GIS Expo 2014: Hawaiian Islands Orthoimagery Update

  1. 1. Hawaiian Islands Orthoimagery Update HIGICC, Data Discovery March 14th, 2014 Anthony J. Kimmet Acting National Imagery Leader USDA-NRCS-National Geospatial Center of Excellence 501 Felix, Bldg. 23 Fort Worth, Texas 76115 (817)-509-3434 (Office)
  2. 2. HIGICC Topics • Hawaii Orthoimagery • Future Acquisitions • Special Acquisitions Pacific Basin Orthoimagery information was presented at the PRiMO conference on Wednesday, March 12th. If you would like a copy of this presentation please contact Tony Kimmet (tony.kimmet@ftw.usda.gov)
  3. 3. Hawaii Orthoimagery Availability 1997 - 2014 Camera/Sensor Resolution Islands Covered Years Special Project Areas - Aerial 1 Meter All / 70% 1997-2002 No - Aerial 1 Ft GSD Oahu 2005, 2008 No - Satellite/DG-QB2 .6 Meter All / 100% 2003-2008 No - Satellite/DG-WV2 .5 Meter All / 100% 2009-2012 Yes: Molokai, Maui, Lanai
  4. 4. • Version 2 of Orthoimagery for Hawaii is complete • Data distribution is via two portable discs, 3 TB each disc • Hawaii Island and Kahoolawe were updated and released as “Version 2, Release 2”. Hawaiian Islands Status of DG-WV2 March, 2014 Version 2, Disc 1 Version 2, Disc 2
  5. 5. Hawaii Island Orthoimagery Mosaics Release 1 (March, 2013) Release 2 (July, 2013)
  6. 6. •USDA-NRCS-National Geospatial Center of Excellence (NGCE) updated the Hawaii Island DigitalGlobe WorldView-2 (DG-WV2) Release 1 mosaic which was distributed in March, 2013. •Hawaii Island Orthoimagery Mosaic , Release 2 corrects some issues with Imagery distortion in northwest area of Hawaii Island near the city area of Waimea along with a few other noticeable anomalies. •After distribution of Release 1 mosaic, imagery distortion was discovered in the Waimea area if the scale of Imagery was viewed at 1:3,000 scale or less. The NGCE decided to correct this issue and a few other correctable issues in the northwest area. •Hawaii Island, Release 2 does not contain any new imagery but the existing scenes were enhanced and corrected. The following shows some of the corrections that were applied. Hawaii Island, Orthoimagery Mosaic, November 2013, Release 2
  7. 7. DG-WV2 Imagery outlined in red were reprocessed to correct known anomalies. The following shows what the corrections are for the areas listed in the map. Release 2 2
  8. 8. Hawaii Island, Orthoimagery Mosaic, March 2013, Release 1 Notice that the imagery at a scale of 1:8,000 looks relatively clear of any distortion Waimea, Hawaii
  9. 9. Hawaii Island, Orthoimagery Mosaic, March 2013, Release 1 Imagery at a scale of 1:2,000 or less shows most objects twice with a slight displacement. Waimea, Hawaii
  10. 10. Hawaii Island Orthoimagery Mosaics Waimea Area Release 1 (March, 2013) Release 2 (July, 2013)
  11. 11. Hawaii Island Orthoimagery Mosaics Waikoloa Area (NW Hawaii) Release 1 (March, 2013) Release 2 (July, 2013) Three different DG-WV2 scenes converged in the city area. #1 #2 #3
  12. 12. Hawaii Island Orthoimagery Mosaics Halaula Area (NW Hawaii) Version 1 (March, 2013) Version 2 (July, 2013) Cloud Patch Window Eliminated Scene cutline moved from this orchard
  13. 13. Hawaii Island Orthoimagery Mosaic, Release 2 PDF Files Created for Hawaii GIS Community
  14. 14. Hawaii Orthoimagery, Release 2, November 2013 After researching this issue, the NGCE discovered the following on the Imagery distortion issue for the Waimea area. •The NGCE completed a mosaic of Hawaii Island utilizing one version, or the best available DG-WV2 data for most areas of Hawaii Island. •The NGCE re-processed the Hawaii Mosaic many times to correct the distortion issue. Other know ammonias were also cleared up in this reprocessing. •Release 2 was distributed to a few sites in Hawaii for evaluation in August, 2013.
