Imposm Publisher's description
from Oliver Tonnhofer
Imposm is an importer for OpenStreetMap data....
Imposm is an importer for OpenStreetMap data. It reads XML and PBF files and can import the data into PostgreSQL/PostGIS databases.
It is designed to create databases that are optimized for rendering/WMS services.
It is developed and supported by Omniscale, runs on Linux or Mac OS X and is released as open source under the Apache Software License 2.0.
Custom database schemas
It creates tables for different data types. This allows easier styling and better performance for rendering in WMS or tile services.
Multiple CPU/core support
Impsom is parallel from the ground up. It distributes parsing and processing to multiple CPUs/cores.
For example, the boolean values 1, on, true and yes all become TRUE.
Filter by tags and values
It only imports 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 (Tokyo Cabinet) to cache this data. This reduces the memory usage.
It can automatically create tables with lower spatial resolutions, perfect for rendering large road networks in low resolutions for example.
It can create views that combine multiple tables.
