Abstract
Some embodiments provide a mapping application for rendering map portions. The mapping application includes a map receiver for receiving map tiles from a mapping service in response to a request for the map tiles needed for a particular map view. Each map tile includes vector data describing a map region. The mapping application includes a set of mesh building modules. Each mesh building module is for using the vector data in at least one map tile to build a mesh for a particular layer of the particular map view. The mapping application includes a mesh aggregation module for combining layers from several mesh builders into a renderable tile for the particular map view. The mapping application includes a rendering engine for rendering the particular map view.
