Bing Maps has a collections feature that you can use to create thematic collections of places. In this brief video I demonstrate how I created a small collection of National Parks in Bing Maps and how I enabled sharing of that collection.
Applications for Education
Creating and sharing a thematic collection of places in Bing Maps could be helpful in preparing an introductory geography lesson. It can also be an activity that you have students do to create a collection of places related to a theme that you assign to them.
