July 1999
Where are we from...


3M inhabitants
187.000 Km2
Why to worry about this in Uruguay?

National Spatial Data Infrastructure
under (fast) construction including:
• Full National Coverage, Digital
Cartography 1:50.000 by November 1999
• Also DEM for the same coverage
• Rural Cadastral already digital
• Urban Cadastral ongoing (>80% ready)
• A FGDC-compatible Clearinghouse node
available on Internet since april’99
Overall Status at the national level
 Clearinghouse
up and running
 Few datasets available online
 Major data providers expected to be
associated prior July 2000
 Quality? Lineage?? ...
 De Facto Technology transfer from the
University
Research at University (1)
Main interest is in improving accuracy of
available datasets
 Concentrated in meteorological data(U),
DEM(U), census(P) and now
cartography(P)
 Research mostly motivated by
engineering applications / demands
 Few (if any!) basic research in this topic

Research at University (2)
 Statisticians
& geographers hardly
interested.
 Surveyors more involved
 Applied computer science application,
closely related with Data Mining
 High variety of tools available and in use,
including Neural Networks, HPC, etc.
Next steps at the national level
Expected growing demands coming
from government and large publicly
owned companies for the next 5 years
 New Clearinghouse nodes under
development
 Projects on DEM(U), oceanographic
data(U), fraud detection for utility
companies(U)

Next Steps at the University level
Research focused on some specific
applications, like DEM and time-varying
datasets
 Reinforce connections with government
and industry
 Strengthen connections with other
research groups abroad (this meeting!)

