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.

Using arcgis.raster

ArcGIS API for Python (the arcgis module) also contains useful tools for raster layers and imagery layers. Used in combination with arcpy, it can allow you to store rasters or imagery in the cloud, pull down the rasters, perform analysis or a process on the rasters, and then put the rasters back into ArcGIS Online.

Much like arcpy, there are a ton of built-in functions for arcgis that enable you to interact with raster data. These functions allow you, for example, to get statistical properties of the raster such as mean or maximum or minimum cell value, or to perform mathematics on the cell values. Most of these functions are part of the raster subclass of arcgis and are available at arcgis.raster.functions.

Working with imagery layers

In this example, we will load an imagery layer from the web into a map and save it to disk.
