Visual
Exposure Application Examples — two references containing annotated
examples using visual analysis in land planning and natural resource management
contexts.
Determining Visual Exposure (Basis Posting) — A
land planner needs to determine areas are that are highly visible from the road
network for consideration in a new development plan for the county. (Uses MapCalc Learner Tutor25 dbase)

Modeling Visual Exposure from Roads and Houses (Basis
Posting) — A
natural resource manager needs a map that identifies the relative visual
exposure of forested lands in a county. This
information is important in deciding where visually sensitive activities should
and shouldn’t be located. (Uses MapCalc Learner Tutor25 dbase)
