ArcPy and ArcGIS - Second Edition

By: Silas Toms, Dara OBeirne

Overview of this book

ArcGIS allows for complex analyses of geographic information. The ArcPy module is used to script these ArcGIS analyses, providing a productive way to perform geo-analyses and automate map production. The second edition of the book focuses on new Python tools, such as the ArcGIS API for Python. Using Python, this book will guide you from basic Python scripting to advanced ArcPy script tools. This book starts off with setting up your Python environment for ArcGIS automation. Then you will learn how to output maps using ArcPy in MXD and update feature class in a geodatabase using arcpy and ArcGIS Online. Next, you will be introduced to ArcREST library followed by examples on querying, updating and manipulating ArcGIS Online feature services. Further, you will be enabling your scripts in the browser and directly interacting with ArcGIS Online using Jupyter notebook. Finally, you can learn ways to use of ArcPy to control ArcGIS Enterprise and explore topics on deployments, data quality assurances, data updates, version control, and editing safeguards. By the end of the book, you will be equipped with the knowledge required to create automated analysis with administration reducing the time-consuming nature of GIS.

Introduction to Python for ArcGIS

In this chapter, we will discuss the development of Python as a programming language from its introduction in the late 1980s to its current state. We will discuss the creator of the language and the philosophy of design that spurred its development. We will also touch on important modules that will be used throughout the rest of the book, and especially focus on the modules built into the Python Standard Library. We will configure Python and the computer to execute Python scripts. The structure of the Python folder will be discussed, as will the location of the ArcPy module within the ArcGIS folder structure. We will also discuss Integrated Development Environments (IDEs)--programs designed to assist in code creation and code execution--comparing and contrasting existing IDEs to determine what benefits each IDE can offer when scripting Python code.

This chapter will cover the following topics:

  • Quick Overview of Python: what it is and what it does, who created it, where is it now
  • Important Python modules, both built-in and third party
  • Python core concepts including data types, data containers, and looping
  • The location of the Python interpreter, and how it is called to execute a script
  • Adjusting the computer's environment variables to ensure correct code execution
  • Integrated Development Environments (IDEs)
  • Python's folder structure, and where the modules are stored
