NGS News

  • NGS reports
  • NHMP status: Renee Shields
  • GRAV-D: Vicki Childers
  • Geoid: Dan Roman
  • The NGS 10-Year Plan: Questions and comments from teleconference attendees
  • Concern that NGS may not support a passive network or provide access through the current database
  • Concern that NGS does not plan to consult the user community, except for the folks at ACSM, about its plan to move to a new horizontal datum and a new vertical datum
  • Concern with NAD83 legislation in states if a new horizontal datum is adopted by NGS
  • Recommend that NGS study the need for a new horizontal datum and a new vertical datum

Status report from each state or territory

Prior to the meeting, the Height Mod representatives from each state/territory in the southeast region were asked to prepare a brief report on the Height Mod activities in their respective state/territory.

  • South Carolina: Lew Lapine and Matt Wellslager
  • Charleston County has 12 tide stations that NGS was not able to survey for the VDatum project. Although these stations did not contribute to VDatum, they can validate it.
  • SC has a dozen CORS that have been in the NGS queue for acceptance into the National CORS Network for 1 ½ years. When will NGS accept these CORS?
  • The RTN data sharing agreement between NC and SC is working well for our RTN users along the NC/SC border.
  • Tennessee: Jim Waters
  • TN has RTN data sharing agreements with AL, KY, and MO. We are negotiating an agreement with NC.
  • TN seems to get their CORS into the National CORS Network fairly quickly.
  • TN Base Mapping Program (TNBMP): Multi layered digital basemap (GIS and imagery) that will support the business functions of State and local government
  • North Carolina: Gary Thompson, Scott Lokken, and Jerry Nave
  • Height Mod Workshops at NCA&T State University:

-Jerry Nave of NCA&T stated that this year’s workshop will be held in August before school starts, rather than in September as had been done in previous years.

-He had made a CD of previous workshops and sent it to Ross Mackay of NGS, but it never arrived. So, he will resend it.

  • DFIRM maintenance plan/schedule
  • CORS and RTN

-NC has ~7 CORS that have been in queue at NGS for about a year.

-Upgrading CORS from GPS to GNSS.

-Using Twitter to inform RTN users of network problems.

  • Using HM to do subsidence studies.
  • NC will be collecting statewide imagery in 2010.
  • Building a geodetic control database with a link to each corresponding NGS datasheet, but will also store/distribute control data that will not be submitted to NGS.
  • GA, KY, PR, VA, and WV: No reps in attendance
