3 1. Outline of Global Map 3

4 Needs for Basic Geographic data The importance of basic geographic data is described in GEOSS 10 Year Implementation plan. GSI contributions to GEO TASK are as follows: TASK-DA-06-05: Guideline for Basic Geographic Data (Final Documents: December 2008) TASK-US-09-03a: Development of Global Map for GEOSS SBAs 4

5 What is Global Map? Digital geographic dataset Covering the whole land area of the earth With consistent specifications Open to the public freely downloadable for non-commercial use 5

6 What is Global Map? Spatial resolution: 1km (1:1,000,000 scale) 8 layers Transportation, Boundaries, Drainage, Population centers, Elevation, Vegetation (Percent Tree Cover), Land Cover, Land Use Update interval: 5 years to be achieved 6

7 Vector layers Boundaries Drainage Coastline, Administrative boundaries Transportation Rivers, Inland water, Dams Population centers Roads, Railways, Airports Location, Name of Cities 7

8 Raster layers Elevation Land cover Information in 1m interval Land use 20 categories Vegetation 9 categories Percent tree cover 8

11 Participation Status Participation of 164 countries and 16 regions (as of ) :97% coverage of the whole land area of the earth Participation Non-participation

12 Global Map - Land Cover Classification: 20 categories (LCCS) Data source : MODIS data 2003 Coordinate system : Longitude/Latitude, Ellipsoid: WGS84 Resolution : 30 arcseconds 12

13 Global Map - Vegetation (Percent Tree Cover) Data value: 0% to 100% (interval: 1%) Data source : MODIS data 2003 Coordinate system : Longitude/Latitude, Ellipsoid: WGS84 Resolution : 30 arcseconds

14 2. Application of Global Map 14

15 Application - Flood Analysis Global Map is used in a flood analysis system IFAS (Integrated Flood Analysis System, developed by Public Works Research Institute). GIS data (Land Information) Global Map (Land Use, Land Cover) Other Data (Soil, Geology) GIS data (DEM) Global Map (Elevation) Parameter Roughness Surface permeability Soil permeability Soil thickness Rock permeability Basin Shape Satellite-based rainfall data Flood Analysis 15

16 Application RGB composite map What is this map? 16

17 Application RGB composite map Gridded Population of the World, Version 3 Center for International Earth Science Information Network (CIESIN) Global Map Percent Tree Cover GSI, Chiba University and Collaborating Organizations Annual Precipitation Meteorological Research Institute, Japan a lot of annual precipitation high population density 17 high Percent Tree Cover 17

18 Application RGB composite map high population density R: Population Density G: Global Map Percent Tree Cover B: Annual Precipitation a lot of annual precipitation high Percent Tree Cover rate 18

19 3. Summary and Conclusion 19

20 Summary and Conclusion Requirement Comparability Usability Reliability Features of Global Map Global Coverage Consistent specifications 5-year update Digital geographic data Open to the public Government authorization Global Map is usable information for sound decision making on GEOSS SBAs. 20
