Launched in 2009, Open Green Map (OGM) is an online participatory cross-cultural platform for exploring and mapping local green living sites, nature, cultural and social resources around the world. OGM brings local knowledge, universal design and open technology together to benefit all communities. Helping people access essential resources, OGM vibrantly highlights best practices and healthy choices. Everyone is invited to enhance each of OGM's sites with their own images, insights and impact assessments in any language, generating evocative maps with rich, sharable data. The goal of this new media is to give people of all ages and backgrounds the skills, resources and awareness to live more sustainably. OGM uses the familiar Google Map and open source tools to delight and engage casual browsers as well as residents and visitors exploring a specific city, site or theme. Filterable by users, OGM is an innovative and authentic living repository that encourages comparison of site attributes, evolution and outcomes while promoting its replication in new locales. OGM makes patterns of progress and neglect apparent and actionable. It increases levels of participation as people use OGM to dine, shop, get around, work, play and vote. For Mapmakers, OGM breaks down barriers of technology, time and money. Clear instructions, team management and handy resources from web banners to widgets will enable instant publication, promotion and interaction. Designed to maximize social inclusion in the mapmaking process, OGM engages the underserved by highlighting which sites are free and/or welcome children and wheelchair users. Financially, OGM has potential to benefit each site it promotes as well as Green Map System and the local Mapmakers. Preview our sustainable community media vehicle today. Cleanly designed and built to reach encyclopedic proportions, OGM's data will be shared through mobile devices, blogs and other websites to maximize its usefulness worldwide.
