The WKT 1 and WKT 2 formats are incompatible regarding coordinate operations, because of differences in the modelling. [13] Below is an example of a concatenation of two WKT 1 transformation descriptions, where the Mercator projection is applied first and then an affine transform is applied on the result:
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 ...
Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator[ 1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications. It rose to prominence when Google Maps adopted it in 2005. [ 2] It is used by virtually all major online map providers, including Google ...
Geodesy. EPSG Geodetic Parameter Dataset (also EPSG registry) is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement, originated by a member of the European Petroleum Survey Group (EPSG) in 1985. Each entity is assigned an EPSG code between 1024 and 32767 ...
OpenStreetMap ( OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result ...
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 ...
OpenStreetMap Foundation. / 52.55098; -1.81860. The OpenStreetMap Foundation (abbreviated OSMF) is a non-profit foundation whose aim is to support and enable the development of freely-reusable geospatial data. Founded in 2006, it is closely connected with the OpenStreetMap project, although its constitution does not prevent it supporting other ...
Method 2: Using the OpenStreetMap website. After right-clicking the shape you want to map (for instance, Scioto Audubon Metro Park), click 'Query features' to bring up the lefthand toolbar. Select the feature name to bring up its relation. Go to OpenStreetMap and zoom into the general area where the shape is.
