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

NASA EO-1 Tasking

• Advanced Land Imager

• Hyperion – hyperspectral imager

Budalang‟i Floods

November 13, 2008NASA‟s tasking request system for EO-1 is used by SERVIR-Africa to

acquire baseline and post-event imagery of flooded areas.

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

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

Model

Flood Potential TRMM 3B42 Precipitation

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

Rapid Flood Mapping using MODIS

Flooding in Mozambique

January 27, 2008

• 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.

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)

Page 13: [Day 4] SERVIR-Africa

www.servir.net/africa

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.

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

Page 15: [Day 4] SERVIR-Africa

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.
