Wikia Maps is a new map creation tool from Wikia. Wikia Maps has two map creation options. You can use Wikia Maps to create maps in a manner similar to those that you may have previously created in Google Maps. Wikia calls those maps "real maps." The truly cool feature of Wikia Maps is the option to create maps on pictures that you upload. Wikia calls those maps "custom maps."
Custom maps are created in Wikia Maps by uploading a picture or selecting a picture from the Wikia Maps gallery. You could upload a picture of a historical map, a picture from a place that you visited (I'm thinking of my pictures taken from the top of the Empire State Building), or you could upload a picture of a drawing that you made. You can add map placemarks to the image that you upload to use as the basis of your custom Wikia Map.
Applications for Education
My first thought when I saw the custom option in Wikia Maps was that it could be a good tool for students to use to create maps about fictional places they have read about in their favorite books. To do this students would draw a map of what they think a fictional town or fantasy world looks like. After completing the drawing, students would take a picture of it and upload it to Wikia Maps where they can add multimedia placemarks to their maps of fictional places.
