National Height Modernization National Partner Meeting Silver Spring, MD August 19, 2011
In Memorium Dr. Roy K. Dokka 1951 - 2011
National Height Modernization Program Update National Height Modernization Partner Meeting Silver Spring, MD August 19, 2011
STRATEGY • Advance science, models, tools, and education in order to: • Achieve National Height Modernization Program (NHMP) goals • Transition to new geopotential datum* (c. 2022) • *New geopotential datum is a priority of NGS Ten Year Plan
NHMP GOALS • Access to accurate, reliable heights nationally • Consistent standards across the nation • Data, technology, and tools that yield consistent results regardless of terrain and circumstances • “Maintain-able” system and process
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
NHMP ACCOMPLISHMENTS Models and tools: NHMP supported many recent NGS products including. Geoid09 release and Geoid12 development HTDP development in partnership with Scripps and University of Alaska Fairbanks 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
NHMP ACCOMPLISHMENTS Education: NHMP continued to support education and outreach. Monthly teleconferences, now with guest speakers FIG Conference, Australia in April 2010 Federal Summit in May 2010 State conferences; 2009-2011 events in AK, CO, ID, IL, IN, LA, MD, MO, NB, NH, NJ, OH, OK, PA, TX, and UT ACSM / Survey Summit / ESRI User Conference in July 2011 LiDAR workshop and Partner Meeting in August 2011
NHMP FUTURE PLANS • Support of NGS projects (e.g. GRAV-D) and products (e.g. Geoid models, HTDP, and VTDP) will continue. • New initiatives may include: • Developing National Height Modernization Plan (NHMP) • Updating Height Modernization Guidelines, NGS 58 and NGS 59 • Infrastructure gap (e.g. CORS) analysis • Modernize NGS geodetic control datasheets
