Tiled Web Map Support

A tiled web map, (often termed a slippy map^[1] )  is a map displayed in a browser or other application by seamlessly joining dozens of individually requested image files over the internet or intranet.

It is 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.

O-Calc Pro supports a number of tiled map servers.

To minimize network traffic it may be best to deploy a map tile server on-premises but cloud hosted servers are also supported.  Most GIS systems support Slippy Map tile serving.
