Chapter 6 – Introduction to raster GIS

Chapter 6 introduces the raster GIS model and describes the theoretical basis by which it represents the world. It describes how raster data sets are created, discrete and continuous surfaces, the way in which data is stored in grids consisting of rows and columns of grid cells, and integer and floating point raster data sets. It introduces raster operators, expressions, and functions: local, focal, zonal, and global functions for transforming raster data.
