Compute the lat/lon range of a set camera images for mosaicking

History
This program computes and outputs the latitude/longitude range of a set of images in camera space, as well as the pixel resolution and the oblique pixel resolution.. It creates a cam2map ready map file with the extents of the latitude/longitude ranges of the image set.
The user can select the type of map projection preferred by two different means. The PROJECTION parameter allows direct specification of an ISIS supported projection. Or, the user can select a map file from the ISIS map template system that contains the projection name. If none of these options are used, then Equirectangular is the default.
mosrange provides better control over the values of the latitude/longitude ranges by providing a PRECISION parameter. This parameter specifies the maximum nuber of digits precision for many of the Mapping group parameters used to project images.
Its primary use is to provide a quick, simple and batchable means of creating map files for projections.
An example of the output generated is:
Group = Mapping ProjectionName = Equirectangular TargetName = Mercury EquatorialRadius = 2440000.0 <meters> PolarRadius = 2440000.0 <meters> LatitudeType = Planetocentric LongitudeDirection = PositiveEast LongitudeDomain = 360 PixelResolution = 505.3668 <meters/pixel> ObliquePixelResolution = 791.251 <meters/pixel> Scale = 84.2676 <pixels/degree> MinPixelResolution = 483.45317995544 <meters> MaxPixelResolution = 527.28051834369 <meters> CenterLongitude = 165.9728 CenterLatitude = -13.6612 MinimumLatitude = -21.5164 MaximumLatitude = -5.806 MinimumLongitude = 133.7863 MaximumLongitude = 198.1593 # Actual Parameters without precision applied PreciseCenterLongitude = 165.97281458717 PreciseCenterLatitude = -13.661167089917 PreciseMinimumLatitude = -21.516314016725 PreciseMaximumLatitude = -5.806020163109 PreciseMinimumLongitude = 133.78639979231 PreciseMaximumLongitude = 198.15922938202 End_Group End

If this file is given, only the ProjectionName keyword is used to determine the type of projection desired. If you know the type already as well as the proper spelling required by ISIS, then you may use PROJECTION as an alternative to this file.

This file will contain a map projection file suitable for projecting the given set of images. This file will contain all the parameters suitable for using directly in cam2map.

Each input file will have its geometry computed and the results can be written to this file.

Use this named projection as the type of projection you wish to create. It should be the complete valid name as required by the cam2map application. This name can also be provided in the MAP parameter if you do not know the proper spelling/format required for ISIS projections.

This parameter provides some control over how the Latitude and Longitude min/max values are written to the map file. Note that this is useful for creating easy values to use in subsequent applications that may require these values. If these values are not specified, about 12 digits of precision will be used.
Note that you can use a negative number which has the effect of rounding the whole integral number. A value of 0 will produce an integral whole number, effectively removing the decimal portion of the numbers. A positive number will truncate up (maximums using the ceil function) or down (minimums using the floor function) range values such as MinimumLatitude and MaximumLatitude. The pixel resolution is rounded using same technique (with the rint fuction).

Kris Becker | 2008-06-27 | Removed references to CubeInfo due to refactor |
Kris Becker | 2009-08-13 | Added parameters LATTYPE, LONDIR and LONDOM; Now computes pixel Scale in pixels/degree; added additional parameters to the output map file so it is more compliant with projection requirements based upon input parameters and established mapping group keywords. |
Kris Becker | 2009-09-18 | Added TargetName to output map file. |
Mackenzie Boyd | 2010-07-19 | Modified program to have output go to print.prt file in addition to other outputs. |
Kris Becker | 2010-11-02 | Added more detail to error reporting so the offending file can be more readily identified. |
