[Day 4] SERVIR-Africa

  1. 1. SERVIR-Africa Regional Visualization and Monitoring System www.rcmrd.org, www.servir.net/africa www.servir.net
  2. 2. SERVIR The Regional Visualization and Monitoring System “to serve” Enabling the use of earth observations and models for timely decision making to benefit society • Data and Models • Online Maps • Visualization • Decision Support • Training • Partnerships
  3. 3. SERVIR Nodes and Coordination Office
  4. 4. The SERVIR Team Building regional to national to local relationships through SERVIR geosciences platforms and people SERVIR-Mesoamerica SERVIR-Africa Clayton, Panama Nairobi, Kenya at CATHALAC at RCMRD SERVIR Test-Bed and Coordination Office NASA/Marshall Space Flight Center Huntsville, Alabama
  5. 5. SERVIR-Africa: Applications Tangible results making a difference in people‟s lives • Disaster Analyses • Environmental Monitoring • Health Risk Assessments • Climate Change and Biodiversity • Short Term Weather Prediction Flood forecasting and post- event flood mapping Potential impacts of Fire „hot spot‟ monitoring Rift www.rcmrd.org, mapping Valley Fever risk climate change on biodiversity www.servir.net/africa
  6. 6. Data Acquisition Current Priorities for SERVIR-Africa • Direct request (tasking) of NASA‟s Earth Observing-1 (EO-1) • Envisat products from RCMRD ground receiving station: MERIS, ASAR, AATSR • Daily products from MODIS in near-real time • Meteorological data and ground data to support flood model development • 3-hourly multi-sensor NASA TRMM 3B42 precipitation product in near-real time for input to flood potential mapping • Digital elevation data derived from ASTER and SRTM • Roads database developed from ASTER by the ICSU- CODATA roads working group (CIESIN and AIST) • GEONETcast receiver being installed www.rcmrd.org, www.servir.net/africa
  7. 7. NASA EO-1 Tasking • Advanced Land Imager • Hyperion – hyperspectral imager Budalang‟i Floods www.rcmrd.org, NASA‟s tasking request system for EO-1 is used by SERVIR-Africa to November 13, 2008 www.servir.net/africa acquire baseline and post-event imagery of flooded areas.
  8. 8. Envisat Ground Station • ASAR – Advanced Synthetic Aperture Radar • MERIS – Medium Resolution Imaging Spectrometer • AATSR – Advanced Along Track Scanning Radiometer Rapid acquisition, mapping, and validation Provides support emergency response www.rcmrd.org, www.servir.net/africa
  9. 9. Data Processing Current Priorities for SERVIR-Africa • Implementation of flood potential and forecast models (e.g. US Army Corps of Engineers Hydrologic Modeling System (HEC-HMS) at RCMRD • Automated near-real time flood mapping with MODIS using methodology developed by the Dartmouth Flood Observatory and NASA • Post-event flood mapping and validation using high resolution satellite data • Rift Valley Fever risk mapping and validation www.rcmrd.org, www.servir.net/africa
  10. 10. Flood Potential & Forecast Mapping • Using a regional/global hydrologic model with near-real time precipitation from the multi-sensor NASA TRMM 3B42 precipitation product to derive flood potential • Provides an estimate of expected depth of flood inundation at a 0.25 degree resolution (approx. 25 km) • Precipitation forecast data can be used with the model to provide longer lead time forecasts Model www.rcmrd.org, TRMM 3B42 Precipitation Flood Potential www.servir.net/africa
  11. 11. Rapid Flood Mapping using MODIS • NASA‟s MODIS Rapid Response System provides SERVIR with imagery and data within 5-6 hours from acquisition. • These products are used to create rapid flood maps using a semi-automated approach developed by the Dartmouth Flood Observatory. • NASA is working to reduce the lag time to less than 3 hours, and trying to fully automate the MODIS flood mapping process. Flooding in Mozambique www.rcmrd.org, January 27, 2008 www.servir.net/africa
  12. 12. Other Applications for MODIS Desert Locust Areas • MODIS reflectance and vegetation index data can illustrate changes in vegetation conditions which provide ideal breeding conditions for Desert Locusts • SERVIR-Viz provides an interactive tool for analyzing MODIS time series products from the Columbia University‟s International Research Institute (IRI) www.rcmrd.org, www.servir.net/africa
  13. 13. Other Applications for Envisat Rift Valley Fever • NDVI derived form MERIS Reduced Resolution can be combined with Sea Surface Temperature (SST) data of the Pacific and Indian oceans derived from AATSR to predict the risk of Rift Valley Fever. www.rcmrd.org, www.servir.net/africa
  14. 14. Data Archive & Distribution Current Priorities for SERVIR-Africa • Document existing RCMRD data resources • Establish metadata catalog and ensure that all products are systematically archived • Implement Web portal for data search and download • Implement OGC-compliant web mapping services www.rcmrd.org, www.servir.net/africa
  15. 15. SERVIR-Africa: Platform Goals • Ensure the SERVIR platform’s long-term sustainability in Africa. • Provide support for disaster monitoring and emergency response. • Provide data and services to serve a wide range of other decision-support needs. • Raise public awareness and promote general use of the system. • Increase participation (user contributions) through incentive technologies and platforms.
  16. 16. SERVIR Platform: User Perspective Discover • Managed knowledge base • Catalog services • Directory services • Notification services Share Acquire • Browse & search function • Metadata authoring tools • Ground receiving station • Community building tools • Data acquisition services • Feedback mechanisms Web portal • Data processing services • Reducing barriers to • Data archive sharing • Geodata services Use / Create • Visualization tools • Decision support tools • Forecasts and models • Support for interoperability • Support for product use Current Priorities
  17. 17. SERVIR Platform: System Perspective Desktop Clients Mobile Devices Web Browser Web / Application Server WMS / WFS Web Framework Mapping Engine Server Side Apps Database Systems Additional Services Metadata catalog Caching and tiling Database for Web Framework Extended GIS functionality Application databases Data processing Non-spatial Archive Spatial Data Archive Document files Vector files Media files Raster files Tools and applications Spatial database Operating Systems RCMRD Internal Networks & Firewall External Data Systems SERVIR Ground Systems
  18. 18. Visualization Tools SERVIR-Viz is an open-source desktop Earth browser •Based on NASA‟s World Wind •Provides user-friendly GIS functionality for non-experts •Supports OGC compliant overlays •Enables users to build custom plugins
  19. 19. Decision Support Tools The SERVIR Climate Mapper tool puts climate models and other geospatial data directly in the hands of decision makers
  20. 20. Web Services Registry
  21. 21. Web Services Registry Will be accessible through a new map component being developed for the SERVIR-Africa Web portal •Manage web services provided by SERVIR and others in a structured interface •Initially provide simple mashup capabilities •Ultimately adding data querying and reporting capabilities
  22. 22. Directory Services Tools and services to facilitate networking and cooperation among African geospatial scientists, projects and organizations
