![]() We spent the day with the survey team in one of the latest techno survey cars and learnt how the maps are created and updated. Things have changed quite a bit in the three years since so we went back to the new Watford office to see how the technology has improved. Way back in 2004 we visited Navteq at their Boreham Wood office in the UK to see how they created maps ( click here for the article). But of the free software available, it provides one of the best methods for backing up map data and using it in different contexts.The making of Navteq Maps: Onboard with the survey team That's not strictly what it was made for, though: MapSphere was developed as a way of sharing 'tracks' – GPS trails around areas – and sending real-time GPS data to the web. MapSphere is a great way to use Yahoo Maps, OSM and, using an extension, Google Maps – with GPS support on any machine. This is available from to download from here. You'll need to have the free tool SendMap too. The same command with the parameter -upload transfers a converted map to a connected device. GroundTruth is a command-line application that converts OSM files.Įntering the command groundtruth makemap (with appropriate parameters) creates Garmin readable maps from OSM XML sources. You'll need to export your map in OSM format, then convert that XML data into a Garmin-supported MP file. ![]() There's a more comprehensive guide at the OpenStreetMap Wiki, which features a list of supported units. The OpenStreetMap format can be converted for use with most Garmin GPS devices. You can also create your own standalone embedded HTML maps for inclusion on websites. The export dialog enables you to output maps in OSM's own XML format, as Mapnik bitmap images tiles or as an Osmarender SVG format image (a vector file). ![]()
