Comprehensive Data Capture and Analysis of Mataniko River and Surrounding Areas

This project involved a detailed data capture and analysis of the Mataniko River and adjacent sites, such as the April Ridge and local water dams, using UAV technology. The team executed meticulous flight planning and data extraction, including geometric correction, geo-referencing, and image processing for high-resolution documentation. The results, comprising image data of flood extents, dam surveys, and mining site assessments, are now stored in the SPC office for further interpretation and analysis. Comprehensive documentation highlights potential chemical hazards in the resettlement areas.

  1. Assistance GIS&RS Combined SPC-SOPAC & Solomon Island Team

  2. Targets of Data Capture • Mataniko river bed • April ridge • Water dam • Mining site

  3. UAV Image Recording • Flight planning • Copying data to UAV • Flying • Data extraction

  4. Image Processing • Image stitching • Geo-referencing • Geometric correction

  5. Image Data Storage& Exchange • New image data and interpretation -> SPC Office • Image interpretation to SPC-SOPAC • External hard drive as buffer

  6. Data Storage

  7. Mataniko River Image

  8. Image Interpretation • Analysis QuickBird data 2008 • Delineation flood extent 2014 Team was working parallel to image data capture

  9. Mataniko River Mapping

  10. Mapping • One team for recording • One team for mapping • Results after 4 days

  12. Lake with Chemicals

  13. Problem Dam Overflow

  14. Left Over Mine Camp • Possibly left over explosives • Definitely dangerous chemicals • Documentation required

  15. Very High Resolution Images Through Slow Speed

  16. Results: • Image data of Mataniko river recorded & available • Mataniko flooding area available • DSM recorded for dam • Image data April ridge processed • Contour lines of April ridge • Image documentation of mine site • External drive in SPC office • Image database
