Detailed report on verification of buoy locations using GPS readings overlaid on nautical charts, updating dock shapes, and identifying new structures along Kelley's Island.
E N D
Co-op Charting • This represents the work of Akron Power Squadron Aug 25, 2007 • To verify the location of buoys, we brought the boat alongside the buoy, keeping the buoy to port. GPS readings from Garmin-GPS-72 were used. • The GPS reading has been overlayed on the chart in the attached pages • In some cases, when we couldn’t get alongside the aid or feature, we took a bearing and noted it on our write-up • Pictures from air are from Windows Local Live, http://local.live.com/ • Our chart was 14844. • Changes to the chart as printed are: • Shape of dock by old Coast Guard Station • Several new docks on north side of Kelley’s Island that do not appear on chart. P-1 – overview of attachment
