Polder Vertical Datum Reports

Purpose:
These Polder Vertical Datum Reports contain detailed information about certain National Spatial Reference System (NSRS) permanent bench marks established by the National Geodetic Survey (NGS).  These permanent bench marks are approved for use by USACE-MVN-ED as vertical project control for all designs, plans and specifications for USACE-MVN projects that lie within the extent of a given polder.  This report also contains information (when available) on tide gauges within or near the Polder and their associated geodetic/tidal datum relationships.

Expiration Date:
Due to regional subsidence and global sea-level rise, the published elevations of the referenced benchmarks and the published tidal datum values at the referenced gauges (as well as the geodetic/tidal datum relationships computed there from) are time-dependant and subject to change. Therefore, the information contained in these reports shall be updated on a regular basis  and/or as new information becomes available.
