(1) Use a search engine to find two different online data markets. Write a report sharing the sources or focus of information each provides, the availability of visualization tools to preview data, and how developers can access or incorporate the data into their own apps and websites. (2) Use a search engine to find a popular mapping mashup based on data from one of the sources listed above, or another topic. Identify the provider of the data and the provider of the maps on which the details displayed. (3) Use a search engine to find an app or website that will help you create your own map mashup showing locations of your online data: Facebook friends, Flickr or Instagram photos, or Tweets. Take a screenshot of the mashup you made.
