Introduction
Hydrography is the science of the measurement, description, and mapping of the surface waters of the earth.
The Hydrography Technical Working Group (Hydro TWG) focus is to enhance the digital representation of streams, lakes, canals and other surface water features as well as watersheds in the State of Idaho. The Hydro TWG facilitates contributions to national hydrography related datasets, as well as assists in coordination and development of standards for Idaho’s hydrography needs.
Formal stewardship is in place and improvements are incorporated from local sources via the USGS Markup Application. The Idaho Department of Water Resources (IDWR) is the Framework Steward.
Vision
To provide a forum to coordinate and facilitate creation of current and correct digital hydrography for Idaho that is useful at a local, state, regional and national level through updating of the Idaho Map (TIM) Framework Datasets recognized for the Hydrography Framework Data Theme elements.
Goals
- Facilitate contributions to national hydrography related datasets.
- Disseminate information on upcoming updates and changes to the national datasets and the tools for editing them.
- Share success stories from users who have solved real world problems using hydrography data.
- Prove a mechanism for edit review and conflict resolution in order to provide the most accurate assessment of hydrography in the state.
- Assist in coordination and development of standards for Idaho’s hydrography requirements as needed.
Framework Layers
Hydrography – National Hydrography Dataset
The National Hydrography Dataset (NHD) is recognized by the IGC-EC as the Framework Dataset for the Water Features Element of the Hydrography Framework Data Theme for Idaho.
Hydrography – Watershed Boundary Dataset
The Watershed Boundary Dataset (WBD) is recognized by the IGC-EC as the Framework Data set of the Watershed Element of the Hydrography Framework Data Theme for Idaho.
