The Problem
  • Severe flooding in Namibia (south-western Africa)
    with little warning
  • Existing flood warning models are not very
    precise
  • - Advance warning would reduce loss of life
    and property
  • NASAs EO-1 mission research stakeholders want
    to test the application of SensorWebs in a
    decision support tool for disaster management
  • United Nations coordinated a partnership between
    stakeholders

Introduction
  • What is a SensorWeb?
  • Takes disparate data feeds and unites them in
    cohesive display
  • Used to make analyzing and responding to large
    datasets easier
  • Area of research to EO-1 team for use in analysis
    of image products
  • Namibia Flood Dashboard is an example of a
    SensorWeb, and represents an extension of a
    decade of EO-1 research
  • Project Objectives
  • Aggregate information sources gt better
    situational awareness / decision making
  • Integrate and compare data feeds -gt enhanced
    analysis capability
  • Disseminate information -gt wider availability of
    data products and analysis
  • Rapid configuration and deployment-gt software can
    be rapidly applied to diverse situations

Tool Overview
  • Bulletin System (current and archive)
  • Google Maps/Earth powered geospatial data display
  • River gauge station graphing and comparison
  • Automated EO-1 Tasking (plans for more spacecraft)

Geospatial Display(The Big Map)

EO-1 Observation Request Tasking
  • Tasking request generated based on alerts
  • Request either acted upon or not based on
    priorities
  • Goal task multiple satellites for specific
    observations and bring more sensors into web

Tool Capabilities
  • Automated EO-1 Tasking
  • Rapid delivery of technical information through
    bulletins
  • Access to EO-1 Advanced Land Imager (ALI) data
    products
  • Access to other satellite data products
  • Correlation with infrastructure details
  • Graphing and comparison of river levels
  • Plans to allow even more powerful comparisons,
    such as retrieval of satellite products based on
    ground data comparison

11
River Gauge StationsStart with manual Yardstick
Measurements
12
Map LayersInfrastructure, MODIS Flood Maps,
Flood Classified Images
  • Establish trust in remote sensing models (ground
    validated)
  • Integrate trusted models into decision process
  • Goal better, faster decisions

13
Area of StudyReeds Flooded Region
  • Determining flooded area is complicated by
    vegetation
  • Satellite sensors may do better job than visual
    spot-checks
  • Ground validation used to refine models

14
Future Plans
  • Enable direct daily uplink of river levels
  • Add hydrograph to satellite cross-indexing of
    data products
  • Add Open Street Map (OSM) layer display to
    supplement Google Maps / Earth
  • Add Tropical Rainforest Measuring Mission (TRMM)
    Precipitation Accumulation Calculator
  • (Stretch goal) Direct social impact
  • i.e. tracking and response to hippo attacks

15
Summary
  • Dashboards for SensorWebs allow flexibility and
    rapid integration
  • Cloud technology allows huge datasets, rapid
    processing, and improved reliability
  • SensorWebs will continue to improve satellite
    tasking
  • Global benefit for many remote sensing
    applications
