In April of 1976 I moved back to Ottawa to take a job at Carleton University’s Computer Center. This was like a dream to me!
The job was primarily to support academic use of the computer systems and software by students and professors. Each of us had responsibility for certain programs, and since my background was in geography, I ended up supporting certain mapping (SYMAP) and mathematical (MATHLAB) programs.
SYMAP was a very rudimentary (but heavily used) program that could produce maps using the computer printer — made up of typewritten characters overprinted to create densities. Like I said, very rudimentary. Graphic plotters were just emerging, and although the university owned one, there was no decent software for them yet.
Some professors expressed a desire to somehow be able to “overlay” two different maps in order to show various relationships — for example, a map of rock-types and a map of vegetation types, when overlaid, could potentially indicate best places to look for precious minerals… So I took on the challenge and created a SYMAP add-on program which I called SUPERMAP (for its ability to super-impose, not because it was superior!) This became quite popular with some social-economic geographers.
There was already a program called SYMVU that took SYMAP data points and produced a small three-dimensional graphic plot — however it was a cumbersome program and could only output the results to the plotter. Plotted output was very slow and expensive. So I undertook creating a very similar program that would run faster and be able to output the plots on CRT screen monitors. I called it PREVU, and it became quite popular within the Carleton geography and social studies departments.
A geology professor was suitably impressed and asked me to give a special lecture to his class. I accepted and showed how such a system could be used for remote sensing mapping — taking map data from early Earth-mapping satellites and using it to help in mineral exploration. [See also my “side note” at the end of this post for more interesting details]

One year Carleton had a visiting scholar from the university of Edinburgh in Scotland. He had developed one of the World’s first mapping programs that used a graphics plotter, and came to Carleton to continue that development. HIs program, GIMMS, could produce what were at the time high-resolution black and white plots of maps. Because of my background I worked quite closely with the GIMMS project and provided technical support to its users.
In my last year at Carleton, 1975-6, micro computers were just emerging. I saw potential in them, whereas the computer center itself had little interest. But as grad students and professors started inquiring about the potential use of such simple computers, I was given the added responsibility of being their Micro Computer Liaison.


My main project (which took come convincing) was to use a micro computer and a digitizing table to replace the aging and problematic digitizer that the geography department had used for mapping creation. Although the original digitizer was worth close to $100,000, I was successful in creating a functional replacement using a North-Star Micro computer and a new large digitizing tablet — which if I remember correctly cost a total of about $2000.
I have attached a couple of Carleton newsletters which showcase some of the projects I worked on…
Just before I left Carleton to move to Toronto, I participated in a software conversion project. Carleton had decided to move to a Honeywell mainframe after Xerox unexpectedly decided to exit the mainframe business. I converted and certified SYMAP and MATHLAB to run on the Honeywell machine, in cooperation with the companies that produced those software programs.
Side note: the geology professor that I mentioned earlier was named Patrick Arthur Hill. I took a class from him when I was an undergraduate student, and the following year — because I enjoyed his class so much — I actually sat in on his lectures for a class I was not enrolled in. He was an amazing teacher, and I’ve mentioned him to many people as my idea of what a university professor should be. His lectures, although on geology, included all sorts of references to countries around the world, cultures, etc. I remember him even describing how a certain geological formation had affected the music compositions of a particular area!
In any case, when I visited Carleton campus 20 years after I graduated, I tried to look him up. The geology department office told me that he was retired but that he still maintained a box and if I wanted to leave a note I could do so. So I wrote an impromptu note telling him how much I had enjoyed his lectures, reminding him that I had taught a guest lecture for him at one point, and just wishing him well. I was astounded when a few weeks later I got in the mail a handwritten note from him which I present below…

Sadly, I found out that he passed away two years after I left that note… And from his obituary learned a lot more about him that I wish I had known…
