Optimize your project developments with innovative surveying technology from our team. When you rely on our meticulous engineers, you put smart and proficient professionals on your side. CDDI's survey crews are trained in the latest equipment. They use cutting-edge equipment from Leica, Topcon, Optech, and TDS on projects, as well as attend regular classes and seminars to stay current. Our advnaced equipment includes:

3D Laser Scanners (Terrestrial Lidar) | Robotic Total Stations | Global Positioning Systems | Digital Leveling

Robotic Total Stations
Robotic Total Stations are state-of-the-art instruments that eliminate the need for an assistant staff member to hold the reflector prism over the point to be measured. Instead, the operator holds the reflector him/herself and controls the total station instrument from the observed point. This translates to lower costs for you. 

Welcome to the future of surveying. LIDAR is capable of acquiring 500,000 points in one minute. It has a vast field of applications and can sometimes be useful where conventional survey equipment is not.
