planetiler

Overview

Planetiler is an open-source Java project hosted on GitHub under the Apache-2.0 license. It is designed to generate vector tiles (in the widely used .mbtiles or other formats) from large geospatial datasets such as OpenStreetMap (OSM) and Overture Maps. The project focuses on speed and low memory usage, enabling developers to produce a full planet-scale vector tile set in a fraction of the time required by traditional pipelines. With over 2,100 GitHub stars, Planetiler has gained traction among mapping engineers, GIS developers, and independent product teams who need to build or self-host custom map layers. The project is actively maintained and accepts contributions through its GitHub repository at github.com/onthegomap/planetiler.
