Nautical Chart Corrections

Observing and reporting differences between charted information and that which is currently observable.

Coast Pilot Revisions

Examining those sections of the Coast Pilot covering your area and determine where changes should be made to reflect current reality.

Depth Surveys

Measuring position, depth, at various positions in the areas of interest.

Range Line Surveys

Similar to Depth Survery except measurements are position readings taken along tracks identified by Range Markers.

Aids to Navigation Inspections

This involves cruising around your favorite areas and observing the buoys and other markers. Items to check are: proper functioning of light and sound characteristics, ledgibility of identifying marks and that the ATONs are in proper position.

Field Guide and Summary sheets

A series of "Field Guide and Summary" sheets is available. These are intended to be printed back-to-back, laminated or put in page protectors and kept on your boat or other convenient place. When used on line, they contain live links to reference data and report forms.

Nearest Light - A program to find a USCG light list number quickly.

Nearest Light is a Windows application that finds the lights nearest to your present position, using the monthly Light List updates published by the United States Coast Guard. The full Light List is published in printed and PDF formats but the lights are listed in reference number order and follow the channels. This is not the ideal format for Cooperative Charting, where we are usually working from a GPS.

Nearest Light takes care of that problem by utilizing the Light List that is now published in XML form, and searching that list for all the lights in your current area, using a GPS receiver connected to your computer (or a manual position), sorting that list, and showing you all the lights nearest to your position while out on the water. The light list provides additional detail which is not noted on a chart. Discrepancies can be more accurately noted in real time and, when the chart does not match a light list entry that is a discrepancy that can be reported as a CCWEB nautical chart item.

When preparing for a CoCh survey, Nearest Light can be used to find all the lights in the likely survey area and then to print the resulting table for inclusion with the survey worksheets. This lets everyone have the relevant portion of the Light List on hand for reference while surveying, improving the accuracy of CoCh reports to CCWEB and the USCG.
