Costs of buying or renting the equipment, maintaining it, and training operators can be high. Time is needed for transport, maintenance, and training. Some kinds of equipment are hazardous to operate. Sensitive ecosystems may be damaged by the equipment. Aircraft, particularly helicopters, are used in some soil surveys to transport workers and equipment and to provide broad views of landscape and vegetation.
Aircraft are useful for photographing landscapes, soil patterns, and land use.
Availability, cost, and lack of conventional landing sites are the main limitations.
