We have had many reports from users stating our numbers are "spot on!" We strive for accuracy and appreciate feedback from users. When we have a correction to a site, we email this to our newsletter subscribers and we post it on the website GPS lists. If you have feedback on a site, please submit a Reef Report.
When we created our files we compared numbers between each individual counties lists and state records. Any discrepancies were researched to determine the most accurate coordinates. We work with both state and local stakeholders to ensure the accuracy of the coordinates we publish.
Of cause, we cannot guarantee each site will be at its exact location, many factors can contribute to a site's coordinates being off or even a site missing. Past and recent storms can move a structure or topple it, deterioration of site materials from wave action and salt water, structure collapses due to age or use - all these events and more not mentioned can impact the quality of a site.
