tbase
(To be removed) Read 5-minute global terrain elevations from TerrainBase
tbase
will be removed in a future release. Use readgeoraster
instead.

Syntax
[Z,refvec] = tbase(scalefactor)
[Z,refvec] = tbase(scalefactor,latlim,lonlim)
Description
[Z,refvec] = tbase(scalefactor)
reads the data for
the entire world, reducing the resolution of the data by the specified scale factor. The result
is returned as a regular data grid and an associated three-element referencing vector.
[Z,refvec] = tbase(scalefactor,latlim,lonlim)
reads
the data for the part of the world within the latitude and longitude limits. The limits must be
two-element vectors in units of degrees.
Background
TerrainBase is a global model of terrain and bathymetry on a regular 5-minute grid (approximately 10 km resolution). It is a compilation of the public domain data from almost 20 different sources, including the DCW-DEM and ETOPO5. The data set was created by the National Geophysical Data Center and World Data Center-A for Solid Earth Geophysics in Boulder, Colorado.
