East Rock Park: Inside and Out is an interactive web based project empowering local communities to map how they use a local park – East Rock Park. The website was created to explore emerging community mapping technologies and uses like neogeography. Since the introduction of geobrowsers, like Google Maps, the layperson has been empowered to create and share spatial information over the internet with ease. Can community groups or neighbors ban together to apply these technologies to map their communities and local ecosystems? This paper examines community mapping trends, the technologies associated with neogeography and details the process of creating the Inside and Out website.
