Monthly Height Modernization Coordination Meeting
The Height Modernization manager holds monthly coordination meetings to provide a forum for discussing Height Modernization activities. Meetings are held on the second Thursday of every month, from 2:00-3:30 p.m. East Coast time. Interested parties are provided a conference call number to attend.
Each month, speakers are invited to give presentations or facilitate discussions on various topics related to Height Modernization. The presentations add value to the meeting, educate constituents about NGS activities, and gather feedback from users of NGS projects. Please plan to attend meetings with presentations particularly relevant to your work or interests.

Arizona Statewide Vertical Adjustment
Michael Dennis, National Geodetic Survey
A vertical adjustment was performed in Arizona, which yielded new GPS-derived orthometric heights throughout the state. The results and significance of the adjustment will be discussed, including a possible nationwide vertical adjustment using National Adjustment of 2011 ellipsoid
heights and the next hybrid geoid model, GEOID12.

U.S. Geological Survey Stream Gages and Vertical Datums
Jim Kolva, U.S. Geological Survey
Renee Shields, National Geodetic Survey
USGS is working with NOAA on an effort to update their stream gage database to standardize the vertical datum used as the reference to NAVD 88. NGS and USGS are interested in partnering with interested parties across the country to work on this effort.

Geoid Slope Validation Survey of 2011 (GSVS11)
Dru Smith, National Geodetic Survey
NGS completed an extensive survey of a 300 km north-south line from Austin to Corpus Christi, Texas to validate an important component of the latest gravity surface model. Preliminary results show significant benefit is being realized from the GRAV-D survey project.

Updates to the NGS Datasheet Format
Burt Smith, National Geodetic Survey
NGS has developed several modifications to the NGS datasheet – the primary method for accessing the passive control network of the National Spatial Reference System (NSRS). These changes will provide more information about published positions and better serve the needs of our
stakeholders.
Presentation was a live demonstration; no powerpoint available.

National Enhanced Elevation Assessment (NEEA)
Gregory Snyder, U.S. Geological Survey
David Maune, Dewberry
NEEA was completed in December 2011, and USGS is coordinating a program implementation and funding strategy with other National Digital Elevation Program agencies. This presentation will focus on the key findings, program recommendations and next steps for NEEA.

The next NGS 10 year plan
Dru Smith, National Geodetic Survey
The current NGS 10 year covers the years 2008 to 2018. It outlines an aggressive strategy for change and modernization, but it is already getting dated. Priorities, directions and resources have changed since 2008; sometimes in significant ways. For this reason, NGS plans to
create a new ten year plan (2013-2023). The new plan should have
many improvements over the existing plan.

GPS and Flood Certificates
Gary Thompson, North Carolina Geodetic Survey
Scott Lokken, National Geodetic Survey
A key component of the National Flood Insurance Program is the completion of Elevation Certificates. With an accurate geoid model, GNSS can be used to perform surveys to measure heights to FEMA standards. This presentation will describe the methods recommended
to surveyors in North Carolina for determining elevations to complete
Elevation Certificates.
