data format in the OSM project. 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. OSM rules on how to map certain features are often not well defined and there is no mandatory quality control.
In this section we’ll go through a few ways of storing geographic data, explain how they work and how they’re typically used. The .osm file format is specific to OpenStreetMap. You won’t come across it elsewhere. If you have ever downloaded data using JOSM and saved it as a file, you may have noticed that the file is saved with the extension .osm.
OSM users aim to achieve this goal by gathering geographic data from government open data portals, GPS devices, digitizing aerial imagery or using paper maps. This tutorial will involve searching and extracting three amenity types (restaurants, hospitals, schools).
