Map Tile API Developer's Guide

Key Concepts

This section provides information intended to help you understand and use the Map Tile API.

Requesting the Correct Map Version

The API offers maps that are updated on a regular basis. You can request the newest map or a specific version. For more details on how to request the map version that you require, see Map Versions.

Mercator Projection

The API serves map tiles obtained by mapping points on the surface of a sphere (the globe) to points on a plane, using the normalized Mercator projection. For more information, see Mercator Projection.

Load Balancing Requests

The API is optimized for load balancing. You can use this feature to improve response times when you need to submit multiple requests simultaneously. For more information, see Load Balancing and URLs.
