Well, raw topographical data for the entire world at a 5 minute
resolution may be obtained in a variety of binary and ascii formats from
either the TOPO5 or TerrainBase 5 minute grids at

Some useful terrain data might also be at this USGS site:

Oh, and the variable resolution DBDB-V bathymetry database may be found
at  Look under the "Data Warehouse" link. 
This database will return real and/or interpolated depths at up to half
minute intervals.  It is only bathymetric data though, no surface
information. Still, it might be useful for you.
