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.

ArcGIS Online tokens

A token is a unique identifier that allows an application or user to access some part of an API. It is basically a complex string that is generated and provided to an application accessing the services provided by the API. In our case, essentially, a token allows an authenticated user access to private or password protected REST services through the ArcGIS REST API.

In order to see the output of an ArcGIS REST API token, we can see the response by passing the parameters it takes through an URL. Navigate to the browser and enter this URL:

Replace youruser and yourpassword with your actual username and password for the ArcGIS Online account you have or set up earlier in the book. When you enter this URL, because we passed f=json...
