The Cooperative Charting 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 to USCG and local agencies.
  • 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 1 mile north of Marco Island  to Everglade City, about 20 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 provided in the following Excel Workbook: 

MISPS ATON Survey Data 2019-04-24.xlsx

Most of the data is from on-the-water surveys by MISPS members, but the file also contains data provided by United States Coast Guard Auxillary (USCGA) members and Collier County Costal Zone Management (CZM) employees.  The file can be viewed on-line, or downloaded and opened in Excel for access to sorting, filtering and other Excel features. More Info.

Data Visualization

Survey data and USCG Lightlist data can be visualized by downloading and opening the following file in Google Earth. Clicking on the link 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. More Info.

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. Clicking on a Light List icon shows the zone ID, full Light list name, and coordinates. Various subcategories of the data can be turned on or off by expanding the folders and checking or un-checking boxes in the Places panel on the left side of the Google Earth window. There are two categories of data that are not checked by default: "Zones" shows how ATONs are grouped by zone, and "RNC/NOAA_RNC" overlays NOAA chart 11430 (the slider below allows making it transparent). If the folder "MISPS Latest Survey & Lightlist" is moved from "Temporary Places" to "My Places", it will be there the next time you open Google Earth and the display will automatically update to the most recent information. 


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. More Info.
