We prioritize areas to improved base around current plans for USGS 3DHP. Improvements within a HUC include reviewing all waterbodies to ensure they are still valid and spatially accurate. Where existing hydro-breaklines exist, we replace and/or add existing waterbodies with the newer geometry and append attributes were applicable. Currently the following HUCs have been updated: Hudson-Hoosic (02020003).<\/span><\/p> <\/p> NYS Hydrography Page: <\/span>https://gis.ny.gov/hydrography<\/span><\/a><\/p>
