GeoJSONi

GeoJSON is an open standard format designed for encoding a variety of geographic data structures. It is based on JavaScript Object Notation (JSON), a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. GeoJSON is widely used in web mapping applications and geographic information systems (GIS) due to its simplicity and compatibility with web technologies.

The GeoJSON format supports several types of geometric objects, including Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. Each geometric object is represented as a JSON object with a specific set of properties. For example, a Point is represented as a JSON object with a "type" property set to "Point" and a "coordinates" property that is an array of two numbers representing the longitude and latitude.

GeoJSON also supports the representation of non-geometric data, such as properties associated with geometric objects. These properties are represented as key-value pairs in the JSON object. For example, a Point representing a city might have properties such as "name" and "population".

GeoJSON is designed to be simple and flexible, allowing for the representation of complex geographic data structures in a compact and efficient manner. It is widely supported by web mapping libraries and GIS software, making it a popular choice for sharing and exchanging geographic data on the web.
