    GIS programs link attribute data files to digital maps. The previous Chapter focused on the map side of this equation. Let’s focus now on the attribute data files. Like the previous chapter, this chapter examines several key concepts and covers the preprocessing of your GIS data, but it specifically focuses on attributes, data files, and the editing of your attribute data. The concepts focus on attribute data and principles of raster and vector database management. Understanding these concepts will help you to effectively edit and manage your attribute data. The bulk of the chapter focuses on various preprocessing routines including adding and deleting fields, deleting records, joining data files, selecting and sorting records, calculating attributes, and geocoding. The chapter ends with a short discussion regarding attribute verification.
