Export and Import

(Modified by JRW from text written by EEP)

These two programs will allow you to export landmarks from multiple machines, which can then be added to another machine. Instead of merging two or more datasets, a similar end result is achieved by adding all landmarks to a "main" or "head" machine.

While this is useful for combining data from multiple users, it was originally intended to be a tool which would allow someone to tile an object/bigmap simultaneously on multiple machines, then combine the results onto a single machine. Hence it uses LMRKLIST1.TXT, which is a list of newly added landmarks.

Export

We generate a script that will copy the new landmarks and put them into a tar ball. Makes EXPORT.B and the script EXPORT.TXT. If you notice, EXPORT.TXT will run the script EXPORT.B. The key thing you need to ensure is that LMRKLIST1.TXT only has the recently created landmarks. If it has older ones, then you might need to trim the top of the file. You should also ensure that there aren't any maplets or landmarks remaining in NEW_FILES. If NEW_FILES does not exist, you will need to create NEW_FILES, as well as NEW_FILES/LMKFILES and NEW_FILES/MAPFILES. 

/usr/local/bin/EXPORT

This will create the directory NEW_FILES and populate it with copies of the newly created mapfiles and landmarks.

The script EXPORT.TXT looks this, but you don't need to understand it to use it: 

 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

and transfer the tar file to the other computer.

Import

Untar to recover NEW_FILES directory. If you didn't rename the tar file, from the working directory all you need to do is type... 

tar -xf NEW_FILES.TAR

/usr/local/bin/IMPORT
