Help us complete our data inventory!
The Bottom Mapping Working Group is focused on creating a comprehensive regional Great Lakes inventory of hi-resolution bathymetry and sonar products. In order to do this, we need your help! Please, let us know if you have a dataset you’d like to contribute or if you know of any available datasets we might have missed!
When we have completed the data inventory the results will be posted here! Until then current available resources are posted below!
