Leaflet supports Web Map Service (WMS) layers, GeoJSON layers, Vector layers and Tile layers natively. Many other types of layers are supported via plugins.. Like other web map libraries, the basic display model implemented by Leaflet is one basemap, plus zero or more translucent overlays, with zero or more vector objects displayed on top.
OpenStreetMap (abbreviated 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 photo imagery or satellite imagery, and also import from other freely licensed geodata sources.
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 projects.
[26] [27] The technology is based on Node.js, [28] Mapnik, GDAL, and Leaflet. Mapbox uses anonymized data from telemetry pings, such as Strava and RunKeeper, to identify likely missing data in OpenStreetMap with automatic methods, then manually applies the fixes or reports the issue to OSM contributors.

Geovisualization is closely related to other visualization fields, such as scientific visualization [1] and information visualization. [2] Owing to its roots in cartography, geovisualization contributes to these other fields by way of the map metaphor, which "has been widely used to visualize non-geographic information in the domains of information visualization and domain knowledge ...
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 idea to create the Missing Maps project was born out of a realisation by the American Red Cross, British Red Cross, Humanitarian OpenStreetMap Team, and Médecins Sans Frontières that maps are pivotal to delivering humanitarian aid. [3]
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 which attempts to fulfill REST principles.
