  1. GreenView – Refinement of surface and vegetation parameters in SEE region based on satellite images Environmental VO, SEE-GRID-SCI 09 December 2009 Dorian Gorgan, Danut Mihon, Victor Bacu Technical University of Cluj-Napoca Romania Róbert Mészáros, Györgyi Gelybó Eötvös Loránd University Hungary The SEE-GRID-SCI initiative is co-funded by the European Commission under the FP7 Research Infrastructures contract no. 211338

  2. GreenView Application • Primary contact Dorian Gorgan dorian.gorgan@cs.utcluj.ro Technical University of Cluj-Napoca Romania • Current status • Beta -> production phase • Expected availability • 1st April 2010 • Licensing status • GPL 3 NA4 – User communities support, Environmental VO - GreenView Application 2/28

  3. GreenView Application • GreenView -Refinement of surface and vegetation parameters in SEE region based on satellite images • The aim of the GreenView pilot application is a refinement of surface and vegetation parameters in SEE region based on satellite images. In the frame of this project, construction, usage and comparison of diverse satellite datasets will be performed. • High resolution satellite measurements can be used for numerous environmental studies (climate-related or air pollution modeling). • Using the sophisticated environmental data the change of the vegetation distribution in the Carpathian Basin and its climate-related causes will be investigated. It may also be used to extend the urban climate related research, in order to study the impact of urban environment on the vegetation.

  7. GreenLand component NA4 – User communities support, Environmental VO - GreenView Application 7/28 Goal - Satellite image classification based on different vegetation indices NDVI - used to detect live green plant canopies in multispectral remote sensing data NDVI = (NIR - Red)/(NIR + Red) EVI - used to correct some distortions in the reflected light caused by the particles in the air as well as the ground cover below the vegetation. EVI = 2.5*(NIR - Red)/(NIR+6*Red-7.5*Blue+1) SAVI - accomplishes both good image segmentation and a high performance regarding the differentiation from vegetation and non-vegetation SAVI = (NIR - Red) / (NIR + Red + 0.16) GEMI - used to minimize the atmospheric influence in the classification process GEMI = η*(1-0.25*η)-(Red-0.125) / (1-Red), where η = [2* (NIR – Red)+1.5*NIR + 0.5*Red] / (nir+red+0.5)
