ISIS 3 Application Documentation
Compute the lat/lon range of a set camera images for mosaicking
Description
This program computes and outputs the
latitude/longitude
range of a set of images in camera space, as well as the
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>
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

Original version
|
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.
|
Kris Becker, Lynn Weller | 2012-01-22 |
Updated the documentation
|
Debbie A. Cook | 2012-07-06 |
Updated Spice members to be more compliant with Isis coding standards. References #972.
|
Debbie A. Cook | 2012-10-11 |
Updated to use new Target class. References Mantis tickets #775 and #1114.

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).
