12. Data Structure Internet GIS of Antarctica Meta data Home data Attribute data Vector data Image data Scientific research Groundwork surveying and mapping Hydrographic data Elevation data

13. Home Page Themes Scientific research Groundwork surveying and mapping Stations information Online help

14. Data Processing Conversion to a standard geographic coordinate system possible and may be required Standard elements of spatial data accuracy are being considered i.e. positional, logical consistency etc. Data revision strategy being developed

15. Methods of Data Representation Imagery Dynamic maps – time series analysis i.e snowline variation over time 3D map browsing – zooming, panning, rotating. 3D terrain fly through/animation

16. Different Rendering Styles for Same Space

17. Sample of On-Line Representation of Antarctic Data

18. Multimedia Content Text Pictures Video Audio

19. Suggested Data Layers Water system: Coastlines, lakes, rivers, unmelted ice areas, ice shelf data Island maps: Boundaries, buildings Water sytems + Islands = base framework Elevation data Geodetic control stations Placenames

20. Suggested Subject Areas for Investigation Seabirds Vegetation such as Lichen or Moss The Impact of Human Activity in the Antarctic Ecosystem

21. Technical Approach

22. Software GEOSTAR GIS Extensive functionality Based on an approach that uses the latest object-oriented methods

23. GeoStar GIS Software developed by Wuhan University On-line functions include: Vivid virtual 3D relief flying Making Color relief map Data representation using various media Display and cruise based on vector and raster map, Defining communication net and the best path query Attribute query Display, cruise and zoom of alterable scale vector and raster maps Linkages of hot words, multimedia information and map Navigation function by connecting with GPS.
