Whether you are aware of it or not, GIS plays a significant role in your everyday life—from the navigation apps on your phone to the delivery services that bring packages to your door on time.
GIS stands for Geographic Information Systems, a technology used to store, analyze, and visualize spatial data. In its simplest form, GIS allows us to take information from maps and other data sources and make it more accessible and useful through visual representation and analysis.
At its core, GIS consists of several key components:
- Hardware – Computers and servers that store, manage, and process spatial data.
- Software – Programs such as ArcGIS, QGIS, and Google Earth Engine that allow users to visualize and analyze spatial data.
- Data – The geographic data itself, which can include information on locations, shapes, attributes, and relationships.
- People – The professionals, analysts, and researchers who collect, manage, and interpret the data.
- Methods – The procedures and techniques used for data collection, analysis, and presentation.
How does GIS work? GIS integrates layers of data into maps. Each layer represents a different type of information (e.g., streets, land use, population density), and users can manipulate these layers to see how different variables relate to each other spatially. For example, urban planners might overlay a map of population growth with one showing existing infrastructure to make decisions about where new roads should be built.
