Tiled web map

A tiled web map, slippy map (in OpenStreetMap terminology) or raster tile map is a map displayed in a browser by seamlessly joining dozens of individually requested image files over the internet. It is currently the most popular way to display and navigate maps, replacing other methods such as WMS which typically display a single large image, with arrow buttons to navigate to nearby areas. Google Maps was one of the first major mapping sites to use this technique. Tiled web maps may in turn be replaced by vector tiles as the standard.
