Summary
Abstract: The Elevation Derivatives for National Applications (EDNA) is a multi-layered
database derived from a version of the National Elevation Dataset (NED), which
has been hydrologically conditioned for improved hydrologic flow
representation. The seamless EDNA database provides 30 meters resolution raster
and vector data layers including:

-Aspect
-Contours
-Filled DEM
-Flow Accumulation
-Flow ... View entire text

Access Constraints Access to Ssalto/Duacs products

Ssalto/Duacs products use Jason-1, Envisat, GFO, ERS-1, ERS-2 and
Topex/Poseidon data. File format is NetCDF, but the system also delivers images
in Postscript format (only for gridded products).

Ssalto/Duacs system delivers global and specific regional products; combined
datasets are also provided for high precision ... View entire text
Use Constraints When using Ssalto/Duacs data (NRT or DT-(M)SLA and (M)ADT), please cite: "The
altimeter products were produced by Ssalto/Duacs and distributed by Aviso, with
support from Cnes".
