Specify the Site Bounds
Select a model scale. In Google earth, draw a box around the model site. Minimize the model size to reduce cost. Use the Google Earth zoom and distance scale to view and verify model image feature size.
Email the site KMZ file for cost. Please include a contact name and phone number.
Note: USGS imagery may be different than Google Earth and model bounds may be slightly different due to map projection of Google Earth versus the map projection used for the model model.
Example: Louisville, KY ... 1"= 1000' scale
In Google Earth draw a box around the site. Model length is 38.2" Model width is 18.7"

We generate the GeoTiff SHAPE and IMAGE files (below) to make the model from USGS data. You review and approve before making the model.

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.
