What is GIS?

Geographic information system, or GIS, is a way of collecting, storage and displaying data rooted in geographical space and time. The way people interact with this system are usually the addition of gathered data to the system, or by means of a system to draw conclusions about the real world. Many different professions interact with GIS different ways to achieve different goals, but this type of system is particularly useful in professions that require detailed geographically oriented data such as geology. The quality of the system is almost entirely dependent on the quality of data, which in turn depends on the skills of people who collect data. While hardware and software connected to the system are also very important, real data is the heart of GIS. GIS is in its most basic mapping system that can be used for cartographic purposes. In generally, however, people using this type of system have additional data used. This data is tied to the space and date of recording and can be used in all types of applications in dependentOutness on the subject.

At least this type of system requires an arranged way of determining where things are. For each relevant geographical point that exists, there must be a point in the mapping system. Because there may be something else at any moment, it is important that this type of system is often updated.

This concept of binding information to the place may be difficult to understand abstract, but in fact it is very clear. For example, if the police were studying a crime formula in a particular city, they could use a map of police incidents to visualize, where there is usually a crime and place officers accordingly. If the data used in this application should include crimes, the age of the perpetrator and the time, the person who was interested in the relationship between school clocks and youth involvement in drug crimes could be able to make a convincing argument that children should bekept longer if the data support this claim. The point is that GIS is only useful for information about geographical functions. Everything in the human world occurs both in place and time, and therefore GIS can be used as a valuable tool to understand most of everything in the human world.
