The Cooperative Charting Program of the United States Power Squadrons is conducted in close coordination with the National Oceanic and Atmospheric Administration.  The Cooperative Charting Program has been recognized as one of the most effective user-participation program in all of the Federal services. The Program is a major public service of USPS. Within this program, USPS Members:

  • Supply information to USCG and NOAA leading to corrections to nautical charts, small craft charts and Coast Pilot publications.
  • Supply data on depth surveys, range status, tidal current surveys and geodetic marks.
  • Inspect Aids To Navigation to identify and report damaged or misplaced Aids.
  • Focus on specific navigation area through the Adopt-A-Chart subprogram. 

The Marco Island Sail and Power Squadron Coop Charting program is currently concentrating on inspections of Aids to Navigation (ATONs) in the region of our adopted chart.  Our Squadron has adopted the portion of Chart 11430 that is south of Lat 25 deg 59.5 min N. This region extends from a point about half way between Marco Island and Naples to Lostman's River, about 34 nautical miles SE of Marco Island.  We check the condition and locations of ATONs and report discrepancies to the appropriate government organizations.

 For purposes of assigning responsibilities and identifying ATONs, zones have been defined as shown below and, with more detail in Zone_Maps.pdf

Survey Data

MISPS survey data and corresponding Lightlist data is summarized in the following Excel Workbook: 

MISPS ATON Survey Data.xlsx

The workbook can be viewed on-line or downloaded and opened in Excel.

It also has a form and instructions for on-water collection of survey data.


Data Visualization

Survey data and USCG Lightlist data can be visualized by downloading and opening the following file in Google Earth. Clicking on the ling should download it to your default download directory.  If you have Google Earth installed on your computer, clicking the downloaded file should open it in Google Earth.

MISPS Survey and Lightlist for Google Earth.kmz

Google Earth is a free program that allows plotting of the data on a satellite photo of the area.

In Google Earth, a key defining the various icons is visible in a white square to the west of Marco Island.  Clicking on a survey icon brings up a balloon showing zone ID,  date of last survey, condition reported in the last survey, and coordinates.  If there is no condition info, the aid was in reasonably good condition at that time.  By clicking on a Light List icon you see the zone ID, full Light list name, and coordinates. Various subcategories of the data can be turned on or off by checking or un-checking boxes in the Places panel on the left side of the Google Earth window.



Photos of ATONs, organized by Zone ID and survey date

To read folder names use List view rather than Grid view (icon at upper right in the Google Drive window).  Some photos are in folders and others are in PDF documents.  The photo folders are best viewed in Grid view, where thumbnails of the photos are visible.
