We generate the GeoTiff SHAPE and IMAGE files (below) to make the model from USGS data. You review and approve before making the model.
SHAPE 3901 x 1901 100 points per inch IMAGE 19500 x 9500 500 pixels per inch IMAGE and SHAPE combined to verify alignment
The model size was increased from 18.7" x 38.2" to 19" x 39" for one inch size increments. USGS 1 meter orthoimagery was used for the IMAGE. USGS 3 meter and 10 meter elevation data were used for the SHAPE. A UTM projection was used.
The site has 271' of relief (high 650' - low 379') or .271" model relief. Vertical exaggeration of 2 or 3 would increase model relief.
