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.

Exporting the model and adjusting the script

While modeling analysis in ModelBuilder has its drawbacks, there is one fantastic option built into ModelBuilder: the ability to create a model, and then export the model to Python. Along with the ArcGIS Help Documentation, it is the best way to discover the correct Python syntax to use when writing ArcPy scripts.

Create a folder that can hold the exported scripts next to the SanFrancisco geodatabase (for example, C:\\ProjectsScripts). This will hold both the exported scripts that ArcGIS automatically generates, and the versions that we will build from those generated scripts. Now, perform the following steps:

  1. Open up the model called Chapter2Model1.
  2. Click on the Model menu in the upper-left side of the screen.
  3. Select Export from the menu.
  4. Select To Python Script.
  5. Save the script as
Note that there is also the option...
