Data Editing and Topology

Abstract

This chapter provides a comprehensive explanation of data editing and topology, delving into the processes of simple, advanced, and topological editing. Real-world examples are extensively used to illustrate these editing techniques. The utilization of basic editing tools is explored, covering tasks such as deleting, moving, splitting, resha**, modifying, merging, and digitizing missing feature classes. Advanced editing techniques are discussed, focusing on addressing common digitizing errors like overshoots and undershoots, generalizing line features, smoothing polygon feature classes, and updating spatial data. The chapter also demonstrates the application of topology rules in data editing, including considerations of coincidence, shared geometry, and feature creation. The topological editing approach is presented as a means to identify and rectify topological errors. Two scenarios are examined to showcase topology editing: the first involves resolving dangles along a fault feature class using both the geodatabase and map topology, while the second scenario addresses non-coinciding watersheds by employing the “Must Cover Each Other” rule.
