1. A method for determining a route for a map surveyed, comprising:
receiving, by a controller of a vehicle, an initial survey plan, wherein the initial survey plan includes a plurality of initial waypoints, and the vehicle includes a plurality of sensors;
commanding the vehicle to move to surveyed a terrain by following the initial survey plan;
surveying the terrain with the plurality of sensors as the vehicle moves according to the initial survey plan to develop a map a of the terrain, wherein the map of the terrain includes a plurality of map areas;
determining a confidence level of each of the plurality of map areas surveyed with the plurality of sensors of the vehicle to determine a real-time confidence data;
predicting a confidence level of each of the plurality of map areas yet to be surveyed according to the initial survey plan to determine a predicted confidence data;
merging the predicted confidence data with the real-time confidence data to determine a confidence penalty;
determining whether the confidence penalty is greater than a predetermined threshold;
in response to determining that the confidence penalty is greater than the predetermined threshold, adapting the initial survey plan to produce an updated survey plan;
commanding the vehicle to move according to the updated survey plan.
