planorth - Create TFILE for Planetary cubes in Orthographic
Create the transformation data file (TFILE) for GEOM (see GEOM for more
information) to project Clementine, Galileo, Mariner, Viking and Voyager
LEVEL 1 cubes to an Orthographic projection and correct camera
distortions.  This program does not do the actual transformation of the
cube, GEOM must be run using the TFILE created by this program.  The map
resolution is calculated by the program to retain the full resolution of
the LEVEL 1 cube.

PROGRAMMER: Kay Edwards, USGS, Flagstaff, Az

Input cube name
(default extension is .cub)

NONE

Transformation file

Center longitude of orthographic
(default is subspacecraft lon)

--

Image resolution (km/pix)
      or

--

Image resolution (pix/deg)

--

Latitude range
(default=cube range)

--

Longitude range
(default=cube range)

ADDITIONAL NOTES:

Parm	Description
FROM	Input cube file name. If the file extension is omitted, then ".cub" will be assumed.
TFILE	This is the name given to a data file needed by GEOM. After this program has finished, GEOM must be run to actually transform the cube.
CLAT	This is the center latitude of the Orthographic projection. If CLAT is left at the default, the program will set the center latitude of the Orthographic to the subspacecraft latitude. If you are going to mosaic several cubes while in the Orthographic projection, you must pick a common center latitude for all the cubes in the mosaic.
CLON	This is the center longitude of the Orthographic projection. If CLON is left at the default, the program will set the center longitude of the Orthographic to the subspacecraft longitude. If you are going to mosaic several cubes while in the Orthographic projection, you must pick a common center longitude for all the cubes in the mosaic.
KM	Specifies the map resolution in kilometers/pixel. The default will find the map resolution at the subspacecraft point (the closest point on the planet).
DEG	Specifies the map resolution in pixels/degree. The default will be to use KM to define the resolution. If any value is entered for DEG, then the value in KM will be ignored.
LAT	The default procedure is to automatically find the latitude and longitude range on the cube. If you want to enter your own latitude range, the longitude range must be entered also, because if this option is used no range is found on the cube.
LON	See LAT.
