New Service Announcement! LiDAR

Nowak & Fraus Engineers (NFE) is excited to announce the addition of a new service: Surveying and Mapping using LiDAR. LiDAR, which stands for Light Detection and Ranging, is a method used to determine distances from objects or surfaces by emitting light and then calculating the time it takes for the reflected light to return to the receiver. LiDAR technology has various applications in surveying, archaeology, forestry, and space exploration.

LiDAR sensors in the surveying and mapping field can be aerial-based, UAV-based, terrestrial, or vehicle-mounted. Each setup has its advantages and disadvantages. Many products in the market cater to the user’s specific needs for accuracy, precision, and efficiency in terms of cost and time. NFE has recently acquired the state-of-the-art Trimble MX50 vehicle-mounted sensor with AP60 IMU (Inertial Measurement Unit). Trimble MX50 has the capability of collecting 1.5 million points per second in 3D with vehicular speeds up to 68 miles an hour. The AP60 IMU ensures we can take advantage of the total, high-powered GNSS-inertial processing needed for precise and accurate survey grade point cloud. We have successfully performed large site topographical surveys under heavy tree cover and multiple corridor surveys while achieving horizontal accuracy of up to 0.02’ and vertical accuracy of up to 0.02’.

Since the Geospatial Department received the Mobile LiDAR from Seiler Geospatial, we have successfully scanned 26.5 miles of Right-of-Way corridors.

With the introduction of our new LiDAR service, the Geospatial Department has significantly reduced its turnover time, freeing up traditional survey crews. This enhanced efficiency to meet our clients’ deadlines while maintaining the NFE field standards for accuracy and quality, a win-win situation for all.
