Overview of this book

ArcGIS is Esri's catalog of GIS applications with powerful tools for visualizing, maintaining, and analyzing data. ArcGIS makes use of the modern ribbon interface and 64-bit processing to increase the speed and efficiency of using GIS. It allows users to create amazing maps in both 2D and 3D quickly and easily. If you want to gain a thorough understanding of the various data formats that can be used in ArcGIS Pro and shared via ArcGIS Online, then this book is for you. Beginning with a refresher on ArcGIS Pro and how to work with projects, this book will quickly take you through recipes about using various data formats supported by the tool. You will learn the limits of each format, such as Shapefiles, Geodatabase, and CAD files, and learn how to link tables from outside sources to existing GIS data to expand the amount of data that can be used in ArcGIS. You'll learn methods for editing 2D and 3D data using ArcGIS Pro and how topology can be used to ensure data integrity. Lastly the book will show you how data and maps can be shared via ArcGIS Online and used with web and mobile applications.

Validating spatial data using a geodatabase topology

You have just created a new topology in the previous recipe. This will allow you to find errors in the parcel feature class which violate the polygons must not overlap rule you included in the topology. To find any errors you must first validate the topology.

When you validate a topology, several things occur. First, all features participating within the topology are snapped together if they are within the cluster tolerance. This is done automatically for all features when you validate. Second, the participating feature classes are checked against the rules you have included in the topology. Any areas that include features that violate the rules are identified in the topology so you can easily locate the errors and fix them.  

In this recipe, you will validate your topology to identify any errors in the Parcels feature class. To do this, you will create a new map and add the topology, along with the Parcels layer, to it.
