What We Offer
UAV LiDAR Services
This means for things like power line inspections, vegetation studies, and large mapping jobs, UAVs simply cannot be beat.
The sensor that Flight Evolved operates will outperform nearly all manned aircraft versions. We are capable of multiple-returns with online waveform processing, generating 750,000 points per second. We have state of the art fiber optic IMU and GNSS systems that allow us to achieve relative accuracies of 15 mm.
Our accuracy is a result of new technology and processing techniques, but also because of our acquisition altitude. Our flights are conducted at altitudes of a couple hundred feet or less. Less altitude = better accuracy because there is a lower degree of error. By default, all aerial platforms will exhibit a certain level of heading, roll, and pitch error. However, this error has a greater magnitude at higher altitude.
For example, think of an archer shooting a bow and arrow. If he is shooting at a target at 10 meters away, and is 0.1 deg off, he will miss the target by 1.75cm. Now take that same 0.1 degree error, and put the archer back at 100 meters and he will miss the shot by 17.5 cm. This example translates to data acquisition heights. Any inertial or trajectory errors are much more exaggerated at higher altitudes. So everything being equal, lower altitude = higher accuracy. Traditionally, this is why helicopters are required for projects that demanded greater accuracies.
Also, Flight Evolved’s LiDAR sensor produces a staggering 750,000 points per second. High scan rates and high relative accuracies mean there is less interpolation. Less interpolation = more accuracy. This setup is capable of 7 returns, which allow for vegetation penetration, tree height measurements, and accurate data gathering.
The software outputs to common LAS and LAZ (compressed) point cloud file formats. Import these point clouds into PLS-CADD, AutoCAD, ArcGIS, or your favorite GIS/CAD software. .BAK backup files are created that correlate the laser classifications to a PLS-CADD project. All pertinent info, such as weather, oblique images, ortho imagery, and laser data are all bundled in this type of deliverable.
UAV LiDAR Comparison
- Typical UAV LiDAR costs depend on the data that is needed. However, conventional aircraft require pilots, fuel, airports, fuel trucks, hangar fees, and a multitude of other things before they can even take off.
Generally speaking, even small LiDAR mapping jobs can cost upward of $20,000 – $50,000 for a plane or helicopter operation. And in most cases, that is a fair price considering the logistics required.
Unless the project site just so happens to be right beside the departure airport, it is usually a decent commute for the aircraft. If this is over a couple hours of flight time, a fuel stop will be required.
- The hope would be that the project is small enough that they can use the fuel on board to complete the mission. If not, they will probably need to bring a fuel truck and fuel driver as well.
This example of complexity and logistics goes on and on. The project site in this case was small and simple, not to mention anything that would require multiple flying days. Needless to say, there is a major ease-of-use factor that is favored heavily by UAVs. Not to mention the costs of that whole helicopter operation.
