Application of Geostatistical Methods and Wavelets to the Analysis of Hyperspectral Imagery and the Testing of a Moving Variogram
Abstract
This is a first report of the project. It incorporates the report on an analysis completed in the previous project on moving averages, variances and variograms for NIR from a SPOT image of part of Fort A. P. Hill. In addition the computer programs for these are included. The maps of the variances and the diagram of the variograms show areas of the image that are not stationary and where kriging is likely to perform less well in prediction than wavelet analysis. The second part of the reports summarizes Dr. Oliver's visit to the Topographic Engineering Center in June 2000. The third section comprises work on a part of the image analyzed previously, called aphillcut' to distinguish it from the larger section of image used. This work has explored in detail any relation between elevation from a digital elevation model, the raw elevation data and NIR and NDVI. The correlations are weak in spite of the visual relation. The strongest relation was between the moving averages for NDVI and elevation for a window of 10 x 10 pixels. The final section describes the initial work that has been done on the hyperspectral hymap' data. This is principally a correlation analysis and principal component analysis.
