Denise McKenzie gave a presentation on open standards for sustainable development at Locate15 in Brisbane, Australia. She discussed how open standards can help create a "World Wide Web of environmental data" by enabling data discovery, access, and sharing. Key open standards mentioned include OGC standards like GML, CityGML, and Sensor Web Enablement, as well as other emerging standards. Open standards are needed to support environmental monitoring, accounting, and tracking progress on the UN's Sustainable Development Goals.
