Aiming to link the multiple visions for the next phase of GIS development, this paper suggests that the emerging Open GIS should serve as a guiding concept. Contextualized in the broader literature of open science, this paper proposes Open GIS should include eight dimensions related to data, software, hardware, standards, research, publication, funding, and education. For the GIS community, Open GIS offers four exciting opportunities: a) technology-driven opportunities for addressing challenges posed by the (spatial) big data deluge; b) application-led opportunities for improving individual and collective decisions; c) curiosity-inspired, crowd-powered opportunities for the development of an open and geographic citizen science for understanding the changing planet; d) education-focused opportunities for implementing the vision of a spatial university. Although there are academic, legal, social/political, and environmental impediments for the practice of Open GIS, Open GIS will become increasingly important in shaping our research and educational agendas in the future. %U https://www.progressingeography.com/EN/10.11820/dlkxjz.2014.06.001
