A geographic information system, more commonly known simply as GIS, is a powerful system that allows us to visualize, analyze and interpret data. This allows us to better understand trends, patterns and relationships between pieces of data. With GIS, it is possible to perform a number of tasks, from creating maps to visualizing various scenarios. As a result, it is a very powerful tool.

What Exactly is GIS?

Mapping With GISGIS is a computer system that can be used by businesses, organizations, schools, individuals and government entities. Those who use GIS are looking for unique and innovative ways to solve a number of problems. Through the use of GIS, information about the world is stored as a collection of layers that are linked together by a common locational component, such as zip code, longitude and latitude, road name or census tract name.

Using this information, it is possible to analyze patterns and trends, GIS is the go-to technology when it comes to making better decisions about a location. For example, GIS is extremely useful in things like route selection, snow event analysis, natural resource extraction, fleet activity, personnel safety, accountability and efficiency and evacuation planning.

How is GIS Used?

GIS has a number of applications. It can be used to:

  • Create Maps
  • Present Ideas
  • Visualize Solutions
  • Integrate Information
  • Develop Effective Solutions

GIS Components

GIS technology consists of a number of components that work together to form the entire solution. An effective geographical information system consists of hardware, software, data and people.

Hardware

The hardware utilized in GIS includes all of the equipment that is needed for data collection, data analysis and all of the numerous activities that are associated with geospatial analysis. The workstation is the central hardware component that runs the GIS software and serves as the attachment point for additional equipment.

Data collection requires additional equipment, such as a digitizer and GPS data logger. Handheld field technology is extremely important for data collection in the GIS industry, and web servers have also become important with the advent of web mapping.

Software

The most crucial piece of software is the GIS application. It is necessary for creating, analyzing and editing spatial and attribute data, so GIS software has a number of geospatial capabilities. There are also extensions and add-ons that extend the capabilities of GIS software, making it even more powerful than before.

Data

For any GIS, data is the core component. There are two different types of data that are commonly used in GIS: raster data and vector data. Raster data is cell-based information, including digital elevation models and aerial or satellite imagery. Vector data refers to spatial data that is represented as lines, points and polygons.

In addition to raster and vector data, there is also usually attribute data. Attribute data is generally defined as extra information about each of the spatial features presented in a tabular formation. The documentation of GIS data sets is known as metadata, which contains information like when the data was created, the coordinate system, when the data was most recently updated, who created the data and that person’s contact information.