  15. 15. Majority of WV2 Orthoimagery Smears are located in this area
  16. 16. Know issues with Hawaii DG-WV2 Orthoimagery Mosaic, Release 2 - Waipio Valley in North West Hawaii Island has several Orthoimagery anomalies or smears/stretched at or near the coastline. - Selective areas of Waipio Valley has extreme terrain relief. A picture from the following website illustrates the issue. http://www.gohawaii.com/big-island/regions-neighborhoods/hamakua-coast/waipio-valley-lookout Terrain with high relief is difficult for a satellite to capture successfully
  17. 17. Example of Imagery Smear in Waipio Valley
  18. 18. 2002 - 3 Bands, 1 Meter GSD - Collected 1997- 2002 - 80% of Island collected USDA-NRCS-NGCE Hawaii Island High Priority Areas New Orthoimagery 2009 - 4 Bands, .6 Meter GSD - Collected 2003-20008 - 100% of Island collected Issues: - Clouds - Imagery Smears - Age of Imagery - Hawaii Mosaic will likely receive incremental changes every 6-12 months.
  19. 19. Hawaii Island – Potential Upgrade Areas
  20. 20. DigitalGlobe WV2 Hilo, Hawaii March 7th, 2014
  21. 21. Kahoolawe, DG-WV2 Release 1 The original DigitalGlobe WorldView-2 (DG-WV2) data received for Kahoolawe, Hawaii in 2010 was found not to overlay well with the previous USDA-NRCS-NGCE released QB-2 dataset (2005).
  22. 22. Kahoolawe, DG-WV2 Release 2 • The NRCS-NGCE in 2013 acquired several new versions of DG-WV2 for Kahoolawe. • After testing 3 new versions of WV-2, the NGCE determined that none of the new versions aligned well with the previously released QB-2 datasets. After reviewing the accuracy test results, the NGCE decided to test rectify a version of WV-2 called Kahoolawe, WV-2, Version 4. • Version 4 appears to be the most viable version because of the following. - Relatively low off-NADIR Angle (12.99) - High Sun Angle for the majority of the island (72.12’) - Relatively low clouds for the majority of the island - Steep cliff areas in the south and east ends of the island were viewable since the NADIR and sun angle were favorable.
  23. 23. Kahoolawe, DG-WV2 Release 2 (Version 4) After processing the Imagery in ArcMap, the NGCE was able to reduce the error to below 10 meters for all areas.
  24. 24. Hawaii Orthoimagery DG-WV2 Acquisition Dates Kauai: 2010 Niihau: 2010 Oahu: 2010-2011 Maui: 2009-2010 Lanai: 2010-11 Molokai: 2009-2011 Kahoolawe, R1: 2010 Kahoolawe, R2: 2011-2012 Hawaii: 2009-2012 Alternate Versions of West Maui, West Molokai and Lanai are available
  25. 25. Sedimentation Studies WV-2, 2/24/2011 Coral Reef Inventory WV-2, 10/14/2011 USDA-NRCS-NGCE and USGS-Pacific Coastal and Marine Science Center Working together to collect best available satellite imagery for scientific use Lanai, Hawaii Different Uses for Satellite Imagery?
  26. 26. Tentative Launch in Late 2014 • USDA-NRCS released complete coverage of Hawaii and some of the Pacific Basin in WorldView-2 with 8 Multi-Spectral Bands • What is the PRiMO community reaction to this type of Orthoimagery? • WorldView-3 will collect 16 Multi-Spectral Bands. Can we justify the extra cost for the extra MS bands? Federal Government license is for 50 cm (.5 Meter) GSD. DG has applied for a 30 cm license (~ 1 feet) !
  27. 27. • USDA-FSA-APFO has issued contracts for Orthoimagery for Hawaii and Maui Counties with DigitalGlobe (WV2, 8 Bands, 8 Bits). Contract ended last fall. Waiting for results. • Oldest Orthoimagery is on Kauai, Maui and Eastern Hawaii Island. These islands/areas may be the highest priority for new acquisitions? • Correct smearing Orthoimagery issues in Northwest Hawaii Island? • HIGICC members need new Orthoimagery for a special project? • Funding exists to update some Orthoimagery in Hawaii. Emphasis may be where the best new Imagery is available. Future Hawaii Orthoimagery Updates?
  28. 28. USDA-NRCS/DOD-NGA need user feedback from the HIGICC on how satellite Imagery is benefitting your programs. Any maps, documentation would be appreciated! Any research on the usefulness of the WV-2 8 Multi-Spectral bands on Remote Sensing applications (i.e.. Vegetation Analysis, Coral Reef Inventory etc…) Imagery Information Requested by USDA-NRCS
