This has ocean bathymetry and land elevations.
- The floating point binary version is probably the best.
Save it as a 16 bit integer, since the floating point values are
actually integers.
- The GRD98 version has registration that is
misinterpreted by 1 degree in
longitude because of byte swapping issues in MICRODEM, so do not get that version.
- The Geotiff version is not registered, so you must
create a world file for it.

Version 3 now available at

Derived from models of plate spreading. There is a value about every 11 km.
There is no data on continental crust, and problematic regions of
oceanic crust. |
