What's Changed
This release improves performance and reduces memory requirements:
- Generating a map of the world on a high-end machine (64 cpu/128GB RAM) now takes as little as 47 minutes instead of an hour
- You can now run with as little as 32GB of RAM instead of 128 using
--storage=mmapto store temporary data in memory-mapped files
To run this release from Java, download the attached planetiler.jar, or from docker use ghcr.io/onthegomap/planetiler:0.4.0.
There is ongoing discussion about the project in the #planetiler channel on OSM-US slack. If you are interested in joining, get an invite here!
