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.

Creating a Script Tool

Now that the basics of creating and executing ArcPy scripts have been covered, we need to take the next step, and create reuseable "script tools". Creating script tools will allow for greater code reuse, and will make it easy to create custom tools for other GIS analysts and customers. With a Python script "back end", or code, and a familiar ArcGIS tool "front end" or graphical user interface (GUI), the custom script becomes a reliable tool for all users within a GIS work shop.

This chapter will cover the following topics:

  • Adding parameters to scripts to accept input, and produce output as required by the user
  • Creating a custom tool front end and a custom toolbox
  • Setting the parameters of the tool front end to allow it to pass arguments to the code back end
