#### 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.

## Calculating the volume of a polygon

Another common 3D analysis task is to calculate the volume of the area covered by a polygon feature. This is done by overlaying the polygon feature across a surface and then calculating the volume that exists between the plane created by the polygon features and the surface they overlay.

In this recipe, you will return to the quarry project you worked on earlier. The project engineer has determined the optimum full pool elevation and created a polygon layer for you. He wants you to determine what the total volume of water will be needed to fill the quarry to this level in gallons.

You will use the `Polygon Volume` tool that is part of the 3D Analyst extension to accomplish part of this analysis. You will then use the `Calculate Field` tool to calculate the total gallons required to fill the quarry.
