  1. Sentinel: Dynamic Fire Location Mapping

  2. Near- Real Time Emergency Mapping ‘Sentinel’ Satellite Mapping of Fire Hotspots Environmental Remote Sensing Group CSIRO Land and Water Defence Imagery & Geospatial Organisation

  3. Collaborators • FundingDefence Imagery and Geospatial Organisation (DIGO) • ImageryGeoscience Australia (GA) • ImplementationCSIRO • Using NASA and University of Maryland algorithms • Based on GeoMAC fire site hosted by the USGS.

  4. DIGO’s needs • Support Defence personneldeployed in civil emergencies • Continental solution • Identified MODIS data as a possible solution

  5. Key Requirements • All Australia Hotspot Mapping by December 2002 • Satellite to Website in One hour. • MODIS sensor selected • for it’s dynamic range • it’s revisit frequency • Terra and Aqua platforms

  6. Key Requirements • Background imagery • for context • underneath the ‘hotspots’ • by 6 am AEST (18:00 UTC). • Maps with fire locations delivered as • electronic graphic images (web map interface) • faxable B/W map products • email data distribution.

  7. “SENTINEL” ProjectDaily Hotspot Detection Example Dec. 26 – Jan. 10 Sequential days in different colours January 1 – 24 ‘02

  8. Terra Satellite Launched December 18,1999 MODIS MOPITT ASTER MISR CERES

  9. MODerate-resolution Imaging Spectroradiometer (MODIS) • NASA, Terra & Aqua • launches 1999, 2002 • 705 km polar orbits, descending (10:30 a.m.) & ascending (1:30 p.m.) • Sensor Characteristics • 36 spectral bands ranging from 0.41 to 14.385 µm • cross-track scan mirror with 2330 km swath width • Spatial resolutions: 250 m (bands 1 - 2) 500 m (bands 3 - 7) 1000 m (bands 8 – 36) • 2% reflectance calibration accuracy • onboard solar diffuser & solar diffuser stability monitor http://modis.gsfc.nasa.gov/

  11. Other Natural Events that requiresub-daily Monitoring & Tracking Dust Cloud October 23, 2002 10:05 am (Terra) 1:35 pm (Aqua)

  12. Other Natural Events that Require Daily Monitoring & Tracking Typhoon Silaku off Japan Sept. 4/2002 Phytoplankton Blooms Gulf of St. Vincent, Feb. 19, 2002

  13. Implementation Peter Dyce & Alan Marks CSIRO Land and Water

  14. Hotspot Locations are generated by combining information from several MODIS bands. HOTSPOT DETECTION

  15. ACRES Data Acquisition Facility Alice Springs HOTSPOT Linux server Data Transferredas a text file to Canberravia secure copy protocol Image Processing: • Conversion of signal to imagery • Geolocation. • Calibration. • Fire Product Processing • Fire Location point extraction Image Reception Image receivedby X-Band Receiver INFRASTRUCTURE…

  16. SDE-bu GIS database IMS-bu Map Server Web Server Map Making • Map Server receives requests from Web Server • Queries made • GIS Layers and Imagery combined to generate maps which are sent to the Web Server Incorporation into GIS • Data reformatted • Imported into Geodatabase • Database processes queries from the Map Server and datareturned. Web Map Serving • Web Server receives requests from clients (user browsers) • Requests Passed to the Map server • Maps served to the clients INFRASTRUCTURE… Canberra

  20. Web Maps are Dynamic. • Fire Locations are displayed in relation to other Geographic data • Maps are rendered and displayed on according to user interaction • Contextual layers can be added or removed. • Maps can be panned and zoomed. • Maps Layers are scale sensitive providing more information atlarge scaleswithout clutteringthe display at small scales.
