Geodetic Advisor Aids U.S. Coast Guard
This week, the National Geodetic Survey's (NGS) Geodetic State Advisor for Florida is installing a survey marker at the U.S Coast Guard (USCG) station in Jacksonville, Florida. The marker will allow the Coast Guard to calibrate GPS systems used on their ships for more accurate geo-referencing of coastal operations. Following the installation, four hours of data gathering is required to establish the position of the survey mark relative to the National Spatial Reference System. The collected data will then be submitted to NGS' Online Positioning User Service (OPUS). Following this, NGS will provide positions to the USCG using NGS processing software. The new marker, installed at the request of the USCG, will result in more accurate positions for all Coast Guard at-sea work, including rescue operations. For more information, contact David Newcomer.
