MOBILE LIDAR MAPPING
Mobile LiDAR mapping is Flight Evolved’s solution for collecting large amounts of survey grade LiDAR data. Mobile LiDAR mapping offers the same level of high definition resolution and global accuracy as our UAV units, but now on a mobile platform. This allows us to cover large areas in a very short amount of time. Mobile scanning can cover hundreds of miles in a day going at normal posted speed limits. This is possible due to our high density scan rate (700,000 points/sec) and number of lasers (32).
Relative accuracies can be as low as 2cm, with global accuracies around 5cm or less. Flight Evolved is able to achieve these low accuracies by post processing the GPS and IMU data with the raw point data to calculate a trajectory of the route. The trajectory is processed alongside our onboard GNSS and ground base station data to produce a globally accurate point cloud. These types of global accuracies used to be thought of as impossible, and now part of our standard procedure.

Acquisition Efficiency: Hundreds of Miles Per Day
Mobile LiDAR mapping creates a unique opportunity for LiDAR data acquisition. Our small sensor can be mounted nearly anywhere. This can be a vehicle, boat, ATV, or even a backpack. This kind of mobility offers endless possibilities. We are able to analyze a project and pick the best “vehicle” for acquisition. For larger, hard to access areas, a UAV makes the most sense. However, mapping shorelines on lakes, rivers, or the ocean are perfect opportunities for a boat mount. For city and road work, our vehicle mounted LiDAR sensor is the perfect tool for the job. This flexibility allows us to get the best possible data by the most efficient means possible. This helps keep our prices low and maintain a high quality product.
