As you’re thinking about your group projects, here’s a mapping tool that you might consider using.
Umapper is a web-based tool that allows you to create an interactive map that is embeddable on a website. In addition to marking your maps with points of interest and plot routes, it also allows you to insert images and annotations. You can even create a geodart game that allows your audience to interact with your map as a game. You can also use a customized map instead of using online map providers like Google or Yahoo Maps.
Please feel free to contact me if you have an idea for a project, but are not quite sure how to carry it out. That’s why I’m here!
