The Power of Geographical Information Systems Explained
Geographical information systems, also known as GIS, are computer-based tools used for the capture, storage, manipulation, analysis, and presentation of geospatial data. With evolving technology, GIS has become a widely accepted system with a wide range of applications in various fields.
What Makes GIS Stand Out?
The distinguishing features of GIS are its ability to integrate geographical information with non-spatial data and its ability to analyze and visualize the information. This means that GIS can be used to collect, store, and analyze data from diverse sources, including satellite images, aerial photographs, and maps.
Integrating Geographical and Non-Spatial Data
GIS can combine geographical data, such as elevation, weather, or soil type, with non-spatial data, such as demographic and socio-economic data, to build a more comprehensive and holistic view of a particular location. This method can help government entities or business owners to make more informed decisions based on geographic data, such as establishing new stores or planning infrastructure projects.
Analysis and Visualization
GIS can run various analytical tools to extract valuable information from the collected data, such as identifying patterns, trends, and relationships between different variables. GIS analysis can also reveal new insights that may not have been visible through traditional data analysis methods. GIS can also provide intuitive visualizations of data that can be used to explain complex relationships and make informed decisions. For instance, crisis management teams can use GIS data to assess and respond to disasters such as wildfires, earthquakes, and floods.
Examples of GIS Applications
GIS has multiple applications across industries. In health care services, GIS can help identify areas of high disease incidence or lack of health care services. In the insurance industry, GIS can be used to determine the level of risk of natural disasters and accidents. Real estate companies can use GIS to determine the optimal location for new developments based on socio-economic data, land-use patterns, and accessibility.
Key Takeaways on Unlocking the Power of GIS
GIS is a powerful tool that can be used to capture, store, manage, analyze, and visualize geographical data. GIS has the ability to integrate geographical information with non-spatial data, and its analytical tools can provide valuable insights. GIS has various applications across different fields, including crisis management, health care, and real estate. With the continued development of technology, the power of GIS is only set to grow.
