A tiled web map, slippy map [1] (in OpenStreetMap terminology) or tile map is a map displayed in a web browser by seamlessly joining dozens of individually requested image or vector data files. It is the most popular way to display and navigate maps, replacing other methods such as Web Map Service (WMS) which typically display a single large ...
The GDA94 datum was formalized in 1994, replacing the previous datums which were being used in Australia at the time, the Australian Geodetic Datum 1966 (AGD66) and the Australian Geodetic Datum 1984 (AGD84). Prior to 1966, maps in Australia were produced in miles using the Australian National Grid. [2]
The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.
UTM zones on an equirectangular world map with irregular zones in red and New York City's zone highlighted. The first part of an MGRS coordinate is the grid-zone designation. The 6° wide UTM zones, numbered 1–60, are intersected by latitude bands that are normally 8° high, lettered C–X (omitting I and O).
This is an emerging method for delivering styled web maps, combining certain benefits of pre-rendered raster map tiles with vector map data. As with the widely used raster tiled web maps, map data is requested by a client as a set of "tiles" corresponding to square areas of land of a pre-defined size and location. Unlike raster tiled web maps ...
Tile Map Service or TMS, is a specification for tiled web maps, developed by the Open Source Geospatial Foundation. The definition generally requires a URI structure ...

These tiles are rendered on the client side by a library such as the Mapbox Maps SDK, MapLibre, Mapzen's Tangrams, or OpenLayers. Applications such as Mapbox Studio allow designers to author vector styles in an interactive, visual environment. [84] Vector maps are especially common among three-dimensional mapping applications and mobile ...
