Map Tile Layer Properties Dialog Box, General
Select General on the Map Tile Layer Properties dialog box to change display options. Unlike polygon, line, and point layers, you do not specify the spatial data for a tile layer. Tiles are automatically retrieved from Bing Maps Web Services when the following conditions are true:
The viewport coordinate system is Geographic.
The projection is Mercator.
When you are viewing a report from a report server, the report server has been configured to support a Bing map tile background for a map.
When you are in local preview, you have internet access and Bing Maps Web Services is available.
Specify these options on the Map Viewport Properties Dialog Box, General dialog box.
