Conclusions

• Without information people are living in
  blindness
• Any geo-science needs geo-data and
  geo-information to achieve its goals and to
  tackle todays complexity of earth-related
  problems, increasing geo-information is required
• Geomatics is the science concerned with the
  developing of technologies and methodologies for
  collecting, storing, processing and dissemination
  of geo-data and geo-information
• The processing of the mass of geo-data emerging
  from new sensor technologies requires automation
