Transcript of "Hawaii Pacific GIS Conference 2012: Survey and Positioning - Now and Future of Geodesy in Hawaii for the GIS User"

  1. 1. Now & the Future of Geodesy in Hawaii for the GIS Users Edward E. Carlson Pacific Region Geodetic Advisor NOAA’s National Geodetic Survey
  2. 2. OutlineState of HawaiiVertical NetworkReal Time Reference NetworkNational Geodetic SurveyNational Adjustment of 2011Geometric Datum 2022NGS Tool Kit
  3. 3. Hawaii DOT Height Modernization Plans• Phase 1 – Digital Leveling - First Order Class II using digital levels• Phase 2 – Continuous Operating Reference Stations (CORS) and Real Time Network (RTN)• Phase 3 – LIDAR and Airborne Gravity (NGS)• Phase 4 – Research and Development• Phase 5 – Reference Center Note: Phase 1 and 2 have been funded through CIP

  13. 13. Molokai - Proposed Level Network
  14. 14. Estimated miles of leveling• Oahu – Estimate of 211 miles• Maui – Estimate of 251 miles• Kauai – Estimate of 128 miles• Big Island – Estimate of 410 miles Note: Data to be submitted to NGS to be included in National Spatial Reference System (NSRS)
  15. 15. Phase 2 – CORS & VRS
  16. 16. • GPS Receivers: – Current GNSS Receivers and Geodetic Antennas• Equipment: – Solar panels, backup batteries, battery enclosure box – Modem radio where no internet exist to provide a single base solution• Construction: – In Federal, State or County property where possible – Sites may change depending on site issues (high buildings, trees, transmission towers, mountains, etc.)• Servers – Central server with redundant server located in each county.
  17. 17. VRS Network• Oahu - 7 Stations• Maui - 8 Stations with a possible 9th station• Kauai – 6 Stations• Big Island – 9 StationsNOTE 1: Will level to as many VRS stationsNOTE 2: Include at least 20% in the National CORS network system
  18. 18. National Geodetic Survey Announces Better Positions and Improved Access to theNational Spatial Reference System The National Adjustment of 2011
  19. 19. Introducing… NAD 83(2011) epoch 2010.00• Multi-Year CORS Solution (MYCS) – Reprocessed all CORS GPS data Jan 1994-Apr 2011 – 2264 CORS & global stations – NAD 83 computed by transformation from IGS08• National Adjustment of 2011 (NA2011) – New adjustment of GNSS passive control – GNSS vectors tied (and constrained) to CORS NAD 83(2011) epoch 2010.00 – Approximately 80,000 stations and 400,000 GNSS vectors• Realization SAME for CORS and passive marks• This is NOT a new datum! (still NAD 83)
  20. 20. Why a new NAD 83 realization?• Previous NAD 83(CORS96) needed many improvements• NSRS improvements achieved with the MYCS include: – Consistent coordinates and velocities from combined solution – Aligned with most recent realization of global frame (IGS08) • IGS08 epoch 2005.0 (previous aligned at epoch 1997.0) • NAD 83 epoch 2010.0 (previous epochs of 2002.0 and 2003.0) – Major processing algorithm, modeling, metadata improvements – Absolute phase center antenna calibrations• Highly accurate and consistent CORS coordinates and velocities determined using Best Available Methods – Needed because CORS network is foundation of NSRS
  21. 21. Datum Differences NAD83(PACP00) – NAD83(PA11) = 0.02m NAD83(PA11) - WGS84(ISG08) = 2.42m NAD83(PACP00) – WGS84(ITRF00) = 1.80m NAD83(PACP00) – NAD83(PA11) = 0.02m NAD83(PA11) - WGS84(ISG08) = 2.44m NAD83(PACP00) – WGS84(ITRF00) = 1.87m NAD83(PACP00) – NAD83(PA11) = 0.02m NAD83(PA11) - WGS84(ISG08) = 2.45m NAD83(PACP00) – WGS84(ITRF00) = 1.88m Hawaiian NAD83(PACP00) – NAD83(PA11) = 0.02m Islands NAD83(PA11) - WGS84(ISG08) = 2.47m NAD83(PACP00) – WGS84(ITRF00) = 1.91mNGA is doing a new definition of WGS84 in 2012
  22. 22. Datum Differences NAD83(MARP00) – NAD83(MA11) = 0.08m NAD83(MA11) - WGS84(ISG08) = 1.13m NAD83(MARP00) – WGS84(ITRF00) = 1.05m NAD83(PACP00) – NAD83(PA11) = 0.16m NAD83(PA11) - WGS84(ISG08) = 3.05m NAD83(PACP00) – WGS84(ITRF00) = 2.45m NAD83(MARP00) – NAD83(MA11) = 0.03m NAD83(MA11) - WGS84(ISG08) = 1.23m NAD83(MARP00) – WGS84(ITRF00) = 1.15m
