The Integration of Elevation and Hydrography Data
Track: Water Resources
Authors: Jeff Simley
The USGS is developing an integrated elevation-hydrography dataset that can better serve water science. The initiative addresses nine aspects of integration: The alignment of elevation and hydrography, Interoperability of features, Data model that links the elements, Synthesis to produce new data, Derivative characteristics, Program to jointly produce the DEM and NHD, Synchronization for temporal coincidence, Product to package the data, Delivery so the data can be accessed in unison.
