We describe an embedded system for vehicle navigation. We use an Internet-based connection to download data stored on a distant server and a Java-enabled Web browser interface to visualize them locally. Data management is based on vehicle location. All data are transferred as the result of queries defined on the client side and executed on the data server. The request management on client side uses a data cache and takes into account spatial aspect of data and client location. We also introduce spatial query restrictions in order to reduce the selected data only to the data set relevant to the actual location of the mobile user. The vehicle is located by defining several map-matching algorithms to perform in real time integration of vehicle location in digital maps.
