The latest update for iOS just made my day. Since I live in a mountain area this makes it so easy to set elevation. Terrain elevation is crucial for planning and flying in mountain area, especially autonomous waypoint flights. It helps judging elevation of mountain or valley without guesswork for waypoint mission planning. Terrain elevation is fully integrated in Mission Planner without requiring Google Earth nor other apps/tools. When "Show Elevation" option is enabled in Settings menu and with internet connection, Mission Planner would retrieve elevation data from multiple DEM (Digital Elevation Model) sources automatically. Additional Home Elevation, Waypoint Elevation, Target (POI) Elevation and AFE (Above Field Elevation) values are shown on the map. When you save a mission, elevation of all waypoints, targets and panoramas are also saved in mission file accordingly for offline use.
