Figure 4 — Eldorado test site after simplification by the 
'IBIS' spatial filtering technique. Image was enlarged 3X 
so that subpixel operations could be performed to remove 
diagonal connections (Figure 1). Spatial coherence has 
been improved and polygons meet the 10 acre minimum re 
quirement. Compare with Figures 2 and 3.
