Python for ArcGIS Pro

By: Silas Toms, Bill Parker

Overview of this book

Integrating Python into your day-to-day ArcGIS work is highly recommended when dealing with large amounts of geospatial data. Python for ArcGIS Pro aims to help you get your work done faster, with greater repeatability and higher confidence in your results. Starting from programming basics and building in complexity, two experienced ArcGIS professionals-turned-Python programmers teach you how to incorporate scripting at each step: automating the production of maps for print, managing data between ArcGIS Pro and ArcGIS Online, creating custom script tools for sharing, and then running data analysis and visualization on top of the ArcGIS geospatial library, all using Python. You’ll use ArcGIS Pro Notebooks to explore and analyze geospatial data, and write data engineering scripts to manage ongoing data processing and data transfers. This exercise-based book also includes three rich real-world case studies, giving you an opportunity to apply and extend the concepts you studied earlier. Irrespective of your expertise level with Esri software or the Python language, you’ll benefit from this book’s hands-on approach, which takes you through the major uses of Python for ArcGIS Pro to boost your ArcGIS productivity.

Creating and adding data to your map

You now have a layout that is ready for creating your map automation. It contains:

  • The existing Transbay bus routes
  • The Transbay bus routes that were suspended
  • The race data by block group displayed using dot density symbology

The legend is set up to add in the new layers you will be creating using ArcPy in an ArcGIS Pro Notebook.

The final product will be a map series for a suspended bus line that highlights each block group within a 0.5-mile study area of the route with a minority population larger than that of a reference community. The reference community is the minority percentage of all the block groups within 0.5 miles of the routes that were not suspended. This will allow you to understand how many block groups in the suspended line have a higher percentage of minority population than the population along the bus routes that remained.

Each block group with a minority percentage higher than the reference...
