Geographic Information System (GIS) Modeling

The term modeling is used in many ways and has many different meanings. Representing a part of the real world can be a modeling process; This is because the resulting model will have characteristics in common with the real world, allowing us to conduct studies and work on the model rather than the real world in order to test what would happen if conditions changed and the possibilities were varied (1).

In GIS environment, a map is a miniature representation of a part of the real world, and is the most common model. Databases are an important class of models. As the stored data represent some real-world phenomena, they are also models. A database can store a large amount of data, and provides the ability to perform many operations on the stored data, while digital forms also have tremendous advantages over paper forms, and are more flexible and easy to modify, and allow the completion of computer simulations (1).

The best example to explain modeling is maps.

Maps are complex tools that contain a lot of information, and some of that information appears clearly in the symbols that explain the map, usually a lot of information provided by maps is cleverly hidden between their lines, symbols and colors.

To create a geographic information system that includes complex and useful information in the…
