The OpenStreetMap data model. The OSM data model consists of two principal elements: nodes and ways. A node represents a single point, identified by its latitude and longitude. A way is an ordered list of nodes, forming a polyline. A way that is closed (its start and end node are the same) can be used to form a simple polygon.
OpenStreetMap foremost contains three kinds of data: Geometries, more precisely coordinates and references to the coordinates, locate the objects on Earth's surface. Short bits of text giving each object a semantical meaning. Meta data facilitates to attribute the sources to the data.
