The whole of Belgium on a scale of 1 : 10,000
An important task of the NGI (National Geographic Institute) is to digitally map the whole of Belgium on a scale of 1:10,000. This is a particularly interesting scale as it provides an overview of the whole territory while showing enough details at the same time. However, when dealing with large scale surveys, the question of updating becomes very important. At this level, the reality on the ground is constantly changing, especially the built-up areas and the road network, and to effectively meet the demand for geographical information from potential users this information must be updated regularly.
