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.

 

Inspect assets with oriented images (ArcGIS Online, ArcGIS Experience Builder, ArcGIS Quick Capture, smartphone or tablet)

When performing any kind of property or infrastructure inspection, photos are necessary for data capture and decision making, while GIS is integral for mapping and analysis. However, it can be difficult to incorporate photos taken from many different angles into GIS. Oriented Imagery, a widget compatible with multiple ArcGIS products, solves this problem by allowing you to manage and visualize imagery taken from any angle or vantage point. Oriented Imagery can also be used in damage assessments, environmental studies, asset inventories, or any GIS workflow that uses photo imagery.

In this lesson, you'll perform a photographic site inspection using GIS. First, you'll create a feature layer to contain images collected in the field. Then, you'll make an ArcGIS QuickCapture project and enable Oriented Imagery so field workers can take photos of your site using their mobile devices. After capturing a few photos, you'll display them in an ArcGIS Experience Builder web app so you can explore the results from your computer.

 

Get started with Map Viewer Classic (ArcGIS Online)

Map Viewer Classic allows you to create and interact with online maps. First, you'll explore an existing web map that shows Hawaii's volcanoes, volcano shelters, and volcano hazard zones. Next, you will reconstruct the web map you explored by searching for and adding layers to an empty web map. Once you add the necessary layers, you will modify symbology and customize other map properties, such as the organization of attributes that display when you click a feature on the map. Last, you'll share your map as a professional-looking web app so other users can explore it.

 

 

 

 

 

 

Get started with ArcGIS Experience Builder (ArcGIS Online, ArcGIS Experience Builder)

You'll use ArcGIS Experience Builder, which allows you to build custom web layouts without writing any code. Your goal is to build a layout that meets the following criteria:

• The map should be the main focus of the app.
• The app should allow users to search for their own address or areas of interest.
• The app should include dynamic text and charts to allow users to explore and interact with the data.
• The map should be paired with a journalistic story.
• The app should work on a mobile device as well as a desktop computer screen.

 

Identify infrastructure at risk of landslides (ArcGIS Online, ArcGIS Image for ArcGIS Online)

Parts of the island of Grenada are susceptible to landslides due to high levels of rainfall, steeper slopes, and various soil types. Having recently acquired high-resolution aerial imagery and elevation data, the country wants to update its GIS buildings dataset and identify infrastructure in areas that are susceptible to landslides. To support this effort, you will upload aerial imagery for a portion of Grenada and use deep learning analysis in ArcGIS Image for ArcGIS Online to extract building footprints from the imagery. Then, you will use raster analysis tools in ArcGIS Image for ArcGIS Online to classify the island according to landslide susceptibility and identify at-risk buildings.
