Chapter 7 – Using raster GIS to resolve conflicts between the
natural and built environments

Chapter 7 describes how to set up a raster analysis environment, convert data between vector and raster formats, and reclassify raster data. It describes common raster GIS operations such as analyzing straight-line distance, creating Thiessen polygons (distance allocation), mapping density, and analyzing surfaces. Using Inverse Weighted Distance (IWD) interpolation as a starting point, chapter 7 describes interpolation. Chapter 7 describes map algebra and how to use functions and operators to change cell values. The final section of chapter 7 describes raster representation, suitability, and process models. Chapters 6 and 7 provide essential information for students to do exercises 3 and 4.
