- Define “intervisibility”
- Outline an algorithm to determine the viewshed (area visible) from specific locations on surfaces specified by DEMs
- Perform siting analyses using specified visibility, slope, and other surface related constraints
- Explain the sources and impact of errors that affect intervisibility analyses
