What is GIS?

The GIS conception is mostly associated with the mapping. Actually, the map is only one of the many ways of working with GIS or one of the products of the Geographic Information Systems.

GIS integrates software and hardware with the help of which we can create, store, manage, analyze, visualize and share geographically referenced information. Geographic Information Systems include spatial location of the objects and descriptive information about them. The combining and visualizing of this data helps us to understand the events and the interrelationships between the objects. Which layers with information we will match depends on the problem, which we want to solve with GIS.

Geographic Information Systems can be viewed in three main aspects:

•    Database – Basically, GIS is based on structured database, presenting the behavior and the interrelationships between the objects in the real world.

•    Maps – In GIS, the data can be visualized in the form of maps. The maps describe the location of the objects and the spatial relationships between them. They are a “window to the database”.

•    Models – GIS gives you the ability to model the world around us in a new, modern way. The abilities of GIS for analysis and modeling complex information are extremely valuable in researching the developments of processes and occurrences, analyzing the risks, identify the opportunities and the threats around us.
