Survey drones may be fixed-wing, single-rotor (helicopter) or multirotor, with each platform having its own advantages and disadvantages.
Multirotor systems are able to hover in place, providing greater manoeuvrability, and have VTOL (Vertical Takeoff and Landing) capabilities. They are usually limited to battery power, which means that they have short flight times and ranges, although it is possible to equip some systems with hydrogen fuel cells that boost endurance.
Helicopter UAVs share the hovering and VTOL advantages of multirotor drones and are typically powered by combustion engines, giving them longer flight times. They are however more complex systems that require more maintenance.

Fixed-wing drones usually have a longer flight endurance than multirotor systems, and so can perform larger surveys in a single flight and carry heavier payloads. However, they require a runway in order to take off and land, and may also need specialised launching equipment.
Hybrid VTOL fixed-wing drones combine the VTOL capabilities of multirotor drones with the longer flight endurance of fixed-wing UAVs.
