Definition of Global Map
(by ISCGM)

Global Map is a group of global
geographic data sets of known and
verified quality, with consistent
specifications which will be open to
the public, considered a common
asset of mankind and distributed
worldwide at marginal cost.
Current Global Data Sets for
Global Environment
DEM: GTOPO30 (Global 30 arc second elevation data
set)
(EROS Data Center/USGS)
Cartography : DCW (Digital Chart of the World)
> VMAP(Vector Map) Level 0
(US National Imagery and Mapping Agency)
Land use/cover : GLCC (Global Land Cover
Characterization) (EROS Data Center/USGS and IGBP
DIS Land Cover WG)
Issues of Existing Global
Data Sets
Uncertain quality
Some data sets do not have clear quality information.
Global inhomogeneity
Data quality is not globally homogenous.
Uncertain schedule for data revision
No plan of updating data.
Global Mapping Initiative
through cooperation between
national, regional and international organizations
Why do existing global data sets need to be improved?
Shaded Relief Map of Nepal (source GTOPO30)
Why do existing global data sets need to be improved?
River and Road Network in VMAP Level 0
Principles of the Global Map
Covers
the whole land area.
Spatial resolution: 1 km,
nearly equivalent to map at the scale of
1:1,000,000
Open and worldwide distribution at
marginal cost.
Revised every five years.

Programme for the further
implementation of AGENDA21
“A supportive environment needs to be
established ... to facilitate public access
to information on global environmental
issues ... using ... such tools as
geographic information systems and
video transmission technology, including
global mapping. ...” (Paragraph 112 :
Adopted document of the UN General
Assembly, June 1997)

drainage system (rivers and lakes),
transportation (roads, railways, airport etc.),
administrative boundaries,
population centers
Raster Layers
 elevation, vegetation, land cover, land use
Existing Datasets to be Used

Global 30 Arc Second Elevation Data Set
 Elevation (DEM)

Global Land Cover Characteristics Database
 Land Cover
 Land Use
 Vegetation

VMAP Level 0
 Drainage System (rivers, streams, lakes)
 Transportation (roads, railways, airports)
 Political Boundaries (including coastlines)
 Populated Places
Recommendation Letter of
Global Mapping by UN
 UN
sent the letter of ISCGM inviting
Global Mapping Project and the letter
of UN recommending the project to
the head of National Mapping
Organizations in November 1998.
SCAR/WG-GGI participates
in Global Mapping Project
SCAR WG-GGI participated in the
Global Mapping Project on March 9,
1999.
 Mr. Drew Clarke, Chairman of SCAR
WG-GGI has been invited as one of
ISCGM members since 5th Meeting in
1998.

Global Map Data for Antarctic
British Antarctic Survey (BAS) is
simplifying the revised Antarctic Digital
Database (ADD) to a 1:1,000,000 scale
version.
 The data are under being checked by
ISCGM Secretariat.
 It will be returned to BAS, and revised
until 2001.

Timetable of
Global Mapping

First phase - 2000
 Release Global Map ver. 1.0
prepared from existing global scale
geographic data

Second phase
 Regular
2001 -
update (every five years) and
Promotion of data use
Global Mapping Forum 2000
Hiroshima
 Global Mapping Forum 2000 will be held in Hiroshima
from 28 to 30 Nov. 2000
 Aims :
Commemorate completion of Global Map Version 1.0
Declare start of distribution of Global Mapping Data
Urge usage by introducing examples of application
Discuss plan for promotion of Phase 2 of the Project
 Distributing GM sample data to Researchers
Future Cooperation
ISCGM / SCAR WG-GGI
Need to revise and update the data
periodically.
 Secretariat of ISCGM and SCAR WGGGI will continue to communicate.
 If necessary, GSI will make effort to
contribute such activities as a member
of WG-GGI.
