Unmanned Aircraft Systems

Unmanned Aircraft Systems (UAS) provide the most comprehensive view of field conditions as possible. DLZ has the tools and expertise to accurately capture real world conditions and bring them to your desktop. The use of UAS technology allows DLZ to acquire data without the need for field personnel to get physically near surveyed objects. This promotes safety and efficiency in the field, especially in conditions that would be harmful to our employees.

With several FAA certified licensed Remote Pilots, DLZ understands Federal regulations, airspace restrictions and procedures. We have invested in the latest UAV Unmanned Aerial Vehicle technology includes both copter and fixed wing options allowing for multiple surveying and inspection applications at various precision.
