- 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).

A GeoJSON File is an open geospatial data format that is interchangeable, and it represents standard geographic attributes and their nonspatial qualities. It gets its motivation from the JavaScript Object Notation (JSON) and it is used to encode an assortment of geographic data structures.
The units used in this format are the decimal degrees, and it primarily uses the system of geographic coordinate reference. The GeoJSON format is used to define objects such as buildings, roads, water bodies, and other similar points of interest. It supports different geometry including multi-polygon, multiline string, polygon, and string. This format differs from GIS standards because developers who were an internetworking group wrote it.
This format is also used to describe mobile routing where it is unnecessary to have physical points or bodies. This is an additional development that was added to make the entire format more effective. The addition resulted from the improvements in technology where mobile routing was taking over and a reliable mapping system was necessary.
There have been several extensions that were developed from this format with the most notable one being TopoJSON. It provides smaller files, but it still uses the same concept as its mother format.
