ROGER TOMLINSON was a freshly minted geographer in his twenties
when he came up with a concept that would revolutionize his field.
It was the early 1960s, and he was working at an aerial surveying
and mapping company in Ottawa, involved in a project to find a site
for a pulp and paper mill in Kenya. The job required manual analysis
of reams of maps at different scales, a time-consuming and expensive
endeavour. After he was told twice to sharpen his pencil on cost
estimates for the project, Tomlinson thought that if there were a
way of entering maps into a computer, it might crunch the information
more effectively and cheaply. Soon after, he began developing the
world's first geographic information system (GIS).
GIS is a computer system for integrating, analyzing and displaying
data about Earth from maps, charts or related statistics. The technology
is used all over the world for national defence, pollution monitoring,
policing, school-bus routing and forestry management, among countless
other applications. For his singular
vision and achievement in the field of geography, Tomlinson has
been awarded the RCGS Gold Medal.
The widespread use of GIS shows that "geography is becoming
a vital component of just about every job you can think of," says
Tomlinson, who likens the impact of GIS on geography to that of the
microscope on biology. "We've got a tool that allows
us to describe the world with much greater facility than we ever
have before. And, by definition, that's going to change what
we understand about it."
