Remote sensing includes imagery and other data collected from satellites, balloons, and drones.įinally, GIS can also include data in table or spreadsheet form, such as population demographics. Remote sensing provides another tool that can be integrated into a GIS. An example of this kind of information is computer data collected by satellites that show land use-the location of farms, towns, and forests. Photo interpretation involves analyzing aerial photographs and assessing the features that appear.ĭigital data can also be entered into GIS. Photographic interpretation is a major part of GIS. Cartographic data may also include survey data and mapping information that can be directly entered into a GIS. These applications may include cartographic data, photographic data, digital data, or data in spreadsheets.Ĭartographic data are already in map form, and may include such information as the location of rivers, roads, hills, and valleys.

GIS applications include both hardware and software systems. Such a map would help people determine where water supplies are most at risk. For example, using GIS, a single map could include sites that produce pollution, such as factories, and sites that are sensitive to pollution, such as wetlands and rivers. With GIS technology, people can compare the locations of different things in order to discover how they relate to each other. It can include information about the sites of factories, farms, and schools, or storm drains, roads, and electric power lines. It can include information about the landscape, such as the location of streams, different kinds of vegetation, and different kinds of soil. The system can include data about people, such as population, income, or education level. Many different types of information can be compared and contrasted using GIS.

The location can be expressed in many different ways, such as latitude and longitude, address, or ZIP code. GIS can use any information that includes location. GIS technology is a crucial part of spatial data infrastructure, which the White House defines as “the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data.”

By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships. A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface.
