Famine
► Data Management
► Datasets of Interest
► Data Selection

 Geogratis.ca  NTDB topo data and raster imagery now free!
►
Provincial Governments
 Ontario  OGDE via libraries or vendors
 Manitoba  free from download
 BC and Alberta  pay for some free download for others

Future Historical GIS
1860’s Map of Toronto with roads overlayed. Note the Lakeshore highway’s
location.
Open Street Map
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
Future  GPS / GIS Convergence

Communication & Teaching
 GEODATA-l
Listserv
New Datasets
Software upgrades
 Workshops
 One
on one teaching
 One GGR grad course
 ESRI Virtual Campus
