  1. NGS and National Height Modernization Program Update CSRC Coordinating Council Meeting Fall, 2011 La Jolla, CA via webinar

  2. STRATEGY • Advance science, models, tools, and education in order to: • Achieve Ten-year Plan Objectives • Achieve National Height Modernization Program (NHMP) goals • Transition to new geometric and geopotential datums (c. 2022)

  3. NGS/NHMP Activities Science: NHMP supported projects to enhance vertical component of NSRS. MYCS – release of Multi-Year CORS Solution NA 2011 – adjust passive control for consistency with MYCS GEOID12

  4. NHMP ACCOMPLISHMENTS Science: NHMP supported projects to enhance vertical component of NSRS. GRAV-D fieldwork and data processing to support a 1 cm geoid and the new geopotential datum Pilot Project in North Carolina to produce a new set of instructions for FEMA floodplain mapping based on access to the new datums Texas Geoid Slope Validation Survey engaging a variety of testing methods to address achievable accuracy of a gravimetric geoid model International Great Lakes Datum (IGLD) fieldwork and data processing completed to update the IGLD, benefitting US-Canada boundary region

  5. NHMP ACCOMPLISHMENTS Models and tools: NHMP supported many recent NGS products including. HTDP development in partnership with Scripps and University of Alaska, Fairbanks – also working on vertical (e.h.) component- VTDP VTDP development including repeat surveys in Southern Louisiana and subsidence monitoring in Harris-Galveston Subsidence District Transformation tool between epochs after National Adjustment of 2011 – studying the need for it

  6. NHMP ACCOMPLISHMENTS Education: NHMP continue to support education and outreach. Monthly teleconferences, now with guest speakers LiDAR workshop and Partner Meeting in August 2011 ACSM / Survey Summit / ESRI User Conference in July 2012 Updating NGS HMP web site

  7. NHMP FUTURE PLANS • Developing National Height Modernization Plan (NHMP) • Updating Height Modernization Guidelines, NGS 58 / NGS 59 • Infrastructure gap (e.g. CORS) analysis • Modernize NGS geodetic control datasheets

  8. Questions Renee Shields Height Modernization Manager 301-713-3231, x116 Renee.Shields@noaa.gov
