The draft 2007 hazard maps are significantly different from the 2002 maps in some areas of the United States. The new maps generally show decreases of about 10% across much of the central and eastern US for 0.2-s and 1.0-s spectral acceleration and peak horizontal ground acceleration for 2% probability of exceedance in 50 years (the hazard ...

Scale and Resolution and Reference Base Maps. This section identifies the standard operating scale that the park will strive to develop and maintain for their spatial database (i.e. 1:24,000, 1:100,000). Select and identify here an accurate base map or series of base maps to serve as a reference template.

Reference ellipsoid and geodetic datum of GPS, defined and maintained by the US Department of Defense. Current realizations of WGS 84 are considered identical to ITRF 2000 at the 2 cm level. See National Imagery and Mapping Agency (2000) for details, and Merrigan et al. (2002) for information on the most recent realization.

Geodetic leveling is performed at each CORS and the field observations are submitted to NGS as part of a Height Mod project. Two CORS sites in North Carolina were in the top fifteen (15) most downloaded sites in the US via User Friendly CORS (UFCORS). NCGS is performing a geodetic leveling project between Raleigh and New Bern.

The United States began geodetic surveys later than most of the world's major countries, yet its achievements in this scientific area are immense and unequaled elsewhere. Most of the work was done by a single agency that began as the Survey of the Coast in 1807, identified as the Coast Survey in 1836,renamed the Coast and Geodetic Survey in ...
