  1. GIS in Water Resource Term ProjectRiver Mapping Using Low Cost Small Unmanned Aerial Vehicle with Remote Sensing Platform Yiding Han Dept. of Electrical and Computer Engineering Utah State University E: yiding.h@aggiemail.usu.edu 12/02/2008

  2. Introduction • Background • Project Objects • Data Acquisition • Results • Conclusions GIS in Water Resource - Term Project Presentation

  3. What is UAV? • unpiloted aircraft • remote controlled • fly autonomously • pre-programmed flight plans • complex dynamic auto-navigation • military role • growing number of civil applications GIS in Water Resource - Term Project Presentation

  4. Why UAV? Safe Easy Low cost GIS in Water Resource - Term Project Presentation

  5. Our UAVs • Different sizes (air frames) • from 25 inches to 72 inches • Different payloads • GhostEye cameras: RGB/NIR cameras • Video cameras • Thermal Infrared Camera • Different missions • River Mapping • … GIS in Water Resource - Term Project Presentation

  6. River Mapping Mission • River path might change seasonally • Current remote sensing systems • Hard to use • Not accessible to anyone • High cost • A better tool is needed GIS in Water Resource - Term Project Presentation

  7. UAVs River Mapping Schedule • Design flight plan • Drive to launch site • Launch the plane • Wait • Land the plane • Take the images back for further processing GIS in Water Resource - Term Project Presentation

  8. Design the flight plan GIS in Water Resource - Term Project Presentation

  9. Contd... • Problems • Data may have error • Tedious • Elevation change is hard to input • Time consuming • …… • Use GIS to help us generate the waypoints GIS in Water Resource - Term Project Presentation

  10. Data source • DEM Data • USGS • http://seamless.usgs.gov • Riverflow of Bear River • NHDPlus • http://www.horizon-systems.com/NHDPlus/ GIS in Water Resource - Term Project Presentation

  11. Flight path given by ArcGIS GIS in Water Resource - Term Project Presentation

  12. Generate the waypoints • Waypoints are saved in an xml file GIS in Water Resource - Term Project Presentation

  13. Outcome in GCS GIS in Water Resource - Term Project Presentation

  14. Mosaic of pictures GIS in Water Resource - Term Project Presentation

  15. Good Mosaic GIS in Water Resource - Term Project Presentation

  16. Bad Mosaic GIS in Water Resource - Term Project Presentation

  17. Conclusions • With the help of GIS, it is a lot easier and faster to make complicated flight plan. • The generated waypoints are more accurate. • With 3D coordinate waypoints, UAVs can fly above more complicated terrain. GIS in Water Resource - Term Project Presentation
