1. Purpose of the Global Map project
The concept of Global Mapping, and
the establishment of an international body for Global Mapping, was first
proposed by the Ministry of Construction of Japan (MOC) in 1992; and in 1994
the Geographical Survey Institute of Japan (GSI) proposed the first draft Map
Specifications. The project currently involves the participation of many
interested nations. The main objective of this global project is to bring all
nations and concerned organizations together to develop and provide easy and
open access to global digital geographic information at a scale of 1:1 million.
This would be used to facilitate the implementation of global agreements and
conventions for environmental protection, for monitoring of major environmental
phenomena and to encourage economic growth within the context of sustainable development.
As part of this objective, a Global Map product will be developed to this
specification.
The Global Map will also contribute
to the development of a Global Spatial Data Infrastructure.
2. Brief Specification of Global Map data
1) Spatial resolution: ca. 1km
(equivalent to 1:1,000,000 scale)
2) 8 layers
a. Vector data (point, line, area)
Boundaries (Administrative/Coast),
Drainage (Rivers/Lakes),
Transportation (
b. Raster data (grid)
Elevation, Land Cover, Land Use,
Vegetation
3. Liaison description
WGISS will interact with the Global
Map project to exchange the information and to seek the area for give and take
collaboration.
