This has ocean bathymetry and land elevations.
- Floating point binary version is probably the best.
Save it as a 16 bit integer, since the floating point values are
actually integers.
- 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.

and other less useful formats. If Geotiff is not present, MICRODEM via
GDAL can read the nc file. The current version 3 still has v2 in
the file names, but the data hole near Japan has been filled in. |

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. |
