Report of the Geostatistical Analysis of High Resolution Multispectral Imagery
Abstract
This is the final report of the project to apply geostatistics to a high resolution remote imagery. The area chosen for analysis is part of Fort A P Hill in north-eastern Virginia. This report includes some of the earlier reports, the aide memoir for geostatistical analysis, and the latest analysis of the 1m resolution imagery. Part of this project has been used to set up some geostatistical computing capability for TEC. Dr Oliver visited TEC for this in 1996. The initial analysis was of a SPOT image. The area chosen for study, to The north of Anderson Camp was divided into a working area and a validation one. A variogram analysis of the SPOT image revealed two scales of spatial variation. Kriging analysis was performed on the three wavebands and NDVI, and the report contains the maps of the area from the analysis. They show clearly that there are at least two spatial scales of variation that we - can identify from the SPOT image The analysis of the ground cover data from three transects show that three distinct spatial scales emerge: about 200m , 500m to 600m, and 1200m, which accord with those from the multivariate variograms. These spatial scales in ground cover match those in the image data closely. The variogram analysis of the high resolution imagery has shown that although more spatial scales have been identified than from the SPOT image they correspond closely and there is little additional information.
