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

Animations
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

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
