Being able to define a large area you want to map, set the maximum flight time of the airframe, and have survey grid automatically break up the area into different flight segments with X overlap between flights. This would make planning large area's much simpler and you could simply save each flight as a different waypoint file. When you finish the first flight, land, change batteries, load the second waypoint file, and fly again. No guess work on exactly where you left off or how much overlap you need between projects.\r\n\r\n2. Use terrain data to show what the minimum overlap would be. We had this issue recently when mapping very mountainous terrain. All the estimations for overlap and side-lap are based on the altitude of the home beacon, however, if mapping a mountainous area, the overlap and side lap at higher elevations than where the survey grid made the estimations will be considerably less and can effect the quality of the orthomosaic. If there could be a \"Minimum overlap\" indicator based on the elevation of the area you are mapping, it could help set the proper parameters. Or, even more complex, have it change the overlap timing based on the terrain? Side lap would be difficult to adjust, but, overlap could be simple."},"comment":{"url":"https://api.github.com/repos/diydrones/MissionPlanner/issues/comments/141842421","html_url":"https://github.com/diydrones/MissionPlanner/issues/1010#issuecomment-141842421","issue_url":"https://api.github.com/repos/diydrones/MissionPlanner/issues/1010","id":141842421,"user":{"login":"Jman841","id":11892012,"avatar_url":"https://avatars.githubusercontent.com/u/11892012?v=3","gravatar_id":"","url":"https://api.github.com/users/Jman841","html_url":"https://github.com/Jman841","followers_url":"https://api.github.com/users/Jman841/followers","following_url":"https://api.github.com/users/Jman841/following{/other_user}","gists_url":"https://api.github.com/users/Jman841/gists{/gist_id}","starred_url":"https://api.github.com/users/Jman841/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Jman841/subscriptions","organizations_url":"https://api.github.com/users/Jman841/orgs","repos_url":"https://api.github.com/users/Jman841/repos","events_url":"https://api.github.com/users/Jman841/events{/privacy}","received_events_url":"https://api.github.com/users/Jman841/received_events","type":"User","site_admin":false},"created_at":"2015-09-20T22:46:10Z","updated_at":"2015-09-20T22:46:10Z","body":"Very interesting. Is there a way we could \"pause\" the mission other than a low battery trigger? I personally don't like flying to the low battery alarm on purpose. Any way to initiate it manually?"}}
