This program is not related to the cooperative agreement between USPS and NOS for the updating of nautical charts and any credits awarded in this program do not apply to the nautical charting program.

Geodetic marks are highly accurate reference points established on the surface of the earth by local, state, and national agencies. Maintenance and preservation of these marks is of utmost importance to users of the net and to the National Geodetic Survey (NGS), recognizing that many valuable geodetic marks are destroyed by construction, new roads, erosion, or for other causes. Our job is to locate each of these marks and report their condition together with any change in the directions needed to locate them.

There are basically two types of marks, horizontal reference and vertical reference. Although the advances in GPS technology have made the horizontal reference marks less of a necessity in surveying, GPS cannot measure elevations accuracy so the vertical reference marks are still necessary for accurate surveying.

Normally, geodetic marks are round bronze disc, roughly 3 inches in diameter, firmly imbedded in concrete, bedrock or on a long rod driven into the ground.

The objective of this cooperative charting geodetic mark recovery program is to locate and identify these marks and to report on their condition as Good, Poor, Not Found, or Destroyed.

This is a valuable public service and, at the same time an opportunity for Squadron members to get together for a fun off the water activity.

General Requirements:
  • A mark recovery may not be submitted within 24 months of the last recovery unless there is a change of status from “not found” to “found”.
  • A mark may not be reported as “Not Found” if the previous report was “Not Found” or “Destroyed”.
  • All required fields must be completed on the submittal form.
  • Reports must be submitted within 30 days of the investigation.
