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.

GIS glossary

Adding data from a table

As you are creating expressions to generate labels or symbology, you will need to pull data from the layer's attribute table. This is done by using a syntax that starts with $feature, as in the following code:

$feature.Land_Value

As you can see from the preceding code, $feature is an example of a global variable. This is followed by a period and then the field name that you wish to retrieve the value from.

This would return a label displaying the land value for a feature or generate a symbol for each land value.

In the next section, we will introduce variables in Arcade expressions.
