1 PROTECTED AREAS from SPACE. Viewing products with data quality and geospatial user feedback Joan Masó

2 ECOPotential description ECOPOTENTIAL is a large European funded H2020 project that focuses on serving Protected Areas; blending Earth Observations from remote sensing and in situ measurements, data analysis and modeling of current and future ecosystem conditions and services. ECOPOTENTIAL considers cross scale geosphere biosphere interactions at regional to continental scales, addressing longterm and large scale environmental and ecological challenges. ECOPOTENTIAL focuses its activities and pilot actions on a targeted set of internationally recognized Protected Areas in Europe Protected Areas include mountain, arid, coastal and marine ecosystems

4 Remote sensing in ECOPotential The multispectral and multitemporal nature of the data allows deriving EO data products that are the essential variables needed for characterizing the ecosystem and biodiversity Products Leaf area index Tree cover density Biomass Surface Soil Moisture Nutrients NDVI, EVI Spectral Soil Quality Vegetation Index composition Fragmentation Surface Albedo Vegetation classification Disturbances Land Surface Temperature Habitats Gross Primary Sea Production Surface Temperature Water turbidity Vegetation wetness Digital Elevation Hydroperiod Model Vegetation height Bare Ground Snow cover Phenology Slope...

26 Where is the secret?

27 An uncommon WMS. In a common WMS, data is rendered in the server and transferred to the client as an image Nice? In ECOPotential we transfer arrays of numbers: coverages. The client generates an image on the flight Let s do something!

28 Why we have not done this before? We are using several HTML5 improvements: AJAX with binary transmission Binary data processed by JavaScript directly Canvas manipulating an image pixel by pixel Faster and faster JavaScript implementations
