“Mashups” are the common word to describe the result of combining the features and information of two or more websites or tools.
“Mashing” data together with a map is one “mashup” that can make information more accessible to English Language Learners.
Virender Ajmani has a blog called MIBAZAAR where he shares mashups he creates using data and Google Maps. I’ve posted about several of his creations in the past. His newest one highlights CNN’s ranking of what they think are the 100 best places to live in the United States.
If you go to his blog, you’ll see a listing of his previous mashups on the sidebar. They’re worth a visit.
