Baremaps is a toolkit for creating custom vector tiles from OpenStreetMap and other data sources with Postgis and Java. The project is licensed under Apache License 2.0.

Baremaps is inspired by Osmosis, but it comes with additional features, such as the ability to:

• Process data in parallel with the Stream API introduced in Java 8
• Import data faster with the COPY API of Postgresql
• Create postgis geometries on the fly with JTS
• Create and serve customized Mapbox Vector Tiles

On the longer run, the aim of the project is to work with a variety of data sources in order to create highly specialized and customized maps.

• To contribute to this repo see CONTRIBUTING and CODE_OF_CONDUCT.
• To build baremaps. You'll need maven and Java 11.
• cd baremaps-cli && mvn package -P maputnik -B. This creates a .zip in the target folder.
• alternatively you can build a docker image with mvn jib:dockerBuild -DskipTests.
