The telecom market is a dynamic and fast evolving market. To maintain or improve their position telecom companies have to optimize their wireless network and reduce their costs. In the Netherlands EUROSENSE created a countrywide database consisting of polygondata of buildings, industry, vegetation, water and greenhouses. Each of these classes has its own characteristics in relation to propagation of radio waves. From this polygondataset three clutterdatasets were derived, one expressing the occurrence of classes, one showing the density of buildings and vegetation and a third one expressing height of buildings and vegetation. These three clutterdatasets are used to produce radio propagation models. Telecom companies use these models to calculate the quality of a signal at a certain place. These results can be used to optimize networks and to define the placement of new radio masts.
The polygondata, although an intermediate product for telecom companies, appears to be very useful for a lot of other applications too. The dataset is being used for flood risk estimations, environmental impact studies, calculation of green- and building areas in cities and visualization of new building projects in urban areas.
In 2009 EUROSENSE created a second update of the polygon- and clutterdata based upon the DKLN 2008 (Digital color aerial imagery of the Netherlands). This update is now available. Earlier versions from 2003 and 2006 are still available, as well as the intermediate database with all changes between 2003 and 2006 and between 2006 en 2008. Click here to order data.
Below examples of the three types of clutterdata: based on classes (left), based on density of buildings and vegetation (middle) and based on height of buildings and vegetation (right).
