Consumer-level unmanned aerial vehicles (UAVs) can be purchased off the shelf and be up in the air as soon as the batteries are charged, but the data-driven world of construction surveying often demands something a bit more robust. In anticipation of up- coming regulations from the Federal Aviation Administration, surveying and mapping equipment firms are making big investments in UAVs. Many companies are already offering their own drones that are tailored to the needs of construction surveying.
