Object contains an array of Feature objects. GeoJSON also comprises the types Feature and FeatureCollection.įeature objects in GeoJSON contain a Geometry object with one of theĪbove geometry types and additional members. Instances of these geometry types are analogous to the well-knownīinary (WKB) and well-known text (WKT) representations described in OpenGIS Simple Features Implementation Specification for SQL :Ġ-dimensional Point and MultiPoint 1-dimensional curve LineStringĪnd MultiLineString 2-dimensional surface Polygon and MultiPolygon Īnd the heterogeneous Geometr圜ollection. GeoJSON comprises the seven concrete geometry types defined in the Geographic information system standards and have been streamlined toīetter suit web application development using JSON. In GeoJSON are not new they are derived from preexisting open The format is concerned with geographic data in the broadest sense Īnything with qualities that are bounded in geographical space mightīe a Feature whether or not it is a physical structure. Geometry object and additional properties, and a FeatureCollection Point, LineString, Polygon, MultiPoint, MultiLineString, GeoJSON supports the following geometry types: Spatially bounded entity (a Feature), or a list of Features (aįeatureCollection). GeoJSON object may represent a region of space (a Geometry), a Structures using JavaScript Object Notation (JSON).
