  5. This document describes a mapping from OSM data formats to the usual GIS formats to make the OSM data accessible to more people. The mapping from OSM data to other formats is not an exact science.

  7. OSM looks to map ALL visible physical objects such as: points of interest, roads, buildings, transportation systems, land use, social facilities such as health, education, government, law, shops, industry, water systems, sanitation systems, energy systems, environmental features.
