onthegomap/planetiler v0.7.0

on GitHub

What's Changed

This release reduces openmaptiles tile sizes by 40-50% and includes tools other profiles can use to use to optimize their tile sizes:

• --max-point-buffer=4 argument to remove points outside the tile boundary if your client handles label collisions between tiles (web/native but not raster)
• --output-layerstats to write a layer stats tsv.gz file you can analyze with duckdb to look for improvements
• FeatureMerge Utilities to to merge geometries with the same attributes into multigeometries. See openmaptiles/planetiler-openmaptiles#112 which applies these improvements to openmaptiles profile for close to 90% savings on some dense housenumber/building layers.

This release also adds support for writing plugins in other languages to send tiles to other data stores. See #639 for examples of how to write to mysql, postgres, or s3.

⚠️ This will be the last release with Java 17 support, the next release will target Java 21. Upgrade now to avoid any interruptions! ⚠️

To run this release from Java, download the attached planetiler.jar, or from docker use ghcr.io/onthegomap/planetiler:0.7.0

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!
