RoadMap 1.0.12p2

A GPL car navigation system for Pocket PCs

RoadMap is an open source (GPL) program that provides a car navigation for Linux, UNIX and now Windows CE (a.k.a. PocketPC). It displays a map of the streets, tracks the position provided by a NMEA-compliant GPS receiver, identifies the street matching this GPS position and announces the name of the crossing street at the next intersection. A rudimentary trip feature allows RoadMap to display some basic navigation information (distance to the destination, direction, speed, etc..). Voice messages are generated that duplicate some of the screen information.

It is possible to display a specific area by providing a (complete or incomplete) postal address, the intersection of two streets or an exact position (longitude / latitude).

The map files used by RoadMap are generated from the TIGER files provided by the US Census Bureau, and thus cover the USA only. The RoadMap map format is a binary format that is sensitive to the endianness of the processor. Maps available on this site cover all the USA and have been generated for a little endian processor (such as the Intel Pentium and StrongARM processors).

RoadMap is at an early stage of development. At this time there are no routing features implemented yet. The plan for the future is to implement some navigation features similar to those found in commercial street navigation systems. The main limit for implementing routing is the lack of navigation information in the US Census Bureau database (for example one-way street are not indicated). The US Census Bureau has clearly indicated that it does not plan to add these information in the future (the USCB does not need them).
