analysis

Beyond basemap applications, aerial imagery is a powerful source of information for GIS applications.
Together with new 3D visualisation systems, it enables increasingly more elaborate uses for GIS analyses for which Aerodata offers several services.

GIS analysis has many applications. For example the effects of high water levels can be analysed by using laser data and sound propagation studies based on 3D city models.

change detection

Comparison of imagery from repeated survey missions can be a useful source of information, provided that they can be carried out each time under similar conditions.

It is here that Aerodata offers a cost-effective service that is based on a set of criteria of the changes to be monitored. Examples are:

tracking recently installed solar collectors, house extensions, roofs and dormer windows
tree felling
the dumping of construction waste.

The analysis of imagery can be even more effective by using height models of the areas obtained by automatic image correlation or from laser scanning.
