What is a major benefit of GPS and GIS technologies in Canadian geography?

• A. They enable precise mapping, spatial analysis, cartography, remote sensing, land-use planning, and disaster response.
• B. They reduce the need for field surveys and ground truthing.
• C. They provide entertainment mapping apps for tourism.
• D. They predict weather patterns.

Answer: (A)

GPS and GIS give geographers the ability to map places with precise coordinates and understand how things relate across space. This combination lets us create accurate maps, perform spatial analysis, and bring together data from cartography, remote sensing, and various layers of information. In Canada’s vast and varied landscape, that means we can map remote northern regions, plan transportation and resource developments across huge distances, manage land use and natural resources, and coordinate timely disaster responses for events like wildfires or floods. The strength lies in turning exact location data into usable maps and models that guide decisions about where and how to act.

While GIS and GPS can reduce some field work by providing remotely gathered data, ground truthing and verification remain important for accuracy. Weather prediction, on the other hand, isn’t a primary function of GPS and GIS, and entertainment-focused mapping apps aren’t what these technologies are meant to optimize in geography.
