  1. Remote Sensing Demand Pacific Island Countries Wolf Forstreuter Pacific Islands GIS&RS User Conference 2011

  2. History • 1991 forest inventory Fiji • 1998 GIS backdrops for utilities • 2000 coastal change detection in Tonga • 2006 coconut resource mapping • Today multiple utilisation of space born image data

  3. Image Utilisation • GIS backdrop as map replacement mainly Pacific utilities • Forest mapping (REDD+) • Disaster risk management • Land cover mapping of low lying islands (coconut resource) • Maritime boundary determination • Agricultural mapping (food security)

  4. Image Utilisation • History of island movements • Shallow water bathymetry / habitat mapping of near shore area • House mapping population census • Fast mapping of flooded areas • Shipping vessel detection • DTM for watershed management, airport security, island movement, flooding risk maps, orthocorrection of image data • Wind and current for search and rescue

  5. Disaster Risk Management • 400,000 roofs are mapped • For US$ 36,000 image data was purchased last year • Requirements: (A) VHR Data, detail of features recognisable

  6. Land Cover Mapping of Low Lying Islands • Most islands of Kiribati are mapped at 1:5,000 scale level • Coconut palms are counted for ¾ of the islands • Change detection at 1:5,000 performed for 4 islands • Requirements: VHR Data, texture information for coconut palm counting, bundle data preferrable

  7. Maritime Boundaries • For US$ 88,000 image data was purchased last year • Requirements: (A) VHR Data, detail of features recognisable, (B) high geo-accuracy

  8. Agricultural Mapping for Food Security • Currently mapping at 1:50,000 scale (first time) • US funded project will support mapping in FJ, KI, VU, WS, SB • Requirements: a) multi-spectral information including near infrared b) VHR image data (coconut)

  9. Documentation of Island Movements • No new image data purchased but utilisation of available data is ongoing • Requirements: VHR Data, details for reference image points 1968 2000

  10. Shallow Water Bathymetry and Habitat Mapping of near Shore Area • Requirements: 1:25,000 level resolution, multi-spectral information including blue and green bands

  11. Roof Mapping Population Census • For US$ 27,000 image data was purchased last year • Requirements: VHR Data, house counting at 1:5,000 scale level

  12. Fast Mapping of Flooding • Applied only two times • Method developed and available • Requirements: (A) penetration of cloud cover, (B) VHR image data, (C) fast data recording and delivery (D) clear separation of water and rest (E) reference images for geometric correction

  13. Fishing Vessels Monitoring

  14. Shipping Vessel Detection • Cross check of vessel monitoring system • Transport monitoring • Requirements: (A) VHR Data, (B) recording day, night and all weather situations, (C) fast data delivery, (D) capture of vessel shape, speed and material

  15. High Resolution DSM • Low lying areas, flood risk maps • Water catchment monitoring • Island movement • Airport security • Orthocorrection of image data • Requirements: High resolution stereo images, space borne radar data, LiDAR data or …
