Network Mapping has the technical knowledge and equipment required to carry out helicopter-mounted LiDAR surveys. This allows us to fly lower and slower than a fixed-wing aircraft, capturing extremely accurate and high resolution LiDAR and imagery to produce market-leading products. 

Speed

Although flying LiDAR with a fixed wing is faster, in reality a helicopter platform is still an extremely rapid method of data capture and much more efficient than traditional survey techniques. The biggest benefit over a fixed wing platform however is a helicopters ability to fly at low altitude over a survey site. This results in data with a much higher resolution and accuracy.

High Resolution

LiDAR mounted on a helicopter platform will capture an incredibly dense data set. During a LiDAR survey millions of infrared laser pulses are emitted for every kilometre flown, in some capturing in excess of 40 points per square metre. This set up is exceptionally suited to high-level engineering requirements as even the most subtle of changes in terrain are recorded.

Accuracy

We can provide extremely accurate datasets for corridor routes suitable for use in engineering applications. For every project, the accuracy of the survey measurements produced from the aerial LiDAR system is checked, reported and signed-off to clients by our professionally licensed land surveyors.

Linear Assets

Another advantage of helicopter platforms is their ability to track complex linear assets through higher levels of maneuverability than fixed-wing aircraft. This allows us to lower the positioning time for the airframe and to capture the survey dataset as efficiently as possible.

Canopy Penetration

The laser beams penetrate spaces in the tree canopy, providing information on both the ground surface and any buildings or large objects. This means that we can produce models and maps of the ground even when they are masked by forest.

Cost

In most cases aerial LiDAR will present large cost savings when compared to traditional survey methods. Please contact Network Mapping to obtain an indicative price for a survey tailored to your requirements.

Non-invasive

Airborne LiDAR enables surveys to be carried out in difficult and vast terrain, where ground survey is simply not feasible. Network Mapping's staff are experts in mobilising in inhospitable environments with experience working throughout Europe, the Middle East, Australasia and the Americas. This work has included the survey of around 800 km2 in the Ecuadorian rainforest and over the icecaps of Greenland.
