Based in Lake Geneva, Wisconsin, Cardinal Engineering provides high-accuracy drone LiDAR surveying services using the DJI M350 RTK and Zenmuse L2, the latest in drone-based spatial data technology. Paired with Carlson’s BRx7 GNSS base station, we deliver survey-grade precision in real time, reducing time in the field and improving post-processing accuracy.
We work on projects throughout Walworth County, Southeastern Wisconsin, and beyond, from wooded acreage to industrial zones, supporting professionals who demand results they can build on.
