2 Spatial Ontology Community of Practice Workshop, USGS, Dec.2, 2011 Why a CloudGIS? flooding analyses

3 Spatial Ontology Community of Practice Workshop, USGS, Dec.2, 2011 Why a CloudGIS? What if we can Integrate all geospatial data, information, knowledge, processing in a few minutes Generate and send the right information in real time to the people including decision makers, first responders, and other stakeholders This dream requires a platform and GIS that can be ready in a few minutes can reach out to all people needed only cost for the amount of system used wont cost to maintain after the emergency response This requires a new generation of GIS -- CloudGIS

10 Spatial Ontology Community of Practice Workshop, USGS, Dec.2, 2011 A Conceptual Framework for CloudGIS Yang C., Bambacus M., Benedict K., Nebert D., Mochuney D., Hazlett S., Houser P., Raskin R., Xu Y., Fay D., Rezgui A., Huang Q., and Xu C., Using Metadata, Data/Service Quality and Knowledge to Facilitate Better Data Discovery, Access, and Utilization for Supporting EarthCube,

11 Spatial Ontology Community of Practice Workshop, USGS, Dec.2, 2011 Ontology Related Research Needs 1)The interoperably integrating currently isolated clouds from multiple domains 2)The evolution of cloud from a technology-centered to a human-centered paradigm 3)The advancement of cloud to enable multiple science domains in simulating complex phenomena 4)More study in social sciences is urgently needed to enable efficient governance and collaboration among team members, communities, and domains 5)Work must be done to improve knowledge capturing/sharing/utilizing 6)Improved methods for generating and capturing metadata as a parallel process with data product generation 7)Thinking and computing in a spatiotemporal fashion will provide an enabling capability for the new geoscience frontier by contributing essential computing architectures, algorithms, and methodologies 8)To investigate the connections and interactions across different geospatial subsystems
