Apache Baremaps simplifies the process of creating, publishing, and operating online maps by providing a toolkit and infrastructure components. You can easily consolidate your spatial datasets in PostGIS by creating custom data pipelines using Baremaps, which supports several popular formats such as OsmPbf, ShapeFile, GeoPackage, and FlatGeoBuf to integrate with your existing workflows. You can also serve and publish custom vector tiles from PostGIS for web or mobile applications with Baremaps. The toolkit even provides a geocoder that allows you to search for places and addresses. Apache Baremaps welcomes contributions and is experimenting with new components to improve the quality of its services.
