In the report a procedure for characterizing vegetation of inaccessible areas for input to munition height-of-burst models was developed. The procedure entails three steps: statistical stratification, vegetation sampling, and vegetation data transformation. An area is stratified on the basis of average height, crown diameter, and spacing of plants in the upper two layers using the WES factor mapping process. For each unique combination of factors mapped, a 20-plant minimum sample is taken for each height layer. Sample data include average spacing of plants and the height and crown diameter of each plant. Data are obtained photogrammetrically when feasible; otherwise, available ground-truth data are substituted. Plants with known stem and branch geometries are then substituted for the sample plants.
