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.

Field data collection is an important way users interact with ArcGIS Online. Through the use of apps like Field Maps and Survey123, field staff can collect data. That data can be stored as a feature layer or feature layer collection on ArcGIS Online. On many occasions, it is necessary for field staff to take pictures of the data they are collecting.

Reviewing those pictures on ArcGIS Online or in the app the data was collected in is useful, but sometimes the pictures need to be downloaded from your account. While this can be done by exporting the feature layer to a geodatabase and then running a tool in ArcGIS to extract the photos, the photos do not have names associated with the features. It would be useful for the photos to have names of attributes from the feature layer.

In the case study for this section, you have been collecting survey data from Survey123 on farmers’ markets in Oakland and Berkeley, which checks...
