The central function of a geographic information system is to provide a visual representation of data. It is estimated that 80% of the data we consider has a geospatial element of some form. GIS provides a means for that data to be stored in a database and then represented visually in a mapped format.
There are numerous ways in which GIS technology can be used. The most common ones are:
- Management of resources
- Investigations of the earth’s surface that is scientific in nature
- Archeological uses
- Planning of locations and management of assets
- Urban & regional planning
- Criminology matters
- An Impact assessment of the environment
- The assessment and eventual development of infrastructure
- Studies of the demographics of an area plus its population
- Analysis with regards to engineering
Some of the common instances where you will find the GIS in use include:
- Emergency response teams normally use GIS when they want to collect logistics with regards to how they will move in times of natural disasters.
- The system also comes in handy when authorities want to discover any potential wetlands that need to be protected from the harmful effects brought about by pollution.
