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• won’t cost to maintain after the emergency

responseThis requires a new generation of GIS -- CloudGIS

Ontology Related Research Needs

1) The interoperably integrating currently isolated clouds from multiple domains2) The evolution of cloud from a technology-centered to a human-centered

paradigm3) The advancement of cloud to enable multiple science domains in simulating

complex phenomena4) More study in social sciences is urgently needed to enable efficient governance

and collaboration among team members, communities, and domains5) Work must be done to improve knowledge capturing/sharing/utilizing6) 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
