UK–Blom Aerofilms Ltd, has signed a NOK 20 million ($ 3 million) contract with Service Hydrographique et Oceanographique de la Marine (SHOM), the French Ministry of Defence body responsible for marine charting, to execute a survey using the Hawkeye LiDAR technology. The project undertakes a detailed aerial survey over an area of some 1,500km in the Indian Ocean. The project will gather, in total, more than 3,000 sq. km. of new data.
The project is due to start in May 2009, and expected project completion is end of third quarter 2010.
The Hawkeye system is a LiDAR instrument for simultaneous bathymetric and topographic surveys. Bathymetric surveys are laser scanning of the coastline, both seabed and land. Hawkeye represents one of the bathymetric technologies available on the market.
In an another development The United Kingdom Environment Agency (EA) has awarded Blom Aerofilms, a framework agreement for a laser scanning project with a value in excess of NOK 10 million ($ 1.5 million). Blom will conduct surface and flood mapping services to identify and evaluate areas at risk from flooding across England and Wales.
Blom is using LiDAR, high resolution aerial laser scanning technology, to gather 3D topographical data, collecting and analysing detailed terrain and surface information, including building heights and shapes. Used to identify drainage patterns and water flow, Blom’s LiDAR is among other a key tool to collect highly accurate height data used to predict which areas and structures are most at risk from surface water flooding in different weather conditions.
