New Learn Lessons
A Learn Lesson is a step-by-step tutorial that uses a real-world scenario to introduce key ArcGIS tools and workflows. Here's a roundup of new lessons in the Learn ArcGIS Gallery that have appeared in the last month.
In this lesson, you will use ArcGIS Notebooks to create a mean annual precipitation map and configure its pop-up. You will learn how to extract precipitation data at different locations and how to export a raster from the WorldClim image service using the ArcGIS API for Python.

In this lesson, you will learn how to extract precipitation data from a CSV file and create an annual precipitation map using Python and ArcGIS Notebooks.

In the United States, car crashes kill more than 100 people every day and cause an additional 12,000 injuries (Association for Safe International Road Travel, 2021). Beyond the tragic loss of life, the monetary costs of highway crashes are estimated to be more than $871 billion a year. Most of these accidents are preventable.
In this lesson, you'll use ArcGIS Pro to determine when and where car crashes are most likely to occur in Brevard County, Florida. You'll also find where fatalities are concentrated and which intersections are persistent areas for traffic collisions over time. By understanding the spatial and temporal trends of crashes, the county can make informed policy decisions to make its roads safer.

Coral reefs serve as a significant repository of marine biodiversity and are home to about 25 percent of marine species. The health and long-term success of these reefs are critical in maintaining our marine ecosystems. Unfortunately, reefs worldwide face many risks, primarily due to climate change: these risks include ocean temperatures that are too warm for extended periods of time, which endanger coral species and may result in coral bleaching.
In the ArcGIS Pro lesson, you'll use ArcGIS Pro and several years of daily sea surface temperature data to create a model that employs time-series forecasting capabilities to explore the impact of sea surface temperature on coral bleaching. In the ArcGIS Online lesson, your'll create a tiled imagery layer from a NetCDF file containing multidimensional sea surface temperature data for several decades and use analytical tools to locate anomalies in sea surface temperature to help identify areas where coral bleaching may occur.

Various studies have confirmed that racial disparities exist in the practice of police stops. These disparities could be due to many factors, such as institutional racism, individual racial bias, or enforcement of discriminatory policies. In this lesson, you'll learn how to analyze racial disparities in police stop data using data from four different cities. Completing this lesson equips you with techniques that you can apply to police stop data for other locations. GIS has long been used to help police departments understand crime patterns; you will now use these same techniques to examine patterns in policing.
New Learn Paths
A Learn Path is sequenced set of resources for learning about a particular topic. Here's a roundup of some new paths in the Learn ArcGIS Gallery that have appeared in the last month.
