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

Overview Parameters

Description

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

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).

Errorhandling: ONERROR

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).

Type string
Default FAIL
Option List:
Option Brief Description
CONTINUE Continue processing all the input file list if an error occurs Continue to produce an output map file with data collected from any number of successfully processed images when one or more errors are encountered with the input processing list. This option will cause the application to continue processing all files and generate a mapping file if at least one is successful.
FAIL Terminate the application when an error occurs If any file produces an error when determining mapping statistics, ONERROR=FAIL will cause the application to abort with an error without generating a map file. The filename and detailed error are written to ERRORLOG if provided. The filename alone is written to ERRORLIST if provided.

Errorhandling: ERRORLOG

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.
