CNA is applying new geospatial technologies to an ancient science. By maintaining state-of-the-art equipment and utilizing GPS, 3D laser scanners, robotic instruments and drone aerial mapping whenever practicable, we seek to increase accuracy and productivity by streamlining our processes and leveraging emerging technologies. CNA is one of the few companies in California to operate its own high precision grade GPS base station, which is extremely efficient and reliable. Our professional surveyors have hundreds of years of combined experience with complex site surveys, topographic mapping, GPS, bathymetric surveys, construction survey monitoring and numerous other surveying services. CNA is able to provide aerial mapping and remote sensing from acquired aerial imagery, airborne LIDAR and GPS technologies, as well as aerial photogrammetric mapping, geospatial data processing, geometric processing, 3D laser scanning and point cloud mapping. We strive to stay at the forefront of these ever-changing technologies.
