Seeing Data with GIS: From Paper Maps to Immersive Visualizations Matt Gregory Forest Ecosystems and Society GIS Day 2008
Who am I? GIS Analyst Programmer Total map geek
In the old days … (before 1996) Paper maps were the best way to ‘see’ data Paper maps continue to be important as one way to display and archive information BUT, with the web comes new possibilities …
Google Maps launched (web based mapping that can be used on your own website) Google Earth launched Microsoft Virtual Earth launched OpenStreetMap (users around the world create roads with handheld GPSs) Your lifespan in GIS web mapping MapQuest launched for driving directions 1998 First online GIS web mapping and analysis programs Terraserver (images and topo maps) 1999 National Atlas of Canada available online 2002 NASA Worldwind launched (first 3D world viewer) Many users customize these programs as ‘mash-ups'
Web mapping: pros and cons Deliver up-to- date data User can often ‘personalize’ map Can be less expensive than paper maps for users ProsCons Need the internet Limited screen space Can be expensive to produce and maintain for developers
Examples City of Corvallis web mapping Mashup example: Geocaching.com OpenStreetMap Google Earth GNNViz
On to some examples!
Future of GeoData Visualization? Some guesses … 3-D visualizations will get faster and imagery will get more detailed Handheld devices and phones will not only be able to display but also collect data Communication in web mapping sites (chat, avatars) not far off
