Presentation Transcript

  1. Cartography, Map Production and GeoVisualization Geog 176B Lecture 10: Longley Chapters 12,13

  2. Visual Variables: Bertin Quantitative Qualitative

  3. Map Types: Point Data • Reference • Topographic • Dot • Picture Symbol • Graduated Symbol • Multivariate symbol

  4. Reference & Topo Map

  5. Simple Dot Maphttp://www.cybergeography.org/atlas/

  6. Picture Symbols/Icon Maphttp://tabi.joy.ne.jp/h-tokachigawa/icon/map.gif

  7. Graduated Symbol Source: Dent

  8. Multivariate Symbol: Chernoff FacesSource: Eugene Turner, Dan Dorling

  9. Map Types: Line Data • Network • Flow • Isopleth • Reference

  10. Network Mapshttp://www.360.net http://www.luxembourg.co.uk/pics/railnetw.jpg

  11. Flow Map: Europe Internet Trafficwww.cybergeography.org/atlas/census.html

  12. Isoline (isobar)

  13. Map Types: Area Data • Choropleth • Dasymetric • Area qualitative • Stepped surface • Hypsometric • Reference

  14. Area Qualitative Maphttp://www.townofbrighton.org/

  15. Stepped Surface

  16. Hypsometric

  17. Choropleth Mapping

  18. Fields and Regions

  19. 2D Web Cartography • HTML embeds PNG, JPEG and GIF • Animation possible with GIF • Drawing extensions with SVG (XML) • Otherwise, need JAVA or FLASH • GIS data can be web enabled with on-line products such as Arc/IMS and GeoMedia Web Map, MapInfo Envinsa • Map open source tools

  20. Map Types: Volume Data • [Isopleth, Stepped Surface, Hypsometric] • Gridded fishnet • Realistic perspective • Hill-shaded • Image map

  21. 2.5D Methods

  22. Hill shading

  23. DOQ/Vector integration

  24. Oakland: Integration of Hi-Res Imagery

  25. 2.75D Anaglyphic stereo

  26. Map Types: Time • Multiple views • Animation • Moving map • Fly thru • Fly by

  27. Animations

  28. 3D Web Cartography • Unload interaction functions to web client • Build and make visible 3D models • VRML established as 3D web equivalent of HTML • GeoVRML is geographically enabled VRML • GML, X3D now available

  29. (Geo)VRML • Public domain Web tools (CosmoCreate and Player) • Works for both immersive and passive displays • Symbolization at feature level, any dimension object • Integrated environment to develop, test and distribute cartographic methods • Combine traditional cartographic portrayal techniques, animation, and 3-dimensional display • Importance of nodes and georeferencing Worlds (GeoVRML 1.0) • Incorporates visual field depth via proximity sensor and zoom

  30. CosmoWorlds VRML Authoring Package

  31. VRML Object modeling

  32. VRML: Worlds

  33. World plus texture

  34. Dibiase: Public/Private

  35. EDA/Scientific Visualizationwww.ais.fraunhofer.de/NWEnglandAnalysis.gif

  36. Professional map publishing

  37. Avenza, ArcPress etc.
