OpenStreetMap is an online map that uses an open geographic database, updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and is commonly used to make electronic maps, inform turn-by-turn navigation, and assist in humanitarian aid and data visualisation. OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine, and editor.

Turn-by-turn navigation is a feature of some satellite navigation devices where directions for a selected route are continually presented to the user in the form of spoken or visual instructions. The system keeps the user up-to-date about the best route to the destination, and is often updated according to changing factors such as traffic and road conditions. Turn-by-turn systems typically use an electronic voice to inform the user whether to turn left or right, the street name, and the distance to the next turn.

However, in many cases, it is also that which makes the program free, avoid the need of an Internet connection, and make it very lightweight. Very basic programs like this may not be suitable for road navigation in cars, but serve their purpose for navigation while walking or trekking, and for use at sea. To determine the GPS coordinates of a destination, one can use sites such as GPScoordinates.eu and GPS visualizer.
