Implemented Applications (cont.)

The third that have been implemented in CCUBE involved computations and transformations for Earth scientists, based on spatio-temporal grids of vegetation (NDVI) and sea-surface temperature (SST) indices. The implemented queries (transformations) included NDVI computations over arbitrary areas, computing areas with a given rate of SST change, computing time series of spatial correlations over shifted areas, temporal correlation over spatial areas, and various spatial aggregations, producing input to an animation movie of NDVI change, and computing areas with SST anomalies.

Click here to view or download a movie ( QuickTime format, 650KB ) that shows NDVI changes for a year and a half period. The data for the movie has been produced as a result of a single several-line CCUBE query.
