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.

Changing the map view and exporting

At this point, you have added all the elements you need to your map and your legend.

You also have:

  • A list of the GEOIDs within your study area of all the census block groups that have a minority percentage that is greater than the reference community
  • A list and data dictionary that will be used to create the text box containing the specific race population percentages within the selected census block group

In this section, you will use all of the above to export to PDF a map for each of the census block groups with a minority percentage greater than the reference community. All the code in this section is going to be written into two cells, and will contain many print statements so you can track the progress of your code. The first cell is the largest, as it contains the code to loop through the block groups, make all the changes to the map, and export it.

The code for this cell will be split into multiple steps...
