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.

Referencing projects and maps within projects

The arcpy.mp module can assist you in automating mapping tasks, but it does not remove the need for creating a map in ArcGIS Pro. You will still want to create your maps in ArcGIS Pro, but once created, arcpy.mp can be used to automate tasks such as adding, removing, and styling layers, and exporting maps across maps and projects.

ArcGIS Pro projects are stored as .aprx files. The .aprx file contains any maps with their associated layers, and any layouts with their associated layout elements. In this section, you will be starting with a project that contains two maps and a layout.

  1. Open up ArcGIS Pro, navigate to where you unzipped the Chapter7.zip folder, and open up Chapter7.aprx. You will see two maps in the project, Map and Map1.
  2. The first map, Map, contains the Oakland Vegetation from CalFire (OaklandFVeg), AC Transit Routes (Summer21RouteShape), and AC Transit Stops (UniqueStops_Summer21) from Chapter 2, and Alameda...
