For topographic survey equipment must meet the following requirements:

-The battery of the quadcopter should allow a long flight without recharging. Of course, it all depends on the amount of work and the size of the territory. Still, it’s better that the copter can shoot, if not all, then at least most of it, than you will recharge it many times in one shooting.
- The camera must provide the proper level of image quality. Is it a tree or a house? River or road? Too low quality photos will negate all the work of the operator.
- The quadcopter must be able to climb to the required height for shooting. This requires sufficient signal strength, so models that meet these requirements or tuned copters are used.

There are also special geodetic quadrocopters that optimize the work "in the fields". Equipment for shooting is selected depending on the specific order, taking into account:

the size of the territory;
final materials to be obtained;
terrain type;
weather conditions;
time required for aerial photography.

In addition to direct video recording and pictures, you can get:
