Image map. In HTML and XHTML, an image map is a list of coordinates relating to a specific image, created in order to hyperlink areas of the image to different destinations (as opposed to a normal image link, in which the entire area of the image links to a single destination). For example, a map of the world may have each country hyperlinked ...
The geo URI scheme is a Uniform Resource Identifier (URI) scheme defined by the Internet Engineering Task Force 's RFC 5870 (published 8 June 2010) [1] as: a Uniform Resource Identifier (URI) for geographic locations using the 'geo' scheme name. A 'geo' URI identifies a physical location in a two- or three-dimensional coordinate reference ...
The polygonal map quadtree (or PM Quadtree) is a variation of quadtree which is used to store collections of polygons that may be degenerate (meaning that they have isolated vertices or edges). [ 9 ] [ 10 ] A big difference between PM quadtrees and edge quadtrees is that the cell under consideration is not subdivided if the segments meet at a ...
The Maidenhead Locator System (a.k.a. QTH Locator and IARU Locator) is a geocode system used by amateur radio operators to succinctly describe their geographic coordinates, which replaced the deprecated QRA locator, which was limited to European contacts. [ 1] Its purpose is to be concise, accurate, and robust in the face of interference and ...
Online application to acquire coordinates for any place on Earth. Supports more than 3,000 coordinate systems and 400 datums worldwide. Place pushpins on the map and calculates automatically the coordinates in the selected coordinate system or datum. Perform transformation between coordinate systems and/or datums.
Hypixel, officially the Hypixel Network, is a Minecraft server that hosts minigames. It was released on April 13, 2013 by Simon "Hypixel" Collins-Laflamme and Philippe Touchette, and is managed and run by Hypixel Inc. [4] [better source needed] Hypixel is only available on the Java Edition of Minecraft, [5] but briefly had a Bedrock variant.
The W3C Geolocation API is an effort by the World Wide Web Consortium (W3C) to standardize an interface to retrieve the geographical location information for a client-side device. [3] It defines a set of objects, ECMAScript standard compliant, that executing in the client application give the client's device location through the consulting of ...
Geohash. The 6g cell and its sub-grid. Geohash is a public domain geocode system invented in 2008 by Gustavo Niemeyer [ 1] which encodes a geographic location into a short string of letters and digits. Similar ideas were introduced by G.M. Morton in 1966. [ 2] It is a hierarchical spatial data structure which subdivides space into buckets of ...
