duplicates

(Compiled by DL)

Purpose: Duplicates writes an ordered list of unique landmark names to make_script.in, the .in file required by make_scriptP to generate run scripts for processing landmarks using lithosP. Duplicates checks that the landmarks are included in LMRKLIST.TXT, and that LMKFILES and MAPFILES exist for each entry.

Requires

• LMRKLIST.TXT - Full list of landmarks, appended with 'END'.

• LIST.TXT - Temporary list of the subset of landmarks which the user wishes to process appended with 'END', for sorting and removal of duplicates using the program duplicates.

• LMKFILES/ - Directory containing all the LMKFILES listed in LMRKLIST.TXT.

• MAPFILES/ - Directory containing all the MAPFILES for landmarks listed in LMRKLIST.TXT.

Output

• make_script.in - .in file required by make_scriptP for generating the run scripts required to iterate the landmarks using lithosP.

Using duplicates

Create Input File

Create LIST.TXT, a list of landmark names for the landmarks intended for processing using lithosP, appended with the end-of-file identifier, 'END', see example below.

Run duplicates

duplicates processes landmark names as follows:

• for every landmark listed in LMRKLIST.TXT:

  • duplicates checks that the MAPFILE exists;
  • duplicates obtains the maplet's Q-size and Ground Sample Distance (GSD) from the LMKFILE;
  • duplicates sorts the list by decreasing GSD and increasing name (lat/wlong identifier and numeric identifier);
  • duplicates discards duplicate entries;
• for every landmark listed in LIST.TXT:

  • duplicates checks that the landmark is also listed in LMRKLIST.TXT, if so the landmark is included in the output;

• duplicates writes the sub-set of ordered landmarks to make_script.in.

NB:

• The LANDMARK and MAP files for the landmarks included in LMRKLIST.TXT must exist in LMKFILES/ and MAPFILES/;

• duplicates only considers landmarks contained in LIST.TXT, that are also contained in LMRKLIST.TXT.

Example

Example LMRKLIST.TXT:

EE0001
EE0002
EE0003
EE0004
EE0005
EE0006
EE0007
EE0008
EE0009
EE0010
EF0001
EF0002
EF0003
EF0004
EF0005
EF0006
EF0007
EF0008
EF0009
EF0010
END

Example LIST.TXT:

EF0006
EF0006
EF0006
FF0006
EE0004
FF0009
EE0007
EE0010
EE0009
EE0006
EF0010
EF0004
EE0005
EF0005
EF0008
FF0008
EE0008
FF0005
FF0010
EF0009
EF0007
FF0004
FF0007
END

Note that the example LIST.TXT contains a disordered list of landmark names, and many duplicate entries. Further note that the FF* landmarks are not included in the example LMRKLIST.TXT, and that the example LIST.TXT does not include any landmarks ending in 1, 2, or 3. (This scenario is included for illustrative purposes only.)
