In chapter 5, we address issues of measurement, sampling, and boundaries. Topics include how to choose a sampling method for spatial analysis; the difference between primary and secondary data; and a discussion of concepts, variables, and attributes. From a sampling standpoint, we focus on using probability and nonprobability sampling and on spatial sampling considerations for stratification, data interpolation, and modeling. The crux of the chapter is how to incorporate spatial elements into a sampling design.
