Our Remote Sensing Equipment
Network Mapping constantly explores and invests in the latest remote-sensing instrumentation for data capture operations, to ensure that we remain at the forefront of the survey industry.
LiDAR Equipment
We own and operate various Optech ALTM LiDAR sensors, ranging in pulse‐repetition frequency from 50 kHz to 200 kHz. All our systems are easily installed and calibrated in fixed‐wing aircraft, and have custom‐built mounts for use on helicopter platforms.
Example System: ALTM C200 – This is Optech’s latest innovation in scanner technology; with its 200 kHz sampling capability, we capture more detailed data than ever before.
Imaging Equipment
We deploy a range of photographic sensors that acquire both downward- and forward‐looking imagery. Downward‐looking imagery is orthorectified, to give it the geometric properties of a map.
Example Camera: DiMAC Ultralight – This state-of-the-art camera weighs only 15kg and is capable of taking up to 60-megapixel images. With full frame CCD, a 70mm lens and Forward Motion Compensation (FMC), this powerful camera complements our high-performance laser scanners.
Ground Control
Network Mapping has a dedicated team of highly‐trained and qualified land surveyors, who establish ground base stations and ground truthing sites for every survey operation.
In-flight Weather Data
In addition to the collection of weather data from ground base stations, we also acquire weather data during flight. This is particularly useful for the electricity transmission industry, where determination of the ambient temperature provides an input to thermal calculations.
