mosrange

mosrange computes and outputs the latitude and longitude ranges of a set of Level1 images (i.e. non-projected), 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 ways. 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 number of digits of precision for many of the Mapping group parameters used to project images.

ONERROR, ERRORLOG, and ERRORLIST parameters offer better error handling and diagnostics when problems are encountered processing the input file list. ONERROR dictates whether mosrange will abort or continue when an error occurs. If ONERROR=FAIL (default behavior), mosrange aborts upon error without generating a map file. If ONERROR=CONTINUE, mosrange produces an output map file with data collected from all successfully processed images. A detailed list of files that fail and their associated errors are written to the ERRORLOG file if provided. A simple list of failed files is written to the ERRORLIST file if provided.

The primary use of mosrange 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

Description

Use this parameter to select the filename of a cube with camera labels.

Description

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.

Description

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.

Description

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

Description

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.

Description

The latitude type for the projection. It can either be Planetocentric or Planetographic. PLANETOCENTRIC is the default.

Description

The longitude direction for the projection. It can have a direction of Positive East or Positive West. POSITIVEEAST is the default.

Description

The longitude domain for the projection. It can either have a domain of 180 or 360. 360 is the default.

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).

Description

This flag is provided to specify what action is to be taken should an error occur processing the input file list. A detailed list of errors for each file will be recorded to ERRORLOG if a file name is provided. A list containing the file names that failed will be written to ERRORLIST if provided. If ONERROR=FAIL, a single error will result in an abort. FAIL is the default (to preserve existing behavior).

Description

Each file that encounters an error will produce the issue that cased the error. The ERRORLOG file can be specified to get a detailed account of why each file failed to successfully complete. Data collected from this process will be written to the specified ERRORLOG in the form of a PVL object.

Description

The filename of each cube that encountered an error will be written to this file if provided. The ERRORLIST file can be used to difference against the input list to determine all the successful files included in the mapping statistics.
