As this is an on-going project, there will be constant updates. The public can help in many ways, especially with providing up to date soundings. If you have a GPS and a depth transducer that are connected and communicate (usually via NMEA) then you can help!
If you want to help or contribute simply e-mail us by clicking here and let us know what equipment you have and we'll let you know how to go about it. It's really very simple, and you'll have the satisfaction of seeing your own data included in the chart.
