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.

Step 1 – Populating the field using the Field Calculator tool

In this step, you will populate the length of each road segment in miles into the field you created in Exercise 9A. You could do this manually for each segment using some of the edit skills that you have already learned. That would be very time-consuming. There is a much more efficient way.

One of the fields that you identified as being associated with the street centerlines was Shape_Length. So, now you already have values showing the length of each road segment. It is in feet, though to populate your new field with the correct values in miles you will need to convert feet into miles. As you have previously learned in this section, ArcGIS Pro includes a tool called the Field Calculator, which will allow you to populate a field with values based on an expression for all features in the feature class. We will follow the next steps to do so:

  1. Open ArcGIS Pro and the Ex9A project that you...
