The contract is one of two Lots awarded under AHN2 Contract DI-5524 and involves BKS acquiring and processing low level LiDAR data of an area covering approximately 365,000 hectares. For the data acquisition, BKS will use Fugro’s FLI-MAP 400 helicopter mounted LiDAR system that combines an ultra-high frequency (150KHz) LiDAR with forward and nadir facing digital cameras and videos to capture high density (10pts per m2) point cloud data and associated imagery to survey flood defence assets.
Acquisition of the data began mid-January and will be completed by March. The raw collected data will then be filtered to produce a 50cm grid height model of the area with the entire project due for completion by November 2008.
BKS have considerable experience in the execution of LiDAR data collection and are the UK and Ireland agents for the FLI-MAP system of Fugro, employing it on various contracts including National LiDAR Framework agreement for the UK Highways Agency and the survey of river embankments for various regions of the Environment Agency.
