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.

URL parameters

In order to access data and format it accordingly through the ArcGIS REST API, you will have to provide one string that contains the REST endpoint along with various parameters known as the URL parameters. URL parameters are exactly what they sound like: parameters of the data you want to be returned in a specific format accessed through the Web using the URL as the query syntax. All URL parameters will be in the following format:


In the preceding example, http://<rest-endpoint> is the base URL for the feature or map service you are accessing on your ArcGIS Online or ArcGIS Server instance. The operation is the type of request you are making. For example, you would pass query if you would like to query the data. The ? query string is used to indicate the beginning...
