The elevation information of a whole country in a resolution of one to several measurements per metre with accuracy better than 10 centimetres? Only a few years ago this seemed to be unrealistic, both technically and commercially. However, this changed with the arrival of airborne laser scanning technology. The Netherlands were an early adaptor of this technology and began a project in 1996 to scan the entire country using airborne laser scanning. The result, four years later, was a nationwide elevation model with a point density of 1 point per 16m2 and an absolute accuracy better than 15 cm!
Several other countries followed this example, including: Belgium (Flanders), Switzerland and the German federal states (the so-called Bundeslaender) Baden-Wuertemberg, Bavaria and Schleswig-Holstein.
More and more countries continue to discover the benefits and economical advantages of such uniform accurate data sets and define them as part of their Geospatial Data Infrastructure (GSDI). The cost-effective data sets support water managers, foresters, land-use planners, city planners, environmentalists, archaeologists and many others with basic data to enhance performance in their daily work.
In most cases the realisation of the data sets is financed by a number of governmental organizations via a co-operative effort.
TerraImaging can assist in more than just the technical realisation of these data sets by laser scanning. Our consultants can also advise you about the technical and contractual aspects. We will use our experience to assist you with the financial and organisational elements and help you to develop realistic business models for the realisation and exploitation of these data sets.
