Cooperative Charting

 

DEPTH SURVEYS

A Depth Survey produces a series of soundings that can be overlaid on a Nautical Chart and used to verify or supplement charted depth information. A computer program called DEPTH WIZ is being tested by USPS and the results are being evaluated by NOS as a means of updating depth information for chart areas where it is not practical for NOAA survey ships to be used. If you have the equipment to perform Depth Surveys and to use the DEPTH WIZ program, this becomes a valuable addition to the Cooperative Charting Program. For more information on this program, see:
