About the Map Tiling Service
About the Map Tiling Service
The Map Tiling Service dynamically generates subsets of a map on a per-request basis. This subset is
called a tile. The tiles generated from the Map Tiling Service can be used individually, or combined to
form larger maps, in applications for seamless map interaction. This service provides fast, simple, lightweight
map rendering where more complex map rendering can be performed using the Presentation
Service.
The Map Tiling Service allows the hosting of multiple maps that can be used to generate the tiles. These
named maps are located in one or more map repositories. Each map hosted by the Map Tiling Service
can have a specific configuration that defines how the map will be used to create tiles.
The Map Tiling Service has two interfaces. Both are web based HTTP interfaces, however, one is a
REST interface, and the other is a name/value pair interface:
• REST - Referred to as the Map Tiling REST interface, this API is a simplified web interface that has
methods for getting the name of maps, describing maps, and getting tiles. For details of this REST
interface, see Map Tiling REST Interface on page 19 for more information.
• Name/Value - Referred to as the Legacy Map Tiling interface, this API provides more complex methods
that include the REST methods as well as methods for getting the bounds of maps, level descriptions
tile sets, and numerous conversion methods between pixel, tile, and screen coordinates.
Note:
This is a legacy interface, and should only be used to support PBBI backwards compatable
applications. For all new applications, use the REST interface.
For details of this interface, see Legacy Map Tiling Interface on page 27 for more information.
Supported Data
Both vector and raster data can be hosted by the Map Tiling Service.
Named Map Modifications
6
The Map Tiling Service is designed to host your maps without modification. However, due to the dynamic
nature of tile generation, the Map Tiling Service does make minor modifications to the map after it is
loaded into the server. These changes relate to the rendering of labels, and are as follows:
• Duplication of labels is not allowed.
• Geometry calculation mode is set to STATIC.
• Partial labels are allowed.
A special category of layers relate to the display of highway shields. To allow the accurate display of
highway shield layers the following label properties are set:
• Duplication of labels is allowed.
• Geometry calculation mode is set to STATIC.
• Partial labels are allowed.
These modifications are stored in the Map Tiling Service memory and in no way change the source of
the maps hosted by the Map Tiling Service stored in the repository.
