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 )
GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. 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.
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.
The actual shapefile relates specifically to the .shp file, but alone is incomplete for distribution as the other supporting files are required. In line with the ESRI Shapefile Technical Description , [ 1 ] legacy GIS software may expect that the filename prefix be limited to eight characters to conform to the DOS 8.3 filename convention ...
The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation.
Vector tiles, tiled vectors or vectiles [1] are packets of geographic data, packaged into pre-defined roughly-square shaped "tiles" for transfer over the web. This is an emerging method for delivering styled web maps, combining certain benefits of pre-rendered raster map tiles with vector map data.
Well-known text (WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary (WKB), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable.
The Geography Markup Language (GML) is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet.
