Learning ArcGIS Pro 2 - Second Edition

By: Tripp Corbin GISP

Overview of this book

Armed with powerful tools to visualize, maintain, and analyze data, ArcGIS Pro 2 is Esri's newest desktop geographic information system (GIS) application that uses the modern ribbon interface and a 64-bit processor to make using GIS faster and more efficient. This second edition of Learning ArcGIS Pro will show you how you can use this powerful desktop GIS application to create maps, perform spatial analysis, and maintain data. The book begins by showing you how to install ArcGIS and listing the software and hardware prerequisites. You’ll then understand the concept of named user licensing and learn how to navigate the new ribbon interface to leverage the power of ArcGIS Pro for managing geospatial data. Once you’ve got to grips with the new interface, you’ll build your first GIS project and understand how to use the different project resources available. The book shows you how to create 2D and 3D maps by adding layers and setting and managing the symbology and labeling. You’ll also discover how to use the analysis tool to visualize geospatial data. In later chapters, you’ll be introduced to Arcade, the new lightweight expression language for ArcGIS, and then advance to creating complex labels using Arcade expressions. Finally, you'll use Python scripts to automate and standardize tasks and models in ArcGIS Pro. By the end of this ArcGIS Pro book, you’ll have developed the core skills needed for using ArcGIS Pro 2.x competently.

Dissolve tool

The Dissolve tool is used to simplify or generalize a data layer based on a common attribute value. So, for example, if you had a parcel layer that showed each parcel and each parcel was coded with its designated zoning classification and you wanted to know the total amount of area for each zoning classification within the city, the Dissolve tool can be used to create individual polygons for each zoning classification.

The Dissolve tool can be found in the Data Management Tools toolbox and the Generalization toolset. It works on points, lines, and polygons. Here is an illustration of the example that was described earlier:

As shown in the previous screenshot, the initial parcel layer contained many individual polygons that would have made determining the total area for each zoning classification difficult. Once you use the Dissolve tool, a new layer is created so that each zoning class has a single polygon. From there...
