  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

  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
