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.

Build a 3D globe app with the ArcGIS API for JavaScript (ArcGIS API for JavaScript)

This lesson provides an introduction toArcGIS API for JavaScript, describing how to create the Half-Earth Project globe as well as a data uploader to visualize shapefiles on it. For analysis of this data, the resolution has to be adequate. Learn more about analyzing biodiversity data in this lesson.

Examine racial inequities in unsolved murder cases (ArcGIS Pro)

In this lesson, you'll use statistical analysis in ArcGIS Pro to identify American cities where unsolved homicides are most prevalent. Then, you'll assess which segments of the population are most impacted and determine whether there is any racial or demographic inequity in regards to unsolved homicides. This workflow doesn't address why homicides remain unsolved; the reasons are complex and varied. But as you work through the lesson, you'll have opportunities to think about possible causes and implications.

Interpolate values (ArcGIS Online)

In this lesson, you'll use interpolation to predict the elevation pattern across the state of Oaxaca, Mexico, and predict the air quality pattern across India.

Share raster data as an analytical image service (ArcGIS Pro)

Imagery is an integral component to creating visually appealing maps that can provide a more realistic perspective of your data for mapping and visualization. While imagery is great for mapping and visualization, you can also use it for analytical purposes. You will combine several image layers for each island in Hawaii into a mosaic dataset. Once you combine the images into a mosaic dataset, you will include it in a land cover classification story produced by NOAA's Office for Coastal Management. The story is a map tour of the land cover classes in NOAA's Coastal Change and Analysis Program (CCAP), but it currently does not include Hawaii. Your goal is to create a map layer for Hawaii to complete the story and publish it to ArcGIS Image Server for others to use. When complete, the image layer will show land cover types in various maps, but it may also be used directly in ArcGIS Pro for analysis to count the area of the different types of land cover.

Use infographics to understand total addressable market (Business Analyst Web App)

A railway company operates rail lines throughout Iowa. The railway company wants to understand the consumer and business market near its intermodal and grain facilities to better serve the Iowa farming community, as well as a set of target industries whose products are less costly to transport by rail. The marketing manager for the railway wants to find businesses in specific industries, located at various distances from the lines, to understand the total addressable market (TAM). The manager wants to present this information to railway executives to launch a campaign targeted to businesses nearby.

First, you'll map rail lines in Iowa in ArcGIS Online. You will add data about active rail lines in Iowa. Then, you will add buffers around these routes and import this layer to ArcGIS Business Analyst Web App. Finally, you will create an infographic to show market prospects within 1, 3, and 5 miles of the rail lines.

Evaluate Ethiopia’s changing landscape (ArcGIS Pro/ArcGIS Image Analyst)

Ethiopia is currently experiencing the largest infestation of desert locusts to hit Eastern Africa in decades. The United Nations' Food and Agricultural Organization is calling the locust invasion "an unprecedented threat to food security and livelihoods" as a result of a decline in vegetation coverage and crop productivity throughout the country. In the past few decades, Ethiopia has also changed due to population growth, resulting in expanding urban areas and agriculture, to the detriment of forest and other natural vegetation, in populated regions of the country.

To analyze these different types of land cover change in Ethiopia, you will use the Change Detection Wizard in ArcGIS Pro. First, you'll analyze long-term land cover changes from 1992 to 2018 using a land cover dataset. Then, you'll identify areas where there has been vegetation loss due to locust infestations in 2020, using imagery data.

New Learn Paths

A Learn Path is sequenced set of resources for learning about a particular topic. Here's a roundup of new paths in the Learn ArcGIS Gallery that have appeared in the last month.

Enter data faster and more accurately in Survey123 (Survey123)

Explore the different ways you can improve the quality and speed of data collection with Survey123.

Getting started with Police Transparency (Police Transparency solution)

Learn how law enforcement agencies can use the Police Transparency solution to share authoritative information and communicate engagement efforts that build trust with the general public and community stakeholders.

Learn Python with ArcGIS Notebooks (ArcGIS Online Notebooks)

Learn how to use Python in ArcGIS Notebooks. This path contains a set of ArcGIS Online Notebooks that you can use to learn how to create Python code for data visualization, analysis, and management on any platform, via ArcGIS Online.
