- geospatial framework data of the Earth’s land areas.
- in which to place environmental, economic and social information in its
geographic context.
- a way for individual countries to choose how they will be represented in
a global data base.

- Early attempt in early 1900’s failed.
- promoted by Japan in early 1990’s.
- first meeting in 1996.

- administrative boundaries.
- drainage.
- transportation.
- population centres.
- elevation.
- land cover.
- land use.
- vegetation cover.

- correct errors in data sets:
- validate land cover data sets.
- fit raster data and vector data sets together.
- submit to ICGM Secretariat for quality assurance and publication on web:
- licence for commercial applications.

- “capacity” within National Mapping Agencies:
- countries (Japan, Columbia) are willing to assist other countries in
preparing Global Map contribution.
- ESRI grant of software and training to prepare national map and put it
into the Global Spatial Data Infrastructure.
- similar program by Intergraph to provide software and training to
exploit Open GIS Consortium protocols.
- 1:1M scale is too small for many island nations.
- permit increased/variable data density (~ larger scale) within Global
Map.

- VMap level 0 deemed not robust enough for regional/local applications:
- derive from new, developing national base (USA – National Map).
- major correction effort, replace with new data (Canada).
- consistent representation for Europe (EuroGeographics).
- Data distribution policy:
- free, unrestricted for non-commercial use.
- licence (nominal fee) by data provider for commercial use.
- national boundaries remain sensitive particularly in developing
countries.

- to enable greater participation and hasten completion while making it
easier to assemble and use for global, regional, national and local
applications.
- considerations:
- permit variable data density (scale).
- permit native data structures and formats used in common commercial
GIS.
- distributed (rather than centralized) access.
- additional thematic layers.
- include ocean bathymetry and thematic information.
