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)

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

River Gauge StationsStart with manual Yardstick
Measurements

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
