This is the first report of the project to apply geostatistics to high resolution remote imagery. The area chosen for analysis is part of Fort A. P. Hill in north-eastern Virginia. It is on the coastal plain which is heavily dissected in this area giving rise to considerable variation in relief. This report is brief as it has since been decided that the area that we started to analyse will no longer be used. This is for practical reasons. The variograms for this area showed two distinct scales of spatial variation that could be identified in the field. We shall now analyse the data for a much larger single area that we can divide into a working area and a validation one. This will enable us to test the ability of the methodology to predict ground conditions from imagery alone, and to design sampling schemes. At present we have SPOT imagery, but this will be accompanied later in the year by a high resolution imagery recorded for three seasons. The SPOT data for the area is now available and we shall start the variogram and kriging analysis of these shortly. Part of this project has been used to set up some geostatistical computing capability for TEC. Dr Oliver visited TEC for this and the report on this visit is appended to the main report.
