With the completion of the WBD, the With the completion of the WBD, the timing is timing is excellentexcellent to carry out this integration to carry out this integration
Geodatabase structureGeodatabase 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 IntegrationNHD 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
