TerraImaging, the youngest member of the Geokosmos Group of Companies, has signed a contract with the Dutch Ministry Rijkswaterstaat for the second part of the Dutch LiDAR elevation mapping initiative AHN2 (Actueel Hoogtebestand Nederland). TerraImaging is proud to announce that they won the biggest part of the three lots, the northern region Groningen/Drenthe. Every company was limited to one lot. The aim of the project is the creation of a highly accurate Elevation Model for the whole country. The Dutch Ministry was one of the first to detect the benefits of LiDAR technology. TerraImaging has already been involved in the creation of the first nationwide Elevation Model of the Netherlands in the 1990s (AHN).

An up-to-date and highly accurate nationwide Digital Elevation Model is essential for the Netherlands – a big part of its territory is under sea level, TerraImaging will help Rijkswaterstaat to fulfill their task to provide dry feet, clean and sufficient water and a quick and safe flow of traffic.

The second phase of the national Dutch LiDAR elevation mapping initiative is aimed at revising and updating geospatial data every five years. The customer of the project is Rijkswaterstaat, founded in 1798 as the Bureau voor den Waterstaat, is part of the Dutch Ministry of Transportation and Water Management. The main areas of the agency are construction and maintenance of waterways and roads.

In 2007 Rijkswaterstaat initiated the first phase of AHN2. Now the project approached the second stage and TerraImaging won the biggest lot. The project time span is from February 2009 until February 2010. TerraImaging’s professionals will perform LiDAR survey of the area which equals to 357 000 ha, a digital camera will simultaneously acquire image data.

The requirements are advanced and challenging – the point density is defined with 8 laser points per 1 m², an accuracy of 5 cm will be delivered. Additionally digital geo-referenced images with a resolution of 7 cm will be a deliverable. The LiDAR data will be classified using TerraImaging processing procedures.

Quality is a very important issue in this project; TerraImaging has adapted its strict Quality Scheme to the requirements of this project and will ensure the quality with redundant checking and control procedures.

Jan Willem van der Vegt, Director of TerraImaging states in this respect: “We are very proud to be a part of the national project and make a contribution to the development of our country. The data provided by our company will form the basis for geoeconomic planning and modeling of the whole territory of the Netherlands. The output products will serve as an effective tool for flood and natural resources monitoring and will help effectively solve a lot of vital tasks.”
