The Tile Map Widget displays tile-based maps from a server that conforms to the Open Street Maps architecture.

This Widget provides advantages over the Vector Map Widget because it can show details such as streets and satellite imagery. The Widget also provides advantages over the Google Map Widget, because it does not require an internet connection and is not reliant upon the Google mapping technology and data.

As in other AppBoard map Widgets, the data source for the Widget must contain fields with Longitude and Latitude for each node to be drawn on the map.
