A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships.
A geographic information system (GIS) is a framework for gathering, managing, and analyzing data. Rooted in the science of geography, GIS integrates many types of data. It analyzes spatial location and organizes layers of information into visualizations using maps and 3D scenes. With this unique capability, GIS reveals deeper insights into data, such as patterns, relationships, and situations—helping users make smarter decisions.
Geographic Information Systems (GIS) store, analyze and visualize data for geographic positions on Earth’s surface. GIS is a computer-based tool that examines spatial relationships, patterns and trends. By connecting geography with data, GIS better understands data using a geographic context.
The 4 main ideas of Geographic Information Systems (GIS) are:
- Create geographic data;
- Manage it in a database;
- Analyze and find patterns;
- Visualize it on a map.
...A GIS allows you to visualize your data as a map...What’s more, GIS systems aren’t static. They allow us to ask complex questions—or “queries” as they are called in GIS speak—anytime we like. A GIS system can answer these questions instantly by modifying colors, shapes or highlighting locations on the map...Most people don’t need a GIS, what they really need is the answer to a question. A GIS simply provides us with a more efficient mechanism of obtaining that answer.
A Geographic Information System (GIS) is a computer system that analyzes and displays geographically referenced information. It uses data that is attached to a unique location.
Most of the information we have about our world contains a location reference: Where are USGS streamgages located? Where was a rock sample collected? Exactly where are all of a city's fire hydrants?
