A geographic information system (GIS) allows you to study and explore everything about a place. With a GIS, you can identify and analyze the land features, climate, boundaries, population, resources, and many other things about places that interest you. In the past, you needed to use paper maps, globes, and a variety of hard-copy data sources to perform these analyses. Now, a GIS makes the maps, globes, data, and analysis tools available on your computer, allowing you to perform sophisticated analysis, map your results, and store and share your information digitally.
An example of the type of map you could study or create in a GIS is a population density map, which shows the distribution of population in relation to specific areas (e.g., cities, census tracts, counties, states, countries). Population density information is important to consider when you are mapping areas that vary greatly in size; for example, 200,000 people living in an 8-square-mile county and 200,000 people living in an 80-square-mile county are very different conditions. Population density, in turn, provides context for other maps in your study, which may show demographics, economic statistics, or housing prices.
