Planina Konjš?ica

I have just generated Garmin maps for Slovenia using GroundTruth. Here are some performance results (my machine is Intel E6400, 4 GB RAM):

  • Source OSM data: 330 MB OSM file (non-compressed)
  • Time to generate: 8 minutes
  • Maximum RAM usage: 1.1 GB

This is for the hiking map which currently contains more rules than the driving map (driving map generation took “only” 3 minutes). The actual performance bottleneck is cgpsmapper, most of the time and memory consumption is caused by it. If you’re planning to generate even larger maps, I suggest splitting OSM files (using tools like osmosis) before giving them to GroundTruth. You can generate multiple IMG files by supplying several OSM files in a comma-separated list.
