Future Historical GIS
1860’s Map of Toronto with roads overlayed. Note the Lakeshore highway’s
location.

Where do Google
Earth/Maps fit in?
Convergence or Confusion?
Google Earth The Good
It’s
Fun
Geographic Literacy?
Geographic Interest?
Technology Boom
Ease of Use
Collaboration and sharing of hundreds of
digitizing projects
Google Earth The Good
Google Earth The Bad
“Why
do we still fund GIS Projects when
there’s Google Earth”
– Treasury Board Official at Depository Services
Program Function
Google Earth The Ugly
Google Earth GIS Convergence
Can
now convert GIS Layers to KML format
even in ArcGIS http://www.library.utoronto.ca/maplib/map.html
Can
do your own cartography
Can do some analysis
