Once the basic registration of images to landmarks are done, then it usually is time to do batch updating of the topography, what is typically called "iterating". There are several different templates that can be used (known as seeds). They usually contain variations of using stereo, number of passes, limbs and/or existing topography.
This procedure will get a list of landmarks to work on, build the scripts that LITHOSP (the parallel version of LITHOS) will run, start the scripts and monitor them.
1 - Choose a set of landmarks to process. Typically, we just copy LMRKLIST.TXT to make_script.in.
2 - Ensure the fast lookup table is updated by running MAKE_LMRKLISTX to form MAKE_LMRKLISTX.TXT. This file has every landmark in it, plus location data added. This lets LITHOS identify the boundaries much faster.
3 - Copy one of the seed files to be used. It is stored in the SPC directory under SEEDS. It is copied into the standard name make_scriptP.seed. make_scriptP uses that file to generate the run_script files
4 - Edit make_scriptP.seed to make sure it is what you want. The most likely thing is to comment out the "v" option. The "v" option will update the spacecraft pointing, which you might not want to do at this time.
5 - Generate the run_script files. Run the command make_scriptP. It will generate numerous make_scriptXX.b files (b is for batch -- nonstandard notion for a shell script). It will also display a set of commands that you need to run. You can retype them into a shell, copy and paste them, or direct their output to form a short shell program that you run next (which is what I normally do).
6 - Execute the output from make_scriptP.
7 - Monitor using find_nofitP
Basic instructions from testing procedures
For this procedure, we will use the entire list of landmarks -- so we are processing the entire surface. cp LMRKLIST.TXT make_script.in /usr/local/bin/MAKE_LMRKLISTX Set up the seed file cp <SPC Source>/SEEDS/Piterate2.seed make_scriptP.seed Generate the scripts (This makes the scripts and also outputs several commands to run the scripts to standard output) /usr/local/bin/make_scriptP > run.sh Run the scripts (this will execute the shell commands) sh run.sh Monitor progress /usr/local/bin/find_nofitP It will generate output that shows the progress and landmarks with problems. If the landmark has a leading *, then there is a serious problem that must be fixed. Try to align the landmarks by hand, or try methods suggested by "Problems".
