This web app is mainly targeted at mobile devices and intended for people finding their way around as well as documenting travels. Maps are being displayed in default "Mapnik" OpenStreetMap style by default, but other styles like Cycle Map or Transport Map are available. The second feature is "tracking" of locations, meaning the ability to display your location and record a track of your movements for documentation. This track (most useful if you have a GPS receiver in or connected to your device) can be saved in GPX format. You can use those saved files with many applications to display them and show others where you have been or e.g. edit OpenStreetMap on the basis of that recorded information. Note that Lantea Maps does not send any location data to anyone else, it's recorded locally on your device only. The app name "Lantea" is based on a fictional mostly-ocean planet in the "Stargate: Atlantis" TV series, on which the Ancients erected the artificial "island" city of Atlantis. This app is listed in the Mozilla Marketplace at https://marketplace.mozilla.org/app/lantea-maps/ and is running on http://lantea.kairo.at/ The main repo is http://git-public.kairo.at/?p=lantea.git;a=summary but it's listed on GitHub at https://github.com/KaiRo-at/lantea for convenience for potential contributors. See the TODO for tasks that you can help with. Please don't use GitHub for issue tracking but http://bugzilla.kairo.at/
