  2. Presentation Overview • Proposed Elements of the Atlas • Technical Approach

  3. Proposed Elements of the Atlas

  4. Primary Elements • Functionality • Content

  5. Functionality • 4 Key Functional Modules • Atlas Browsing • Display and Simulation • Query • Analysis

  6. Atlas Browsing • Catalogue • Sheet map browser • Switching between different maps

  7. Display and Simulation • Manipulation of display parameters • Interactive legends • Animation • 3D Display

  8. Query • Bi-directional query • Keyword and Expression Query • Fuzzy query

  9. Analysis • Perimeter and Area Calculation • Volumetric Calculation • Thematic Analysis

  10. Content • Geo-spatial Data • Multi-media material • Subject areas

  11. Geo-spatial Data • Vector maps • Raster data including satellite imagery • Attribute data • Large database • 90 GB – Physical, geological, meteorological • 40 GB - Geodetic Control, GPS, Metadata

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

  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.

  24. Technical Architecture Client/Server based on Intranet Spatial data management engine and interface (API) Map scanning vectorizing Browser/Server based on Internet Intranet &Intranet GIS Application Server: Register Service Catalog Service Projection Service Map Service Feature Service Analysis Service Image Service DEM Service 3D Service Client side: Html viewer Applet Viewer Data Side File RDBMS ORDBMS ODBMS Digital pho-togram Image processing DEM and application Mapping Spatial query Spatial analysis

  25. Programming Approach • Server side applications programmed using JAVA 2 • Multi-platform (Microsoft, UNIX)
