CHAPTER 20 GENERATING PRESCRIBED PATTERNS IN LANDSCAPE MODELS

The development of spatial optimization and simulation techniques in GIS can greatly improve the quality and efficiency of maps generated to pursue spatial pattern objectives in landscape design and planning. This chapter describes how pattern optimization and simulation can be useful in visualizing alternative possible landscapes and for evaluating landscape planning and design scenarios, and describes various approaches that can be used to generate prescribed landscape patterns. Analyses are presented of performance benchmarks and external factors that affect optimal landscape patterns, using simulated-annealing-based algorithms on hypothetical two-dimensional gridded landscapes. The use and value of landscape simulation in environmental GIS applications is discussed
