Selective Drainage Toolbox—Lidar-based Elevation Rasters

National Hydrography Advisory Call:

This episode of the features speakers Ryan Thompson (Dakota Water Science Center – Huron, South Dakota) and Curtis Price (Dakota Water Science Center – Rapid City, South Dakota). The presentation is an overview of the Selective Drainage Toolbox. The discussion focuses on a study area in South Dakota that identified the need for the tools and the methodology that went into development of the tools. Q & A follows with both presenters.

Hydrography for the Nation:

High-quality hydrography data are critical to a broad range of government and private applications. Resource management, infrastructure planning, environmental monitoring, fisheries management, and disaster mitigation all depend on up-to-date, accurate, and high-quality hydrographic data. The U.S. Geological Survey National Geospatial Program National Hydrography Advisory Call has initiated a series of virtual seminars to highlight the uses of hydrographic data. These presentations are intended to share success stories from users who have solved real world problems using hydrography data, provide information about the National Hydrography Dataset and related products. The USGS manages surface water and hydrologic unit mapping for the Nation as geospatial datasets. These include the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), and NHDPlus High Resolution (NHDPlus HR). Hydrography data are integral to a myriad of mission critical activities undertaken and managed by government entities (Federal, State, regional, county, local, Tribal), nonprofit organizations, and private companies.
