Data Acquisition Current Priorities for SERVIR-Africa Direct request (tasking) of NASAs 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. NASA EO-1 Tasking Advanced Land Imager Hyperion hyperspectral imager Budalangi Floods www.rcmrd.org, NASAs tasking request system for EO-1 is used by SERVIR-Africa toNovember 13, 2008www.servir.net/africa acquire baseline and post-event imagery of flooded areas. 8. Envisat Ground Station ASAR Advanced Synthetic Aperture Radar MERIS Medium Resolution Imaging Spectrometer AATSR Advanced Along Track Scanning Radiometer Rapid acquisition, mapping, and validationProvides support emergency response www.rcmrd.org, www.servir.net/africa 9. Data ProcessingCurrent 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. 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. Rapid Flood Mapping using MODIS NASAs 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, 2008www.servir.net/africa 12. Other Applications for MODISDesert 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 Universitys International Research Institute (IRI) www.rcmrd.org, www.servir.net/africa 13. Other Applications for EnvisatRift 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. Data Archive & DistributionCurrent 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. SERVIR-Africa: Platform Goals Ensure the SERVIR platforms 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.
