Update an area covering over 30.000 sqkm, 4 spatial
data themes and 16 layers
MAIN GOALS
Fallow update rules described in more than 1000
pages of technical documentation
Correction for small and time consuming errors resulted from
the update process
QC of the geometry against over 150 topologic rules
with 0.1% tolerance
Keep an accurate record of all the changes
Maintain the planned schedular for the delivery of the
data

Keep a record of all the actions and
progress Have a tracking of all the modification done on data
Ensure all steps of the data processing are made
In order to:
Have a status in real time of the current state and take
appropriate decisions
Have a general overview of the effort involved at
present and better adjust resources for the next cycle.
