The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.
GeoJSON – open, lightweight format based on JSON, used by many open source GIS packages GeoMedia – Microsoft Access based format for spatial vector storage (by Intergraph ) ISFC – MicroStation based CAD solution attaching vector elements to a relational Microsoft Access database (by Intergraph )
JSON has several types built-in and has a similar schema concept in JSON Schema. ... GeoJSON, a format designed for representing simple geographical features [65] [66]
Other formats, such as GeoJSON, use different structures for geometry and attributes, but combine them for each object in the same file. Geospatial topology is often an important part of vector data, representing the inherent spatial relationships (especially adjacency) between objects. Topology has been managed in vector file formats in four ways.
JSON streaming comprises communications protocols to delimit JSON objects built upon lower-level stream-oriented protocols (such as TCP), that ensures individual JSON objects are recognized, when the server and clients use the same one (e.g. implicitly coded in). This is necessary as JSON is a non-concatenative protocol (the concatenation of ...
Run the query, then click 'Export' in the toolbar and select the 'copy' part of 'download/copy as GeoJSON' In Wikimedia Commons, create a page in the Data: namespace with the .map extension, like Data:COTA10.map; When you create the page, replace the 'Data' placeholder (including the two brackets) with the GeoJSON you copied.
data stored in GeoJSON format on Wikipedia or Commons; line/polygon features in OpenStreetMap. coordinates, either supplied or from Wikidata; raw GeoJSON, preferably transcluded from another page; Note: If you have a very large/slow map, you should use the mapframe extension tag directly instead of this template, as was done in Special:Diff ...
GeoJSON map data cannot be directly uploaded and stored in the File namespace. While map data should usually be stored on Commons (see mw:Help:Map data), until August 2018 only CC0 licences were not allowed. Because of this former restriction, this process was set up so that data with licences compatible with Wikipedia's CC-BY-SA-3.0 licencing ...
