3Why Cloud Computing? Flooding We need the right information to the right place and right people almost in real time, when flooding happened.
4Why Cloud Computing? Flooding Analyses The Hurricane Katrina response took about one week to integrate and develop relevant response geospatial information. The time is too long for responding.
5Why Cloud Computing? What if we can Integrate all geospatial data, information, knowledge, processing in a few minutesGenerate and send the right information in real time to the people including decision makers, first responders, victimsThis dream requires a computing platform thatcan be ready in a few minutescan reach out to all people neededonly cost for the amount of computing usedwon’t cost to maintain after the emergency responseThis is exactly what cloud computing can provide
6Cloud ComputingCloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.The Most popular definition is developed by NISTNIST 2010
7Cloud ComputingFive essential characteristics, which differentiate cloud computing from grid computing and other distributed computing paradigms:On-demand self-service. provision computing capabilities as needed automatically.Broad network access. available over the network and accessed through standard mechanisms.Resource pooling. computing resources are pooled with location independenceRapid elasticity. Capabilities can be rapidly and elastically provisioned.Measured Service. automatically control and optimize resourceNIST 2010
8Cloud Computing Three service models Software as a Service (SaaSCloud), such as gmailPlatform as a Service (PaaS), such as MS AzureInfrastructure as a Service (IaaS), such as Amazon EC24. Data as a Service (DaaS)NIST 2010
9Geospatial Science Information Workflow IT Characteristics:Data IntensityComputing IntensityConcurrent Access Intensity, andSpatiotemporal IntensityGeospatial sciences has four IT related characteristics. But all of them attribute to the last one, spatiotemporal intensity of the problem, the data resources, the end users, and the computing resources.
10Spatial Cloud Computing Refers to the distributed computing paradigm thatEnables the geospatial science discoveries, emergency responses, education, other societal benefitsIs optimized by spatiotemporal principles.Yang C., Goodchild M., Huang Q., Nebert D., Raskin R., Xu Y., Bambacus M., Fay D., Spatial Cloud Computing: How can geospatial science use and help to shape cloud computing?

12Natural Hazards: Dust Storms Forecasting & Visualization ObjectivesProvide timely forecasting of dust storm for public health emergency responsesProvide an intuitive interface for decision makersEnabling Computing TechnologiesCloud Computing as an advanced cloud computing platform to support simulation and forecasting.Cloud DB as a data management tool for large volumetric data.4D/5D Vis Tool to render the data.Dust storm is a typical problem with the four characteristics. Cloud computing and 5D processing technologies are needed.
135D visualization from 2D to 3D space, 4D (space+time), and 5D (+phenomena, such as dust)
14Computing IntensityThe computing is very intensive and spatiotemporal related. Lots of researches are needed to enable this. Such as this one on how to leverage the biggest number of CPUs and processes.
15GEOSS Clearinghouse Objectives Share Global Earth Observation Data Among 140+ Countries to Address Global Challenges of Natural Hazards and Emergency ResponsesSupport Global End Users to Discover, Access, and Utilize EO DataProvide Responses to End Users in SecondsAdvanced Computing TechnologiesCloud Computing (EC2 & Azure) Responds to Spike Massive Concurrent End UsersCloud DB (SQLAzure) Manages Millions to Billions of Metadata RecordsWebGIS & 5D Vis Tools to Visualizes EO Data
16The discovery, access, and utilization of data can be integrated into one platform with this open simple search. But the problems is on how to get response in time with proper accuracy, knowledge, and large volume of data.
17This one show if the users are spatiotemporally distributed around the world.
18Concurrent IntensityCloud can help, detailed in the first paper in references.

23Potential Research Directions Spatiotemporal principle, thinking, and comptuingImplement important complex geospatial science and applications for best practiceSupporting the SCC characteristicsSecurityCitizen and social science issues: Trustworthy, Privacy, Ethical, etc.Many other (scholar) aspects of geospatial sciencesMany research needs to be done. One if on security, there is no silver bullets on this. Organizational research & development is to standardize the requirements and products so end user can match their security needs to providing with relevant costs.
