How Can Geospatial Technologies Help in Knowledge Building? EO Systems (spaceborne & airborne) – SENSORS with various SPATIAL, TEMPORAL SCALES, EM REGIONS – GEOPHYSICAL PRODUCTS from RS GIS – Link, view, analyse all geo-linked data GPS – LOCATIONS, MOBILE MAPPING (INTEGRATION) : Sensor-Web, Web-GIS, Crowdsourcing GI, Mobile Mapping, Spatial/ Non-spatial Databases, AWS, etc. APPLICATION : Modelling & Decision Making with knowledge
Regional Local Earth Observation From Space Multi-resolution Capability (Low Res.) (High Res.)

High temporal resolution Large swath Medium temporal resolution Large swath Low temporal resolution Limited swath Low temporal resolution Very limited swath High spatial resolution Location specific information Coarse spatial resolution Regional level information Medium spatial resolution Local level information Depends on Phase of the disaster Type of the disaster Extent and severity …. Low spatial resolution Global level information Global to Local Spatial Vs. Temporal Resolutions – Trade-offs
Location Based Services and Mobile GIS Mobile Mapping – Integration of 4 Technologies Lightweight hardware GPS Telecommunications GIS
Automatic Weather Stations Affordable alternatives to get detailed weather information like rainfall, humidity, temperature, etc. Special sensors for measuring soil moisture Data transmission through communication satellites Consistency in data recording Enhanced frequency of coverage Coverage of inaccessible areas, all weather and all time operations

The interoperability framework for accessing and utilizing sensors and sensor systems in a space-time context via Internet and Web protocols A set of web-based services may be used to maintain a registry of available sensors. The same web technology standards for describing the sensors’ outputs, platforms, locations, and control parameters, thus ensuring interoperability.. Some Solutions: Sensor Web
Past 2-D flat map displays – User as observer from 2-D description to 4-D interaction Future Effective 3-D visualization 4-D incorporation of time: “The time has come for time.” – Via agent-based modeling / cellular automata? Or how? agents (e.g. vehicles, fires or people) interacting over time in a raster (cell)- based environment according to established rules 5, 6 and 7-D incorporation of touch (pressure, texture, temperature), sound and smell into modeling/simulation environment) User as participant – Users (researchers, professionals, the public) interact with the model; – Participatory GIS: the public as the planner. Move from 2-D description to 4-D interaction and beyond?

Using Crowdsourcing & VGI Technologies in Disaster Applications Challenge New mechanism for voluntarily producing & disseminating geographic information using ICT/web-based mapping services (Goodchild, 2007). Especially useful in disaster/ emergency applications where real-time updated information (in case of a disaster) is required or where spatial information is not adequate. Examples – Wikimapia, OpenStreetMap, Google MyMaps, etc. Success Stories – Haiti Earthquake of 2010, Wild Fires of Sanata Barbara (USA) in 2007-09, etc. Integration of crowdsourced & authoritative data? Data quality? Credibility of contributor?
