Hydrography Community Calls
USGS sponsors the monthly Hydrography Community Call. Our focus is on hydrographic data, projects, research, and ideas that relate to the USGS Hydrography Program. Presenters have included scientists, data stewards, GIS analysts, engineers, educators - people applying, analyzing, or generating hydrographic data for the nation. Calls are open to everyone and we are always looking for presenters.
Contact us with any questions about signing up for future Hydrography Community Calls.
Our videos are available on the USGS Youtube channel and also below.
