Benefits of incorporating the WBD into the NHD Geodatabase  Take advantage of established and proven concepts in the NHD design to advance the WBD design  Take advantage of geodatabase technology  Improve interoperability between the two datasets  Allow the use of NHD GeoEdit to edit NHD and/or WBD

Benefits (cont’d)  Allow WBD edit transactions to be generated and input into the joint database  Allow the joint stewardship of NHD and WBD  Allow the joint management of both datasets  Allow the joint distribution of both datasets  With the completion of the WBD, the timing is excellent to carry out this integration

Geodatabase structure The NHD geodatabase will be subdivided into a NHD feature dataset and a WBD feature dataset The full complement of the WBD, plus new additions will be made to the WBD data design to help it integrate better with the NHD It is a multi-level design that organizes data to best facilitate relational functionality while conserving the design to boost efficiency House multiple datasets that can share characteristics House multiple feature classes that can also share characteristics Tables and relationships can also be housed by the geodatabase to facilitate the functionality

NHD WBD Integration   Spring 2008 USGS and NRCS agreed that the WBD database should be integrated with the NHD geodatabase   Summer 2008 An MOU was signed to that affect   Summer 2008 Geodatabase interagency design team was formed A series of teleconferences were held to outline: WBD user needs Outlined detailed design for WBD database Storage Retrieval Editing Metadata tracking..

Delivery: Once fully implemented the NHD and WBD will be jointly housed in Denver, and Denver will be the interface node for stewardship maintenance transactions The NRCS will house a replicate of this database for distribution only National Sites that customers will obtain NHD and/or WBD data through (1) The National Map, (2) the NRCS Data Gateway, and (3) a hydrography specific web site ( Users will have several options for downloading. This will include (1) NHD-WBD options, (2) areas of coverage, and (3) levels of hierarchy Stewardship of the WBD will be folded into the NHD stewardship program using a similar NHD technical and programmatic approach

Geodatabase Design  Incorporate current WBD attributes, as well as attribution needed for NHD integration Additional attribution will be added to improve functionality and interoperability Additional attribution will be added to improve functionality and interoperability  WBD will migrate from shapefile format to geodatabase format  WBD Metadata will be patterned after NHD, but a separate table is needed to account for WBD specifics  Recognize potential future improvements, enhancements, additions Coastal, 7 th and 8 th level, international, names, etc. Coastal, 7 th and 8 th level, international, names, etc.

Current WBD Attribution - line  Level (0-6)  Linesources  Metadata version

Current WBD Attribution - polygon  and 12-digit coding, as well as downstream coding for 10- and 12-digits  Naming at 10- and 12-digit  Size reported as acreage  State(s) that subbasin falls in  Type at 10- and 12-digit  Modifications at 10- and 12-digit  Non-contributing with acreage  GNIS # at 10- and 12-digits  Metadata version

NHD GeoEdit Tool  The WBD edit tool will be created and incorporated into the NHD GeoEdit Tool   The GeoEdit Tool will be used to jointly maintain WBD and NHD NHD currently has rules inside the tool, WBD will need these added Use of organization code to restrict access Managing attributes QA/QC Track metadata WBD will carry NHD Reach-code and Com-id (increased utilization of data)

Transaction process  Mimics NHD, except that……….. Transactions that arrive at the USGS will be handed off to USGS/NRCS reviewers to determine WBD compliance prior to acceptance Transactions that arrive at the USGS will be handed off to USGS/NRCS reviewers to determine WBD compliance prior to acceptance

Current WBD maintenance practices  Maintenance of the WBD using the NHD process will only be implemented once all processes, tools, functions, and databases are ready  Laura Davenport, NRCS will discuss the current WBD maintenance practices
