This is what we are currently doing for Bob for Vesta (Nov 2011). Original powerpoint: tiling.ppt

I am making suggestions to improve and streamline things. First, I have created a directory called "work_general" (about 3GB) that is in the ~/Dropbox/Dawn-shape directory. This directory has all the files needed to do the tiling (landmarks, mapfiles and supporting files). Copy this to your own computer for each processor that you are going to use. Then run the script setup.sh, which will create symbolic links to the ~/Dropbox/Dawn-shape/Vesta directory (specifically the image files). This avoids copying 12GB of data that won't change. Eventually, we can put in an "rsync" command that will keep our working directories up to date with the master dropbox directory.

Look Around

First we need to see where we need new maplets. We run map_coverage.e:

 ~/bin/map_coverage.e
 ZS1000
 0,.1      ←     min,max resolution

And look at the output coverage_m.pgm. Use graphics converter or imagemagik

 convert coverage_m.pgm coverage_m.jpg

The bottom part has already been tiled from ZS1200 and ZS1203.

Run

We need to ensure all the old files are removed from previous runs.Before running type:

 rm LMRKLIST1.TXT 

Then to clean up old stuff, build the scripts and run them, make_scriptT.e

sh rem_script.b
rm TESTFILES/*
rm TESTFILES1/*
~/bin/make_scriptT.e
chmod +x run_script.b 
./run_script.b &

It seems to take about 2 minutes per landmark. We are currently generating 361 landmarks, which works out to 10 to 12 hours to finish.

Type this from time to time to see how it is going, find_nofitT.e.

~/bin/find_nofitT.e

Export

We generate a script that will remove unneeded files and take the new landmarks and put them into a tar ball. Makes EXPORT.b and the script EXPORT.TXT, map_coverage.e

~/bin/EXPORT.e

The script EXPORT.TXT is:
 cp LMRKLIST1.TXT NEW_FILES/LMRKLIST.TXT
 cd NEW_FILES/LMKFILES
 rm -f *.LMK
 cd ../..
 cd NEW_FILES/MAPFILES
 rm -f *.MAP
 cd ../..
 chmod +x EXPORT.b
 ./EXPORT.b
 tar -cf NEW_FILES.tar NEW_FILES
 rm -f LMRKLIST1.TXT

Run this script by

sh EXPORT.TXT

Change name of NEW_FILES.tar to something distinctive like

• NEW_FILES_ZS1000.tar

and e-mail to me or put in dropbox.

Import

Untar to recover NEW_FILES directory, importl.e

~/bin/IMPORTL.e

cp NEWLIST.TXT make_script.in

For make_scriptF.seed use:

n
n
g
u
1
o
RECENT
n
1
q
END

Run these commands (copy into window)

sh rem_script.b
rm TESTFILES/*
rm TESTFILES1/*
~/bin/make_scriptF.e
./run_script.b &

Type this from time to time to see how it is going, importl.e.

~/bin/find_nofitT.e  (this didn't seem to work, but find_nofitP.e gave output that made sense)
