Open Source Swift GIS Software

kmap builds free, detailed maps for any Garmin device (handheld, watch or bike computer) from OpenStreetMap data, on your own computer. Pick a country, a region or a whole continent, press Build, and copy one .img file to the device. The map carries contour lines at the interval you choose, shaded relief and an elevation profile, turn-by-turn routing, address search, day and night colours, and points of interest. Every feature is optional: leave out what your device does not need, and the map gets smaller and faster. Two styles are built in, modelled on Openstreetmap and OpenTopoMap, and kmap can reuse the look of a map you own where its licence allows. Profiles keep a separate set of build settings for each device. kmap runs as a full-screen terminal interface, and every feature is also available from the command line. Map data comes from Geofabrik's OpenStreetMap extracts, updated daily; the tools kmap needs are downloaded on first run.
