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

Overview Parameters

Description

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

History

Kris Becker2006-03-26 Original version
Kris Becker2008-06-27 Removed references to CubeInfo due to refactor
Kris Becker2009-08-13 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 Becker2009-09-18 Added TargetName to output map file.
Mackenzie Boyd2010-07-19 Modified program to have output go to print.prt file in addition to other outputs.
Kris Becker2010-11-02 Added more detail to error reporting so the offending file can be more readily identified.
Kris Becker, Lynn Weller2012-01-22 Updated the documentation
Debbie A. Cook2012-07-06 Updated Spice members to be more compliant with Isis coding standards. References #972.
Debbie A. Cook2012-10-11 Updated to use new Target class. References Mantis tickets #775 and #1114.
Tyler Wilson2016-08-25 Updated to use upated Camera/CameraPointInfo classes which include improved approximations to Pixel/Detector/Line/Sample resolutions, as well as providing the ability for developers to order the fields in CSV/Pvl output. References #476"

Mapping: PRECISION

Description

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).
