Trend Surface of Biophysical Factors

Digital Elevation Model and Point Data

The elevation, slope, average temperature and precipitation surfaces are shown on the map. The slope map was derived from digital elevation model. The temperature and precipitation surfaces were interpolated using values from point data.

Upper left-hand map displays elevation in meters, upper right-hand map shows slope percentage. Lower left-hand map shows temperature Fahrenheit and lower right-hand map shows precipitation in inches
