Resumen

The objective of this article is to describe the recently created international
program TREx (TanDEM-X High Resolution Elevation Data
Exchange Program) whose purpose is to obtain a digital surface model
with global coverage (GDEM) of high resolution and quality. The role
of Spain in the TREx program is also discussed.
The digital models of surface have multiple applications in the civil
field and in the military field: geological or hydrological studies, analysis
of mobility, deployment of units, etc. The GDEMs try to represent
the elevations of the entire globe while maintaining a level of quality
in the spatial resolution and in the absolute and relative precisions of
their coordinates.
The TREx program, due to its global coverage, needs a great international
cooperation. Currently, 32 nations participate, including Spain.
