You will learn: how to find and use spatial data that others have shared on the ArcGIS Platform.
Organizations all over the world use ArcGIS to create and manage their spatial data. Many of them share their work publicly through ArcGIS Open Data, the Living Atlas or ArcGIS Online. Because of this you can often find a relevant existing layer in the area you're studying if you take the time to search for it. Do note that it's up to you to evaluate the coverage, quality, recency, and accuracy of the third-party open content you find. In this lab, you'll practice searching for interesting data sets on ArcGIS Open Data.
