Stony Brook University’s Sustainability Task Force created this green map to “better spread the word and inform people of all the wonderful programs and projects that are either already completed or currently underway” in that university area. The interactive maps has icons by topic such as Admin, Cultural Awareness, Decreases of Carbon Footprint, Energy Consumption, Transportation, etc which you can click on to include or remove from the map. It also lists specific green initiatives (showing the icon) and provides more information about these initiatives. You can mouse over icons on the map and see the topic and click on the link for more information.
Google maps allows users to create custom maps that can be shared with others. A library could create a map of their campus or community area, with icons representing topics or categories, and more information/links, to help guide people to green programs, projects and resources in their area. Any library doing something like this already?
Here is a video explain how to create My Map in Google Maps:
