Release of new version of database retrieval program
Today NGS is implementing a new
datasheet retrieval program to facilitate publication of data from the
Southern Louisiana Height Modernization project completed after
Hurricane Katrina in conjunction with FEMA post hurricane recovery
efforts. There should be no change in the datasheets
published for other parts of the country, but special circumstances
caused by subsidence in the southern Louisiana region require some
changes to the publication of certain stations there. In
2004, a similar project was published in the NGS Database and NAVD 88
orthometric height data was made available in a defined subsidence
region of southern Louisiana for stations in this project.
Heights for other bench marks in the region were suppressed to prevent
use of the outdated data with the new values. The project
completed in 2006 covers a geographic area that extends further north
in Louisiana, and densifies the vertical network by more than 230
additional bench marks.
Please direct questions concerning the project or data in southern
Louisiana to the State
Geodetic Advisor or the Height
Modernization
Manager.
