Nine case-sensitive strings: "Feature", "FeatureCollection", and O As another shorthand notation, the term "GeoJSON types" refers to "MultiLineString", "Polygon", "MultiPolygon", and O Inside this document, the term "geometry type" refers to sevenĬase-sensitive strings: "Point", "MultiPoint", "LineString", Name, value, array, number, true, false, and null, are to be ![]() O JavaScript Object Notation (JSON), and the terms object, member, This document supersedes the original GeoJSON format specification Illustrate the data structures, but it is not required. Whitespace is used in the examples inside this document to help Validate the corresponding JSON code example. These placeholders must ofĬourse be deleted or otherwise replaced, before attempting to (//) followed by an ellipsis (.) as placeholder notation forĬontent deemed irrelevant by the authors. Some examples use the combination of a JavaScript single-line comment The ordering of the members of any JSON object defined in thisĭocument MUST be considered irrelevant, as specified by. "OPTIONAL" in this document are to be interpreted as described in "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", JavaScript web-mapping libraries, JSON-based document databases, and Specification has steadily grown in popularity. Since its initial publication in 2008, the GeoJSON format GetFeature requests, but there is no particular service model orįeature type ontology implied in the GeoJSON format specification. Of the WFS specification also provide GeoJSON-formatted responses to GetFeatures requests specified in or to a Keyhole Markup This structure isĪnalogous to that of the Web Feature Service (WFS) response to 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). GeoJSON is a format for encoding a variety of geographic data Semantics of GeoJSON Members and Types Are Not Changeable 16Ĩ. The Trust Legal Provisions and are provided without warranty asġ.
