The aim of the project was to give the 10 participating NMAs understanding in the business case of 3D data: in what applications does a 3D approach give added value?; what are the required 3D data for these applications; and, what are the costs and benefits to collect and maintain these 3D data nationwide?

Six use cases were selected for a value chain analysis. These analyses have been carried out with the main stakeholders in a workshop organised for each of them. The six selected use cases are:

a.         Better Forestry Management, Finland

b.         Urban Planning, Ireland

c.         Asset Management, UK

d.         Flood Management, France & Switzerland

e.         Security and Safety, Belgium

f.         3D Cadastre/ 3D Valuation, Netherlands

In a follow-up step, two of these use cases were selected for further study, i.e. to quantify the benefits and costs for the 3D geoinformation value chain. The selected use cases are “Flood Management” and “Urban Planning”.
