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.

Understanding model components and terminology

Before you can create a model, you need to understand the pieces and parts that form them. Models include a series of connected processes. Each process includes a tool that can be a geoprocessing tool, another model, or a Python script. Each tool has variables that serve as inputs or outputs.

The following diagram shows you two connected processes:

As you can see in the preceding diagram, the model contains two processes built around the Buffer and Union tools. Each of these tools has a number of variables feeding into it. Variables are identified by the blue and green ovals. Notice that the two processes are sharing a variable – Street_Buffer. This variable is an output of the Buffer tool and also an input for the Union tool.

There are three basic types of variables that are included in a model. They are as follows:

  • Data variables: These variables are...
