2 I n t r o d u c t i o n o f p r o b l e m User Uptake Almost half of European population lives on coastal areas

3 I n t r o d u c t i o n o f p r o b l e m User Uptake High impact on the natural evolution of coastline Natural erosion of coastline become a problem Impact on houses, economic activities and infrastractures

4 M o n i t o r i n g t h e c h a n g e s User Uptake In order to understand the threats on coastal areas is important to monitor the evolution of urbanization in those areas Use case 1: The Italian Imperviousness layer at 5/10 m spatial resolution for monitoring changes in sensible zones Use case 2: Coastal anthropogenic pressure indicator for urban planner and coastal manager

5 User Uptake USE CASE 1

6 I t a l i a n d o w n s t r e a m a t 5 / 1 0 m User Uptake A very high resolution Imperviousness layer was product for Italy (2012, 2015) Spatial resolution of 5 m for 2012 and 10 m for 2015 (Sentinel-2 data used) Product for Italian National Institute for Environmental Protection and Research

7 T h e I t a l i a n 5 m r e s o l u t i o n i m p e r v i o u s n e s s l a y e r User Uptake With respect to the European scale (20 m), the better spatial resolution data allowed the classification of minor sealed soil elements (including small road and railway network) Rome

8 C o m p a r i s o n H R L a n d 5 m l a y e r User Uptake EEA imperviousness layer 5 m imperviousness layer (the specifications are similar but not the same)

9 A n a l y s i s o f c h a n g e s User Uptake The changes on sensible coastal areas (300 m from coastline in Italy) New impervious areas in sensible zone

22 User Uptake USE CASE 2

23 I n t r o d u c t i o n o f p r o b l e m User Uptake Homogeneous time series of third part input data allow a consistent estimation of the human impacts through the years for an independent evaluation of them

24 I n t r o d u c t i o n o f u s e c a s e User Uptake Aim of indicator To quantify the urbanization on coastal areas It provides a measurement of the impact of the urbanization on coastal areas It provides information useful for urban planner and coastal manager

25 D e s c r i p t i o n User Uptake 3 buffer areas are defined from coastline 300 m 1 km 10 km

26 D e s c r i p t i o n User Uptake To compute the amount of impervious areas in these buffer zones for the entire region and for the administrative units (provinces, regions, counties, etc.)
