Evaluation of Geostatistics and Wavelets for Identifying Relations Between Imagery and Different Spatial Resolutions and for Data Compression
Abstract
This is the second report of the project to apply geostatistics and wavelet analysis to part of the area chosen at For AP Hill in northeastern Virginia. This report embraces a summary of time spent at Reading by J Shine and by Dr Oliver at TEC, cokriging of Korean temperature data, and the analysis of the vegetation data for the first two of four surveys. The cokriging of temperature in Korea is an exercise to determine whether estimates can be improved by using more information on altitude to estimate temperature with smaller error than by ordinary kriging. A detailed statistical and geostatistical analysis has been carried out on the measured vegetation data for surveys 1 and 2. This included a principal components analysis, summary statistics and histograms, and variogram analysis and modelling. Some of the variables showed similar ranges of spatial dependence to those observed in the pixel information from the SPOT image. The cross variograms between some vegetation measures and image data also suggest that there is a relation in their spatial structures.
