describe. See SAMP for the default. |
LON | The longitude position to describe. See LINE for the default. |
