I'm putting together a web mapping app in ArcGIS Online to support a class I'm planning - it essentially shows two choropleths of deprivation levels over the Topographic basemap. I am using a web mapping app so as to access both the Moving Window facility and bookmarked locations with explanatory text.
At a given point in the class, I want the students to think more about the geographic areas being used and how they can include different types of demographic areas and even land uses. The Topographic basemap is ideal for most of the exercise due to its clarity, but it would be great to switch the basemap to World Imagery at this point, since that gives a better sense of housing type and land use.
Can this switch be offered in a web mapping app, or only from the web map itself?
