Introduction Geographic information systems are computerized systems for collecting, storing, processing, and outputting spatial reference information (Obermeyer and Pinto, 1994). Data collection is the process of entering information into the system (Eisntein, 2001). The data used in GIS is obtained from various sources of various kinds and stored in various ways (Eistein, 2001). Mutluoglu and Ceylan (2009) noted that the main components of GIS are database formation. Over 70% of time and cost are spent developing this database.
The Geographic Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage, and display all kinds of geographic data. The keyword of this technology is geography. In other words, some of the data is spatial. In other words, the data references the location on the earth in some way. Combined with this data is usually tabular data called attribute data. Attribute data can generally be defined as additional information about each spatial feature. One example is school. The actual location of the school is spatial data. Other data such as school name, education level, student's abilities are attribute data.
The Geographic Information System (GIS) is a "computer system for capturing, managing, integrating, manipulating, analyzing and displaying data from the spatial reference Earth" (McDonnell and Kemp, 1995, 42 page). Another person, Clarke, defines GIS as "an automatic system for capturing, storing, searching, analyzing, and displaying spatial data." (2) The third definition of Huxhold and Levinsohn states that GIS is "a collection of information technologies that collect, save, manipulate, analyze, render maps, a collection of data and programs, descriptive Information ". (3) Therefore, in order to support the decision-making process, it can be concluded that GI is a computer system that collects data, processes them, and outputs them in several formats such as maps and statistical tables I can do it.
