The first step was to establish the 1:1400 scale of the model which turned out to be too high a
resolution for available DEM data. To solve the problem, 4274 traced USGS topographic maps in AutoCAD and
interpolated terrain topography to increase the resolution. Kennedy Fabrications was then able to create the
3-D cutting model shown here. The model has no vertical exaggeration and spans a real height variation of
almost 700 feet in a 4200' x 2800' area.
