In the new Learn ArcGIS lesson, Fight Child Poverty with Demographic Analysis, you’ll assume the role of someone who works for a charity that supports community programs and poverty relief efforts. Your objective is to ensure the programs are offered where they’re most needed. You’ll create a map by enriching a layer of ZIP Codes with demographic data from ArcGIS Online. You’ll apply smart mapping to ultimately show median household income and child population by ZIP Code area, identifying which areas have the most children living in poverty. You’ll also configure pop-ups so the demographic information for each area is easier to read. Lastly, you’ll report your findings to top donors and partner organizations by configuring a web app that tells a clear story based on your data.

In the new Learn ArcGIS lesson, Download Imagery from an Online Database, use the USGS LandsatLook app to search the USGS database for multispectral imagery of Singapore and find a relatively recent image with low cloud cover. You'll also download the image so you can add it to a map in ArcGIS Pro and change the default band combination to display the image more clearly.

Actionable Intelligence is a new Learn ArcGIS lesson that shows you how military intelligence analysts, during their first field training exercise in California, use ArcGIS Pro to identify and locate the insurgents firing rockets at their base. In this tutorial, you will map data from a spreadsheet with information about enemy attacks and symbolize the data to better understand the battlefield. Then, using spatial and temporal analysis, you’ll discover the patterns behind these rocket launches—information your commander needs to prevent future rocket attacks.

In the new Learn ArcGIS lesson, Classify Land Cover to Measure Shrinking Lakes, you'll calculate the change in area of Lake Poyang in China between 1984 and 2014. Using Landsat imagery, you'll classify land cover in three images of the lake to show only the surface area of the lake. This will allow you to compare the imagery and determine how much the lake has diminished since 1984.

Discover how satellite imagery brings new insight to many of the world's problems. In the latest Learn ArcGIS lesson, Get Started with Imagery, you'll explore various uses of Landsat imagery, which emphasizes features otherwise invisible to the human eye. Using the Esri Landsat app, you’ll start with the Sundarbans mangrove forest in Bangladesh, where you’ll see the forest in color infrared and track vegetation health and land cover. Then, you'll find water in the Taklamakan Desert and discover submerged islands in the Maldives. After using 40 years of stockpiled Landsat imagery to track development of the Suez Canal over time, you'll be ready to explore the world on your own.

In another new Learn ArcGIS lesson, Assess Burn Scars with Satellite Imagery, use Landsat imagery to determine the extent of two fires in Montana's Glacier National Park. Then, calculate a burn index using imagery bands to measure the burn scars, which can provide a baseline for forest regeneration and vegetation succession.

Atlantic salmon populations are in decline, and habitat connectivity is one of many known contributing factors. Dams can block the migration of Atlantic salmon from the ocean to preferred spawning habitat. New dams are built with fishways—artificial waterways that fish use to access areas that are otherwise unreachable. Many older dams, however, are not outfitted with fishways, rendering huge stretches of suitable spawning habitat inaccessible to migratory fish. 

In the new Learn ArcGIS lesson, Connect Streams for Salmon Migration, you'll evaluate dams in the Mersey River of Nova Scotia, Canada, to find the best location to retrofit a dam with a fishway. Then, you'll use ArcGIS Online analysis tools to estimate how much additional salmon breeding habitat could be made accessible by constructing the fishway.

In recent years, Denmark has experienced a number of sudden, extreme rainfall events. To help municipalities prepare for future cloudbursts, the Task Force on Climate Change Adaptation has made a map identifying bluespots: low-lying areas that have no natural drainage. In a cloudburst, bluespots fill up and overflow, damaging nearby buildings. A new Learn ArcGIS lesson, Find Areas at Risk of Flooding in a Cloudburst, presents a geoprocessing model for finding bluespots and assessing the risk to buildings.
