A single battery enables the survey of up to 50 acres, but with Site Scan Field it is possible to split a job between multiple batteries to survey larger areas. This feature operates automatically without any input from the user.
When planning a survey, Site Scan Field approximates the number of fully charged batteries the drone will consume to complete the job. Here, I planned a low altitude, 95% overlap, 95% sidelap survey that will consume 10 batteries.
Take off as normal, but note that the Site Scan Field now checks the battery before flying. Here I begin with 83%, so the I am alerted that my battery is not full.
The drone will then fly the prescribed path capturing images along the way.
Upon landing, the drone will prompt for a battery change. Change the battery or end survey if you would not like to capture the remainder of the photos.
When you replace the battery and wait for the drone to reconnect, Site Scan Field will allow you to continue the survey. Note that this behavior occurs whether the survey was ended prematurely by the user or the battery.
After tapping "Continue Survey", simply swipe "Take Off" and the drone will continue autonomously capturing your aerial data.
