  1. GreenView – Refinement of surface and vegetation parameters in SEE region based on satellite images Environmental VO, SEE-GRID-SCI 10 September 2009 Dorian Gorgan, Danut Mihon, Victor Bacu Technical University of Cluj-Napoca Romania 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 UTCN,third party SEE-GRID-SCI partner acronym Romania • Current status • Beta • 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. GreenView Application • Data interpolation • Computes data to an arbitrarily chosen grid defined by the user • from fine to coarse grid • from coarse to fine grid • Provides data series for a period chosen by the user, in time steps of the original data or averaged for a certain period • Model calibration • GPP (Gross Primary Production) the total amount of carbon taken up by vegetation via photosynthesis • Determination of GPP • Field measurements (eddy covariance technique) – accurate, but limited • MOD 17 product (algorithm is based on the BIOME-BGC ecosystem model) • Calibration and sensitivity analysis – based on BIOME BGC model • Period: 1997–2008, Monte Carlo method • Post processing • Nonlinear inversion method NA4 – User communities support, Environmental VO - GreenView Application 7/28

  8. GreenView – Application Development Methodology 1. Algorithm identification and analysis 2. Data model definition 3. Identify atomic parts of the algorithms • Parallel or serial processing • Implementation as services, procedures, separate applications 4. Algorithm implementation 5. Description of processing using gProcess • PDG Definition • iPDG specification • Execution 6. Create the application interface • Link the application interface to the GRID level NA4 – User communities support, Environmental VO - GreenView Application 8/28

  9. GreenView - Algorithm identification and analysis • Interpolation: eg. neighbor interpolation, bicubic interpolation, bilinear interpolation etc. • Solution: Coarse to fine interpolation • The missing points will be computed using a distance weighted nonlinear interpolation that computes the value of a Vm point from four surrounding known values: V1, V2, V3 and V4. Vi - one of the four surrounding pixels, Vi( ); di - the great circle distance between two points; dmax - the great circle distance between the furthest two pixels of the surrounding four pixels; R - average radius for a spherical approximation of the Earth (≈6371.01Km) NA4 – User communities support, Environmental VO - GreenView Application 9/28

  10. GreenView - Data model definition • Identify the inputs, e.g. satellite image types (MODIS, Landsat, Aster etc.) • The data model will be defined by a MODIS satellite image representing a certain area of the Earth and temperature data values recorded in specific points inside the same area. • The resolution of the MODIS image is 1Km2 and the resolution of the temperature measurements is about 150Km2 NA4 – User communities support, Environmental VO - GreenView Application 10/28

  11. GreenView - Identify atomic parts of the computation • The parts of the processing algorithms that can be executed independently, named atomic parts, should be identified and analyzed for potential parallel execution. • The interpolation algorithm used in our example is a simple one and does not involve separate processing steps, so it can be all considered as an atomic part.

  12. GreenView - Algorithm implementation • We will need three operators in our example application: system coordinate conversion, interpolation algorithm computation, and the pseudo-coloring. NA4 – User communities support, Environmental VO - GreenView Application 12/28
