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)

NASA EO-1 Tasking

• Advanced Land Imager
• Hyperion hyperspectral imager

Budalangi Floods November 13, 2008
NASAs 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
7
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

8
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

• 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.

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 Universitys International Research
  Institute (IRI)

11
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.

12
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

13
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.

Current Priorities
15
Visualization Tools
SERVIR-Viz is an open-source desktop Earth browser

• Based on NASAs World Wind
• Provides user-friendly GIS functionality for
  non-experts
• Supports OGC compliant overlays
• Enables users to build custom plugins

16
Decision Support Tools
The SERVIR Climate Mapper tool puts climate
models and other geospatial data directly in the
hands of decision makers
17
Web Services Registry
18
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

19
Directory Services
Tools and services to facilitate networking and
cooperation among African geospatial scientists,
projects and organizations
