It reads PBF files and imports the data into PostgreSQL/PostGIS. It can also automatically update the database with the latest changes from OSM. It is designed to create databases that are optimized for rendering (i.e. generating tiles or for WMS services). The development of Imposm is sponsored by Omniscale. Imposm is in production use by the authors. It is actively maintained, with a focus on resolving future incompatibilities with dependencies such as PostGIS. However, there is no capacity for end-user support, and no new features will be developed beyond its existing scope. Features -------- High-performance Diff support Custom database schemas Generalized geometries In detail - High performance: Parallel from the ground up. It distributes parsing and processing to all available CPU cores. - Custom database schemas: Creates tables for different data types. This allows easier styling and better performance for rendering in WMS or tile services. - Unify values: For example, the boolean values 1 , on , true and yes all become TRUE . - Filter by tags and values: Only import data you are going to render/use. - Efficient nodes cache: It is necessary to store all nodes to build ways and relations. Imposm uses a file-based key-value database to cache this data. - Generalized tables: Automatically creates tables with lower spatial resolutions, perfect for rendering large road networks in low resolutions. - Limit to polygo","default_branch":null,"files":null,"tree":[],"storefront":"/r/omniscale","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/omniscale/imposm3/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
