A Zonal Approach to National Height Modernization

Gilbert J. MitchellNational Geodetic SurveySilver Spring, MD


A zonal approach to national height modernization

  • National Spatial Reference System (NSRS)

  • NSRS is a consistent coordinate system that defines latitude, longitude, height, scale, gravity, and orientation for the entire U.S.

  • NSRS components include national shoreline, CORS, network of horizontal and vertical monuments and a set of models that describe dynamic geophysical processes that affect spatial measurements


A zonal approach to national height modernization

Height Modernization:

  • Height Modernization (HM) is the establishment of accurate, reliable heights using GPS technology in conjunction with traditional leveling, gravity, and modern remote sensing information


Noaa ngs partnerships

NOAA/NGS Partnerships

  • NGS’s mode of operation has migrated from agency staff doing the work to partnerships with state and local agencies, with NGS providing technical assistance

  • For some program areas, grant funds are made available to support federal share of costs


Zonal approach the general idea

Zonal Approach - the General Idea

  • NOAA administers HM through lead states and Spatial Reference Centers

  • Lead states and SRC:

    • Organize states in zone to address common issues and problems

    • Serve as link between NGS and individual states

    • Seek opportunities to provide education and outreach concerning HM program and its benefits


Height modernization zones

DRAFT - DO NOT DISTRIBUTE

Height Modernization Zones

APPROACH

  • Northeast

  • Mid Atlantic

  • Gulf of Mexico

  • Great Lakes

  • Upper Plains

  • Lower Plains

  • Southwest

  • Northwest

Leverage existing partnerships

Validate proposed HM zones

Evaluate needs and requirements

Identify activities to be accomplished

Solicit proposals for accomplishing activities

Establish partnerships – multiple partner

Promote “height technology transfer”

Active regions – expand program in new regions

DRAFT - DO NOT DISTRIBUTE


Zonal plan components

Zonal Plan Components

  • A National HM Steering Committee

  • Zonal pilot projects

  • HM forums in each zone

  • Regular zonal coordination meetings

  • Best practices workshops

  • Use of private sector resources (to conduct, manage, document, and evaluate HM projects, forums, and workshops)

  • Provide HM opportunities for all interested states

  • Provide R&D grants to state agencies and universities to support HM activities


Getting started steps for zonal leaders

Getting Started - Steps for Zonal Leaders

  • At this meeting we want to discuss with you:

    • Where we are with the Height Modernization Program

    • Where we want to be in 10 years

    • What we need to do to reach our mutual goals

  • In short, we want to hear your thoughts on how to best organize and carry out the ambitious goals of HM


Bringing new states into the hm program

Bringing New States into the HM Program

  • This is not an easy task, and we don’t have all of the answers, so your suggestions on how to accomplish the important goal of bringing new states on board are also very important


Support that noaa ngs will provide

Support that NOAA/NGS Will Provide

  • Technical assistance (standards & specifications)

  • Speakers for forums at the zone and state level

  • Administration of grant funds provided by Congress

  • Adjustment of HM data and providing access to it on NGS website
