Since the creation of the first Geographic Information System (GIS) in the 1960s, technology has advanced significantly. But have you ever pondered about the origins and early history of GIS?
Roger Tomlinson, a Canadian urban planner, invented GIS technology in the late 1960s. He was engaged on a project for the Canadian government at the time to produce a thorough map of land usage across the entire nation. Tomlinson realised he required a mechanism to effectively store and examine a lot of geographically related data in order to complete this assignment. He therefore had the thought to develop a system that could do just that utilising a computer.
The first GIS was called the Canada Geographic Information System (CGIS) and was used to map land use and resources across Canada. The CGIS was groundbreaking because it was the first system that allowed users to store, manipulate, and analyze geographically-referenced data all in one place. This made it much easier to understand relationships between different pieces of information, such as how a particular land use might affect the environment or how the distribution of resources might impact a community.
In the years that followed, GIS technology continued to evolve and improve. In the 1970s, the US military began using GIS to plan and execute operations, and by the 1980s, GIS technology had become widely adopted in the private sector for everything from real estate to retail.
Today, GIS is an essential tool for a wide range of industries, from urban planning and transportation to natural resource management and emergency response. And with the advancement of technology like satellite imagery and GPS, the possibilities for GIS are endless.
So, there you have it, a brief history of GIS and how it all began. It’s a fascinating field with an interesting past, and one that continues to play a crucial role in shaping our world today.
