ConclusionsConclusions
Extensive Geographic Information projects needs multi-year planning
Source-data is not interoperable Data maintenance is critical Data sources and quality are generally
difficult to assess

Suggested action planSuggested action plan 1. Reference data1. Reference data
– centrally stored, used by all
2. Cataloguing2. Cataloguing– UN system data and GIS related projects– links to other metadata resources
3. Co-ordination and agreements3. Co-ordination and agreements– internal to UN system– with NMAs, other (official) data owners– distributed databases

fundamental data is NOT all the data needed ... but the common data needed by most
(UN) users should be (relatively) scale-freeshould be (relatively) scale-free
– today’s technology allowing on-the-fly feature selection/generalisation

Ref.data : suggested stepsRef.data : suggested steps
1. Assess UN various internal needs
2. Define a common “reference data”
- in co-ordination with other initiatives
3. Use current global/regional initiatives
4. Support filling out gaps
- emerging regional initiatives
- harmonisation initiatives
- data developments
