What is GIS?

The Courier asked ChatGPT to explain GIS, then fact-checked the AI tool’s explanation against other sources.

This is what the AI provided:

“GIS, which stands for Geographic Information Systems, is a type of digital tool that helps users visualize, analyze, and understand patterns and relationships in spatial data. It’s like a high-tech version of a map.

“At its core, GIS is a software platform that combines spatial data (information about the physical location of things on the earth’s surface) with attribute data (information about those things). For example, a GIS might layer a map of a city (the spatial data) with information about population density, street names, and land use (the attribute data).

“GIS is used by a wide range of industries for a variety of purposes, such as tracking disease outbreaks by the health sector, land use planning by urban planners, and assessing the environmental impact of construction projects by environmental scientists.”
