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 formats were originally defined by the Open ...
Later, evolution of the Coordinate Reference System conceptual model, new requirements and inconsistencies in implementation of WKT 1 format between different software have encouraged the revision of that format. The updated "Well-known text representation of coordinate reference systems" standard, sometime known as "WKT 2", was adopted by the ...
Standard. ISO 19136:2007. 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.
GIS file format. A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes.
Simple Features. Simple Features (officially Simple Feature Access) is a set of standards that specify a common storage and access model of geographic features made of mostly two-dimensional geometries (point, line, polygon, multi-point, multi-line, etc.) used by geographic databases and geographic information systems .
GeoSPARQL is a model for representing and querying geospatial linked data for the Semantic Web.It is standardized by the Open Geospatial Consortium as OGC GeoSPARQL. The definition of a small ontology based on well-understood OGC standards is intended to provide a standardized exchange basis for geospatial RDF data which can support both qualitative and quantitative spatial reasoning and ...
Well-Known Text (WKT) is a name of format forged by OGC, not some general term for parenthesis-wrapped tagged lists of coordinates. The fact that some software handle degenerate form of format is no reason to display it in the article devoted to OGC Well-Known Text. Any non-standard implementation-specific variant should be simple removed or ...
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products. [ 1] The shapefile format can spatially describe vector features: points, lines, and polygons ...
