Learn more about GIS
Geographic Information Systems are tools used to analyze and present geographic and spatial data in the form of maps and layered visualizations. You can use GIS for monitoring agriculture, surveying, geology, and city planning.
Frequently asked questions
A geographic information system (GIS) is a system designed to collect, store, analyze, and process data connected to positions on the Earth’s surface. Spatial data can include natural features such as elevation and river flow, or it can include the built environment such as buildings and traffic networks. A GIS can be used to visualize spatial data in the form of customized maps that present datasets gathered from many sources. But the true power of a GIS is that it can process and analyze spatial datasets to answer questions and solve problems relating to the natural or built environment. GIS analysis can include distance measurements, statistical methods, and prediction and forecasting. While a GIS is used primarily to analyze and visualize spatial data, it can also process temporal datasets that contain information about data that changes over time within a certain area — for example, sun exposure throughout the year or traffic levels over a week.
