  2. Wetlands Geodatabase • FWS Wetlands Mission • Cooperation • History of Wetlands Mapping • Techniques and Standards • Status of the Wetlands Geodatabase • Future Directions • Questions

  3. Service’s Wetlands Mission • The U.S. Fish and Wildlife Service is the principal Federal agency that provides information to the public on the extent and status of the Nation’s wetlands. • Under the Office of Management and Budget Circular A-16, revised August 19, 2002, responsibility to coordinate wetlandsdata related activities is assigned to the Department of Interior, U.S. Fish and Wildlife Service. 

  4. Service’s Wetlands Mission • FWS has maintained a wetlands mapping effort for over 30 years • National Wetlands Inventory • FWS wetland definition is the FGDC standard • Provides classification, location, and extent of wetlands and deepwater habitats; no attempt to define the proprietary limits or jurisdictional wetland boundaries of any Federal, State, or local agencies. • FWS Wetlands Geodatabase forms the framework for NSDI wetlands spatial data layer

  5. Agency Cooperation • USGS • CAPP-WRD • Technological Knowledge • GIS expertise • Wetland knowledge • Worked on prior Wetlands Status and Trends projects • ESRI • Database review • System Architecture Review

  6. Historic NWI wetlands data • Data inconsistency: different map projections and datums; inconsistent data fields. • Static system (data archive). • Inefficient storage and distribution. • Insufficient documentation. • File based access. • Technology outdated.

  7. FWS Wetlands Geodatabase • Standardized data storage • Improved quality of mapping process • Integration of supporting information • Improved geographic analyses: faster, more efficient, larger data extent • Improved public interface • Improved data distribution • Standardized data updates and additions • Seamless storage of data improves reliability, backup, and archiving

  8. Service’s Wetland Standards • Cowardin et al. (1979) wetlands classification • 1:24,000 • reconnaissance level topical overlay • Digital spatial data product • Preferably shapefiles or geodatabases • Albers Equal Area Projection • Topology • QAQC Verification Tools • FGDC metadata and metadata footprint

  9. Cowardin Wetland Classification

  10. Cowardin Wetland Classification

  11. Cowardin Wetland Classification • PUBGx = P – UB – G – x • Palustrine, Unconsolidated Bottom, Intermittently Exposed, Excavated • L2AB4Hh = L – 2 – AB – 4 – H – h • Lacustrine, Littoral, Aquatic Bed, Floating Vascular, Permanently Flooded, Impounded • PFO4/EM1Ad = P – FO – 4 / EM – 1 – A – d • Palustrine, Forested, Needle-leaved Evergreen, with Emergent, Persistent, both are Temporarily Flooded, Partially drained/ditched

  26. FWS Wetlands Mapper

  27. FWS Wetlands Mapper

  28. FWS Wetlands Mapper • Registered with Geospatial one-stop • Registered with the Conservation Portal • WMS layers served on The National Map • FY06 statistics • 43.6 million website requests • 1.7 million map requests • 446 GB data transferred • 1044 Data extraction Requests (6 months)

  29. Wetlands GeodatabaseFuture Directions • New Layers • Restorable Wetlands • Hydric Soil identified wetlands • LLWW (Landscape Position, Landform, Water Flow Path) • Improved Database Intelligence • Parsed codes and descriptions • Plant List • Significant Wetland Areas • Analysis • Serving of Data Models and ArcServer capabilities • External Data Contributions
