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.

Field name

In a database table, each field must have a unique name. That name cannot include spaces or special characters, though underscores are allowed. The allowed length of the field name will depend on the type of database. Is it adBase,Access, orSQL Servertable? Each of these has its own limitations.

As a rule of thumb, I have learned that keeping my field names limited to 7 to 8 characters works best. This will prevent field names from getting shortened if you export the data to a different format that does not support the name length of your native database.

This often happens when your GIS data is stored as a geodatabase that supports long field names, but you export to a shapefile that does not. Shapefiles store attributes in a dBase format that does not support long field names. Being an older database type, dBase only supports field names of 7 to 8 characters. So, a field that is named as parcel_indentification_number in your geodatabase may get renamed...
