GreenView ApplicationGreenView - 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.

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)

*The SEE-GRID-SCI initiative is co-funded by the European Commission under the FP7 Research Infrastructures contract no. 211338

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

*The SEE-GRID-SCI initiative is co-funded by the European Commission under the FP7 Research Infrastructures contract no. 211338

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.

GreenView - Algorithm implementation We will need three operators in our example application: system coordinate conversion, interpolation algorithm computation, and the pseudo-coloring.
