It is the most popular way to display and navigate maps, replacing other methods such as ...
Contents. Leaflet (software) Leaflet is a JavaScript library used to build web mapping applications. It allows developers without a GIS background to display tiled web maps hosted on a public server, with optional tiled overlays. It can load feature data from GeoJSON files, style it and create interactive layers, such as markers with popups ...
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. The TMS protocol fills a gap between the very simple standard used by OpenStreetMap and the complexity of the Web Map Service standard ...
Website. www.ogc.org /standards /wms. A Web Map Service (WMS) is a standard protocol developed by the Open Geospatial Consortium in 1999 for serving georeferenced map images over the Internet. [1] These images are typically produced by a map server from data provided by a GIS database. [3]

It rose to prominence when Google Maps adopted it in 2005. [2] It is used by virtually all major online map providers, including Google ...
