Take off on uneven surface

while connecting powering drone on an uneven surface the ground is considered at an angle with respect to uneven surface is there any way this can be resolved with help of mission planner for ground

What vehicle? is it a multirotor or a plane? What firmware version? What Mission Planner version?

If the ground is uneven the mission planner will display it as uneven. There is no fix for that.
