The Evolution of Land Surveying Technology in Alberta

These articles trace land survey measurement technology from the time of early mapping and surveying in Western Canada to the relatively recent application of GPS technology. They depict the greatest evolution in land surveying technology in history – the period from about 1960 to the early 2000s. This period witnessed the transformation in measurement technology from transit and chain to GPS, and in survey computation from logarithms to the sophisticated programs and computers of the early 21^st Century.  They were originally published from 2021 to 2023 in ALS News a quarterly publication of the Alberta Land Surveyors Association.
