Add data
Data Layers are the contents of a map. They can include a wide range of information about people, the earth and events. Alongside regular data fields, location is represented as points, lines, and polygons. Your ArcGIS Online subscription gives you access to the ArcGIS Living Atlas of the World - an extensive collection of curated spatial data. In this scenario, we're looking at economic activity across the UK using data from the UK Census 2011 - available in the Living Atlas as polygon data.
