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.

Updating and fixing data sources

Updating data within a map can be a time-consuming process. It can involve many clicks to get into a dataset’s properties to change the data source to a new dataset, which becomes frustrating when multiple links are broken due to geodatabases being moved.

Luckily, the arcpy.mp module has a class that allows you access to the layers in your map. You will be exploring many of the properties available in the layers class throughout this chapter. First, you will look at how to use the updateConnectionProperties() method on the layers class to fix broken links.

Fixing broken links

It can be frustrating to see the red exclamation point of a broken link on multiple layers when you open a map. The data is not displaying and you have to click through the properties of multiple layers to fix the broken link. The updateConnectionProperties() method in the layers class of the arcpy.mp module can simplify the process and be used to automate the...
