BLOM AWARDED LASER SCANNING PROJECT IN THE NETHERLANDS

Rijkswaterstaat, the executive arm of the national Dutch Ministry of Transport, Public Works and Water Management has awarded the Blom Group a contract for a LiDAR (laser scanning) survey project of approximately NOK 10 million. The project is a part of a 5 year program to improve the Dutch National Height Model.

Rijkswaterstaat has awarded the Blom Group’s subsidiary in UK, Blom Aerofilms Ltd, a contract for a LiDAR survey project. The data acquisition and processing, which is due to start immediately, involves scanning an area of 2,200 square kilometres, covering the province of Flevoland and part of Noord-Holland / Utrecht. Data acquisition will be completed by end of first quarter 2009, and processed data will be delivered to the customer in January 2010.

The dataset will be used for a wide range of purposes such as:
• Water management and planning
• Verification and monitoring dike positions
• Flood risk and environmental impact studies
• Road planning
• Urban planning
• 3D-visualization

To accurately capture the data, Blom will be using their Blom TopEye Mk III technology, a system and processing software developed and operated by Blom Sweden. Blom TopEye Mk III is a helicopter based laser scanning and aerial imaging platform for the capture of high resolution data which is ideally suited to this type of project. The resulting detailed height model will consist of 10 points per m2, with an absolute height accuracy of 5 cm. In addition, high resolution colour images will be taken simultaneously.

This project is a part of a five year program of Rijkswaterstaat to create an improved version of the Dutch National Height Model (AHN-2). The project is now in its second year, and the contract opens up for additional opportunities in the next three years. The creation of the first version of AHN began in 1996 and in 2003 the nationwide height model was ready. AHN had about one point per 16 m2 and a height accuracy of about 20 cm. The height model has been a great success to date. However, users require an updated version, with a more detailed and accurate dataset.

“This is a key project win for the Blom Group, allowing us to demonstrate the accuracy in terrain detail that can be achieved using Blom’s TopEye Mk III technology. We look forward to working with Rijkswaterstaat on what will be an exciting and challenging project,” said Dan Schnurr, Director of Laser Scanning, Blom Aerofilms.
