Description
A GeoJSON file is a format for encoding a variety of geographic data structures using JavaScript Object Notation (JSON). It is a widely used open standard format designed for representing simple geographical features, along with their non-spatial attributes. GeoJSON supports various geographical data types such as points, lines, polygons, and multi-part collections of these types. It is commonly used for storing and exchanging spatial data on the web, as well as within various Geographic Information Systems (GIS).
An OSM file contains street map information in the OpenStreetMap (OSM) format. It saves XML-formatted data in the form of "nodes" (points), "ways" (connections), and "relations" (street and object properties, such as tags).
