GeoJSON

GeoJSON is an <a href="/facts/Open_standard/RGvhGQVI">open standard</a> format designed for representing <a href="/facts/Simple_Features/R8bwfcrs">simple geographical features</a>, along with their non-spatial attributes. It is based on the <a href="/facts/JSON/bs1rUAhd">JSON</a> format.
The features include points (therefore addresses and locations), <a href="/facts/Polygonal_chain/GRQ6BMQS">line strings</a> (therefore streets, highways and boundaries), <a href="/facts/Polygon/xvkmYhvG">polygons</a> (countries, provinces, tracts of land), and multi-part collections of these types. GeoJSON features are not limited to representing entities of the physical world only; mobile routing and navigation apps, for example, might describe their service coverage using GeoJSON.
The GeoJSON format differs from other <a href="/facts/Geographic_information_system/PoP1kVoa">geographic information system</a> standards in that it was written and is maintained not by a formal standards organization, but by an Internet working group of developers.
A notable offspring of GeoJSON is TopoJSON, an extension of GeoJSON that encodes <a href="/facts/Geospatial_topology/NKQtdEqa">geospatial topology</a> and that typically provides smaller file sizes.
