Future Applications of National Hydrography Dataset (NHD)

Explore the potential uses of NHD including zooming to location, printing maps, basin boundary evaluation, and more advanced analysis functionalities for drainage area. Learn about CNMS and its goal to create a national flooding inventory database and serve FEMA's mapping needs management. Coordinated Needs Management Strategy involves geospatial database of mapping needs including all streams draining larger than 1 sq. mi. Stay informed about the latest in stream mileage and Flood Estimation Handbook (FEH).

  4. StreamStats Functionality • Zoom to street address, geographic name, or coordinates • Display of default base data layers for selected map scale ranges • Evaluate basin boundaries in the map frame • Print maps shown in the map frame • Download basin boundary and other map data • More analysis functionality (drainage-area ratio estimates, weighted estimates, etc.) is planned

  5. What is CNMS? • Goal: • Produce a National inventory database of flooding sources corresponding to our mapping inventory that: • Tracks program status on NVUE. • Informs map planning production decisions - References mapped flooding sources as valid or as having an unmet need. • Serve as FEMA’s mapping needs management system - MNUSS will be sunset. • Document accomplishments - Resolution date of existing mapping needs will be captured.

  6. Coordinated Needs Management Strategy • Geospatial database of mapping needs • Includes all streams draining greater than 1 sq mi • Used for planning for future mapping efforts
