Does anyone have experience using GPS devices to help map dive sites? They won't work underwater but I'm heading to a dive site (Twin Rocks, Anilao) where most or all will be visible from the surface. So the plan is to take bird-eye-view images from the surface while a GPS tracker records position, and then add the GPS information to the EXIF data based on time stamps. Software to do this already exists and GPS trackers cost as little as $50-100, some even being waterproof to 1m to protect against splashing.
Does anyone have experience on getting gps-tracking information or maps on the web with Google earth or other means. Or do I have to go to html5 and code something myself.
Does anyone have experience on getting depth information added to the exif data of the images.
This is all for a fun citizen-science project so the solutions have to be affordable. However, comments don't have to be limited to "cheap solutions" as others may have grant money or deeper pockets.
Thanks for any tips, Bart
