Traffic API Developer's Guide

Selecting a Tile Size

The user wants to obtain a traffic tile for an area near Frankfurt Germany, using the [Z]/[X]/[Y] addressing scheme.

The request follows the same pattern as requests for traffic flow tile overlays, but requires the res parameter to select the tile size and/or depth to determine the required color depth.


The [Z]/[X]/[Y] values are 8, 134, and 86 respectively. The resolution (size) is 512x512 pixels and the format is png32. Alternatively, you can also specify a resolution of 256x256 pixels or 128x128 pixels.


The image below shows the tile delivered in response to the request.
