A Temporal Quiz
Im the beginning of the end. You see me twice
in a week, but not in a day. Once in a year, but
twice in a decade. What am I ?

ISO/TC 211
International Organization for Standardization Tec
hnical Committee 211
  • Geographic information/Geomatics

Steinar Høseggen, October 2001

Some objectives ...
  • increase the understanding and usage of
    geographic information
  • increase the availability, access, integration,
    and sharing of geographic information
  • promote the efficient, effective, and economic
    use of digital geographic information and
    associated hardware and software systems
  • contribute to a unified approach to addressing
    global ecological and humanitarian problems
