Aerial laser survey (LiDAR) for the rapid production of highly resolved and accurate topographical surveys

We are specialists in the use of both rotary and fixed-wing platforms for LiDAR surveys. Our technology allows us to rapidly produce highly accurate cartographic and engineering products that usually present cost savings over traditional survey methods.

The laser beams are between 10 - 20 cm (4 – 8 inches) in diameter once they reach ground level. Any portion of this beam area that strikes an object will trigger a reflection that will be measured by the scanner in terms of its geodetic position (its exact X, Y and Z co-ordinates). This position is calculated from an onboard kinematic Global Positioning System (GPS) and ground based differential GPS stations that constantly receive information from a constellation of satellites.

What's more, the scanner is also synchronized to an airborne digital camera that will determine the colour of the object from which the reflection came.

Network Mapping is able to produce a range of products using aerial LiDAR technology. Industry specific product offerings can be found in the industry applications section. For generic aerial LiDAR products, click here.
