A mapping application for OpenStreetMap that renders OSM or MapQuest tiles and does basic routing from a built-in database.

The main focus of this project is the development of a high-performance routing engine that can handle a variety of routing and vehicle constraints on demand without additional pre-processing of the road network. An additional goal is the development of a class library centered around a built-in, object-oriented database used for processing and storing OSM map data such that external dependencies (e.g. external database servers) are minimized.
