Outputs latitude/longitude at line/sample or reverse

This program requires the user supply a cube in a map projection. The user must also enter one of the following coordinates: 
      line/sample
      latitude/longitude
      x/y
The program will then compute the other two coordinates. For example, entering a line/sample will cause the program to compute a latitude/longitude and x/y. The output can be sent to a text file using the TO parameter and can be read in a script via the "getkey" program. Example output: 
      Group = Results
        Filename                 = /home/mboyd/mapped.cub
        Sample                   = 400.0
        Line                     = 400.0
        PixelValue               = Null
        X                        = 36094.582198722
        Y                        = -2602604.7032335

        # Input map coordinate system
        PlanetocentricLatitude   = -85.828401770565
        PositiveEast180Longitude = 26.807891885122

        # Location in other coordinate systems

History

Jeff Anderson2003-02-05 Original version
Stuart Sides2003-11-07 Modified results pvl to not include the results group
Brendan George2005-11-21 Added application test
Elizabeth Miller2006-06-29 Changed name to mappt and made ui look like skypt and campt
Sean Crosby2007-04-12 Changed flatfile output so it duplicates PVL data. User now required to entered a flatfile name.
Steven Lambright2008-05-13 Removed references to CubeInfo
Steven Koechle2008-08-14 Added pixel value to the output group
Mackenzie Boyd2010-01-12 Modified output to include all coordinate systems for latitude and longitude and clearly declare the input files coordinate system. Improved documentation.
Mackenzie Boyd2010-02-16 Added many parameters accesible when inputing a lat lon, all under coordinate system. These parameters are to select the input coordinate system being used. Updated documentation to match.
Tracie Sucharski2012-12-06 Changed to use TProjection instead of Projection. References #775
Kimberly Oyama2013-11-22 Changed the order in which the keywords are output to the csv, not the pvl, so it no longer depends on the coordinate system of the input cube. Fixes #1614.
Janet Barrett2014-08-04 Added new parameter, ALLOWOUTSIDE, to control the reporting of latitude/longitude and line/sample information that falls outside the boundaries of the image. Also added a message to the output results if the line,sample falls outside the image boundaries, regardless of the setting of the ALLOWOUTSIDE parameter. This will help the user detect results that fall outside the image even if they are allowing for it. Fixes #1929.

Parameters

Files

Input cube which must have a Mapping group in the labels.

A text file which will contain the results of this program. This file can be used in conjunction with the "getkey" program in order to pass the results to another program when developing scripts if the PVL format is selected.

If this option is selected, the output from the application will be appended to the file. If it is not selected, any information in the TO file will be overwritten.
Type boolean
Default TRUE

This parameter is used to select the type of coordinate which will be used to compute the other two remaining coordinates.

This is the sample position used to compute information about the camera state at the pixel.
Type double

This is the line position used to compute information about the camera state at the pixel.
Type double

This is the latitude value used to compute the other coordinate values. The latitude will be interpreted as either Planetographic or Planetocentric latitude depending on the option selected under coordinate system.
Type double

This is the longitude value used to compute the other coordinate values. The longitude will be interpreted as either PositiveEast or PositiveWest longitude and -180 to 180 or 0 to 360 domain depending on the option selected under coordinate system.
Type double

This is the x coordinate value used to compute the other coordinate values. It will be a projection X value in meters.
Type double

This is the y coordinate value used to compute the other coordinate values. It will be a projection Y value in meters.
Type double

Selecting this parameter will enable the 'COORDLIST' parameter in the GUI.

Note that this parameter is optional when running mappt on the command line.

Type boolean
Default FALSE
Exclusions
  • SAMPLE
  • X
  • Y
  • LINE
  • LATITUDE
  • LONGITUDE
Inclusions
  • COORDLIST

An input comma-delimited flatfile of image, ground or projection coordinates. This allows the program to process multiple coordinates in a single run of mappt, and output the results to the specified output file.

Expected order for image coordinates: sample, line
Expected order for ground coordinates: latitude, longitude Expected order for projection coordinates: X, Y

The "Error" keyword will only appear when using a coordinate list. The value of "Error" will then be NULL unless an error occurs during the processing of a coordinate in the coordinate list. Then, the value of this keyword will be the error message. This allows for mappt to continue processing the remaining coordinates in the coordinate list.

For the input of Latitude and Longitude, mappt expects Planetocentric Latitude (within -90 to 90 boundary) and Positive East Longitude (with 0-360 boundary) to find the location in the input camera image.

Type filename
File Mode input
Internal Default None

  • X
  • Y
  • LATITUDE
  • LONGITUDE

The Allowoutside parameter influences how mappt will report resulting latitude/longitude and sample/line coordinates that fall outside the input cube pixel boundaries.

The default is set to True, which allows mappt to return the values that are outside the cube pixel boundaries, For example, a given latitude/longitude might return a sample location of -1.0 (a single whole pixel coordinate off the left side of the image). This is a feature of the ISIS camera models.

When set to False, if a returned coordinate is off the image, mappt will fail. This failure can be indicated and ignored within a batch script when only coordinates that fall within the image cube pixel boundaries are desired.

Type boolean
Default true
