The scaled model shape resolution for cutting is 100 DPI or .01" (10000 elevation points per square inch).

Model size is 15" x 10" ... often model size is adjusted after looking at the image and elevation grid in Global Mapper.

Model scale is 1:9600 or 1"=800'. The unscaled model size is 12000' x 10000' (2.27 miles x 1.89 miles).

Unscaled model parameters

Multiplying the above parameters by the scale factor, 9600, and converting them to meters for use for Global Mapper file export.

1) Calculate the XY sample spacing: .01" x 9600=96/39.3700787 meters or 2.438400002 meters

2) Calculate the image sample spacing: .002" x 9600=19.2"=19.2/39.3700787 meters or .487680000 meters

3) Calculate the model size in unscaled space: Width 15" x 9600 Height 10" x 9600 ... Width 3657.6 meters Height 2438.40000 meters

These values are entered into the GeoTIFF Export Options to make the SHAPE and IMAGE files. Here are the Global Mapper steps:

----> resulting shape file AugustaSHAPE1.tif ... 1501 x 1001, 6.0 MB

----> resulting image file AugustaIMAGE1.tif ... 7500 x 5000, 37.8 MB
