ABSTRACT
Chapters 1 through 8 of this book have introduced the main issues involved in the handling of vector and raster data on the computer. Many of the main data structures for handling these two forms of spatial have been described as well as a selection of algorithms for carrying out some fundamental operations. In Chapters 9 through 11, we will consider two types of spatial data which can be represented using either vector or raster data. In the case of surfaces, we will see that raster data structures and algorithms have some advantages over vector, and in the case of networks, the opposite is true.
