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

Map Types Volume Data

• Isopleth, Stepped Surface, Hypsometric
• Gridded fishnet
• Realistic perspective
• Hill-shaded
• Image map

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
