ISIS Documentation

mat2cnet

Converts an ISIS2 match point file to an ISIS control network file.

This program converts an ISIS2 match point file to an ISIS control network file. It requires a list file of ISIS2 cubes and corresponding list file of ISIS cubes. Note: In order to identify which ISIS cube corresponds to a particular ISIS2 cube, these lists must be the same length and ordering. That is, if the first cube of the ISIS2 list was imported from a particular raw image (observation), then the first cube of the ISIS list must be imported from the same image (observation), and so on for each cube listed.

This application also requires a match point file, an output Control Network pvl name, a network ID, a target and a description. The user may also choose whether to input a RAND PPP file containing latitude, longitude and radius for each corresponding point ID and to create an output RAND PPP log. This program converts the radius values in these files from km to meters before adding them to the output control network. If a RAND PPP file is not entered, all the points in the MATCH file will be set to type Free. If a RAND PPP is input, then any points not found in this file will still be set to Free and the user may choose whether to set points found in both the RAND and MATCH files to Fixed or Free. Any points found in the RAND file without measurements in the MATCH file will not be included in the output control net. The corresponding lines from the RAND PPP file for these points will be copied to the RAND PPP log.

The following indicates how the ISIS2 Class is translated to an ISIS MeasureType

  • "T" (Truth) is translated to Reference
  • "S" (SubPixel) is tranlated to RegisteredSubPixel
  • "M" (Measured) is translated to RegisteredPixel
  • "A" (Approximate) is tranlated to Candidate
  • "U" (Unmeasured) is translated to Candidate and the measure is set to Ignore

Parameters

ISIS2 Files

A text file containing one column of ISIS2 cube file names. Every file used in the match point file should be represented in this list. Note: The cubes must be available for the program to open and must be in the same order as the ISIS cubes in LIST3. An error will be thrown if the number of files in this list does not match the number of files in LIST2, or if the IMAGE_ID and IMAGE_NUMBER keywords are not found in any ISIS2 cube.
Type filename
File Mode input
Filter *.lis *.txt *.lst

Use this parameter to specify the ISIS2 match point file to be converted to an ISIS control network file. This file must contain a two line header. The first line of the header must have the "Matchpoint Total" keyword and a value for the number of measures in the match point file. The second line of the header should be text labels for each column. The match point file has 7 columns: PointID, FSC, LINE, SAMP, CLASS, DIAMETER, and Comments. The Point ID is made up of alphanumeric characters, FSC is an integer, LINE and SAMP must be doubles. CLASS is used to determine the measure type. Valid values include T (set to reference measure, validated manual), M (validated manual), S (validated automatic), or U (if line/samp=0/0, set unmeasured, otherwise set estimated). The DIAMETER column is used in the case of a crater. Comments are not read in to this application. A match point file may only have one line for a particular PointID/FSC combination, otherwise an error will be thrown since there is no way to determine which line contains correct values.
Type filename
File Mode input
Filter *.mat *.dat *.txt *.tbl

This parameter indicates whether a RAND PPP (Pole, Point, Picture) file will be input. Valid RAND PPP files for mat2cnet are detailed in the PPP parameter description.
Type boolean
Default FALSE
Inclusions
  • PPP
  • POINTTYPE
  • POINTLOCK
  • LOG

Use this parameter to specify the RAND PPP file to assign lat/lon/rad values associated with corresponding point IDs from the MATCH file. These files do not contain headers and have 4 unlabeled columns: LATITUDE, LONGITUDE, RADIUS, and PointID. The lines of original RAND PPP files have exactly 79 characters, and columns are right justified with specific lengths, namely, 24, 24, 24, and 7. The only edited RAND PPP files that are valid for this program are those that have a single space added between the RADIUS and the PointID. LATITUDE, LONGITUDE, and RADIUS values must be doubles and PointID is alphanumeric. If this file contains a Point ID that does not exist in the match point file, it will not be added to the ControlNet output and the corresponding lines from the RAND PPP file will be copied to the LOG output file.
Type filename
File Mode input
Filter *.ppp *.dat

This parameter determines the ControlPoint type to which points will be set if they are found in the RAND PPP file and have corresponding measurements in the MATCH file. This parameter defaults to Fixed. Note: All points from the MATCH file not found in the RAND PPP file will be set to Free and all points from the RAND PPP file not found in the MATCH file will be omitted from the output Control Network.
Type string
Default FIXED
Option List:
Option Brief Description
FIXED Set PointType keyword to Fixed for points in RAND PPP file If this option is selected, any points in the RAND PPP file that has measurements in the MATCH file will have its PointType keyword set to Fixed in the output ControlNet.
FREE Set PointType keyword to Free for points in RAND PPP file If this option is selected, any points in the RAND PPP file that has measurements in the MATCH file will have its PointType keyword set to Free in the output ControlNet.

This parameter indicates whether control points found in the RAND PPP file will be locked. That is, if this parameter is set to true, then each ControPoint in the output ControlNet that exists in the RAND PPP file will have the keyword EditLock set to true. This prevents any editing by most ISIS programs (with the exception of jigsaw) to the latitude, longitude, and radius values associated to the points in the RAND PPP file. Furthermore, the reference measures of each of these points will be treated as if they are locked, preventing any editing by ISIS programs to the sample and line values found in the match point file. This parameter defaults to TRUE and can only be used if the INPUTPPP parameter is set to true.
Type boolean
Default TRUE

This file will contain the Point IDs of all control points that were found in the RAND PPP file but had no measurements in the MATCH file. Note: This log is not a typical results log that contains the GUI log output.
Type filename
File Mode output
Internal Default No Log Output
Filter *.log *.txt

ISIS3 Files

A text file containing one column of ISIS cube file names. Every file used in the match point file should be represented in this list. Note: The cubes must be available for the program to open and must be in the same order as the ISIS2 cubes in LIST2. An error will be thrown if the number of files in this list does not match the number of files in LIST2.
Type filename
File Mode input
Filter *.lis *.txt *.lst

Use this parameter to specify the file name of the output ISIS3 control network.
Type filename
File Mode output
Filter *.net *.pvl *.ctl *.cnet

Control Network Keyword Settings

The Description keyword of the output ControlNet will be set to this string value. This should be a brief description of the control network file to be created.
Type string

The NetworkId keyword of the output ControlNet will be set to this string value. The NetworkId is a single word identifier assigned to this particular ControlNet file. This string should be unique to this output file.
Type string

The TargetName keyword of the output ControlNet will be set to this string value. This is the planetary body targeted in the images in the input file lists. The TargetName value should appear in all cubes used in the output ControlNet.
Type string

This parameter indicates whether control measures found in the match point file will be locked. That is, if this parameter is set to true, then each ControlMeasure in the output ControlNet file will have the keyword EditLock set to true. This prevents any editing by ISIS3 programs to the sample and line values associated to each measure found in the match point file. This parameter defaults to FALSE.
Type boolean
Default FALSE
