Most GIS professionals will recognize Roger Tomlinson as the 'Father of GIS." But how did he come to be known as that? A serendipitous meeting on a Spartan Air Services flight would pave the way for what would become the Canadian Geographic Information System, launched in the early 1960s. The system was born out of pure necessity, as manual methods to do the work were much too costly. The first sentence of the Abstract from his 1974 thesis (attached), which was surprisingly for a doctorate in Philosophy, sums up the objective nicely:
Manual and computer-aided techniques for handling location-specific data are viewed, not in terms of their ability to produce maps, but in the broader role of storing, manipulating, and displaying such data.
Today's GIS fits this description perfectly, as location data is interwoven with other data sources to derive insights that are not obvious without a spatial component. Location Intelligence as it has been termed is now part of analytics across enterprises and the public sector.
Tomlinson went on to serve in many important capacities related to the science of GIS. He was Chairman of the International Geographical Union GIS Commission for 12 years. He pioneered the concepts of worldwide geographical data availability as Chairman of the IGU Global Database Planning Project in 1988. He was also a president of the Canadian Association of Geographers.
His 2003 book, Thinking About GIS: Geographic Information System Planning for Managers, is essential for anyone leading a GIS function.
Tomlinson died in 2014. Here are several links if you want to explore his impact further:
