Tasks to complete for Lantea Maps: Required: * Improve tile cache: ** If cached tiles have changed, possibly also try (async) updates of other cached zoom levels covering this area ** Pre-cache tiles in adjacent areas and possibly zoom levels * Improve texture cleaning algorithm * Show a notification when we are loading tiles or saved data * Display length and duration of track * Display movement speed * Display location accuracy * Show a better visible marker for the current location, possibly also indicating movement direction/speed * Smooth animations for zooming, probably using some WebGL magic * Use available larger/smaller tiles with resizing as loading placeholders while zooming in/out * Better GPX saving implementation [blocked by missing web APIs] ** Set file name to save into to a good default (date + maybe some location name) Nice To Have: * Possibility to auto-rotate map to match movement direction * GPS details display (satellite visibility/strength) [blocked by missing web APIs] * Magnetic compass display (using orientiation API) Future Possibilities: * Routing / Turn-by-turn navigation * POI display * Search address * Mark a target location and show distance to it
