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 create a map to show the habitat area of an endangered species in the United States. The map, along with text and images, will be added to a story using ArcGIS StoryMaps that tells a more complete and engaging story about the endangered species.
In this lesson, you'll focus on an important initiative that will help the Oregon Office of Emergency Management and Morrow County in combating groundwater pollution. As a GIS and environmental planning specialist, you'll identify groundwater vulnerable areas and high-risk zones in Morrow County. You'll prepare and use soil and land-cover data to identify areas where mitigating actions could be taken.
In this lesson, you have a .csv table with the average number of people affected by river flooding each year in each country. You'd like to visualize this data on a map, but it is non spatial: it does not include any geographic coordinates.
You have a feature layer that maps the 47 prefectures of Japan. Later, you'll join tabular demographic data to this layer, filter it, symbolize it, and conduct a series of statistical analyses. Before you begin this project, you'll ensure the spatial data is clean and orderly.
The Japan Prefectures layer has an issue common to many GIS layers: it has too many fields. Most of them are not useful to your specific project. Scrolling through a long list to find the same field over and over again will cost you valuable time and possibly lead to errors. In this lesson, you'll learn how to hide, relabel, and highlight fields to make the layer clean, tidy, and easy to use.
Oceans play a vital role in regulating global climates. Ocean currents circulate warm and cold water, connecting distant regions of the planet, determining regional climates, creating biodiverse ecology, and influencing weather. The ocean has a much higher heat capacity than the land or atmosphere, which means that it heats and cools slowly, moderating the climates of coastal areas. Oceans absorb much of the sun's heat and much of the carbon dioxide created by burning fossil fuels.
However, the oceans are experiencing dramatic changes due to climate change. In addition to rising temperatures, the oceans are suffering from acidification and deoxygenation that threaten marine ecosystems. These effects extend to humans through severe weather, sea level rise, and depleted fisheries. In addition, the warmer the ocean gets, the less ability it has to moderate the effects of climate change on land. In this lesson, you'll download, visualize, and compare data for three of the most important climate change stressors on the oceans: rising temperatures, acidification, and deoxygenation.
