On sunday, 2008-11-02, evening, I again restarted the script which creates the heightlines. Why? Heck, it seems that the used file system (vfat) limits the amount of files per folder. My code reported “Disk full”, while there was still space available on the disk. After some trial and error, I jsut reformatted the drive, but using an ext3 file system this time. How should I say? Finally, it’s up and running since then now.
I partitioned the world into 4 quadrants, processing each of them at the very same time, to feed my cores. As of this writing, the 4th quadrant
inc=1; for y in $(seq -90 $inc -90); do for x in $(seq -180 $inc 179); do mono /home/OSM-Planet/srtm2osm/srtm2osm/bin/Srtm2Osm.exe -bounds1 $y $(($x+0.00001)) $(($y+$inc)) $(($x+$inc)) -large -step 40 -cat 1000 200 -o “borders/Lat$(echo $y)Lon$(echo $x)Lat$(($y+$inc))Lon$(($x+$inc)).osm”; done; done
already is finished. But the others are still very busy, and currently 43697 out of 64800 tiles have been processed. I cannot predict how long the rest will last, but hope to finish this run before sunday. After that, I’ll restart from scratch, creating a second set of data. Instead of 40, 200 and 1000m steps, it will contain 100, 500 and 1000m steps.
