A Geographic Information System (GIS) uses digital hardware and software to collect, manage, analyze, and display information about specific locations. GIS is a way for us to understand our world in a visual geospatial format. It can be used to analyze social data such as crime patterns and population demographics. GIS can be helpful in analyzing physical features such as watershed and soil characteristics for biological studies, agricultural interests, and environmental issues. It can also be used for city and regional planning and for emergency response development.
