Spatial Point Patterns
8.1 TYPES OF SPATIALLY EXPLICIT DATA
In this book, we will look at two main types of spatial data: one type corresponds to point patterns
and the other type to lattice arrangements. The difference is whether we consider points or regions
placed over a spatial domain. We will focus on two-dimensional (2D) domains because they
encompass many important geographical and environmental situations.
Point patterns are typically a collection of points placed over a spatial domain. They may be
regular as in a grid or irregular. We may have values of variables associated at each point. Lattice
data correspond to regions or pol ...
