Protected areas have preserved their importance from past to present; these must be preserved due to their historical, cultural, economic, social, and natural characteristics. Protected areas in Turkey are managed under the powers and responsibilities of different institutions within the framework of the legislative provisions. It is aimed to develop an object-oriented geographic data model to protect, manage and transfer the Specially Protected Environment Area (SPEA), which is one of the protected area types, to future generations. In line with this purpose, experts related to the study were included in the study to determine the current situation and problem. The study is handled under two elements. First, a semi-structured interview form was made with the expert staff. Expectations, problems, and alternative solutions were tried to be obtained. With this research, an object-oriented SPEA geographic data model was designed as a result of the information obtained from experts and the literature research. In the development of the model, international visionary studies and standards such as LADM, INSPIRE, ISO, and Cadastre 2014 and Beyond were examined. However, the national-scale TNGIS developed in parallel with these studies was discussed, and the model was developed accordingly. UML schemas were used to design the object-oriented model. The use of UML schemes in GIS applications has gained momentum recently. Thus, a geographic data model, including spatial and attribute data, has been designed for SPEA. As a result of the study, it has been determined that protected areas, considered the common property of all humanity, should be protected and transferred to future generations in a good way. Currently, it has been determined that no TNGIS and e-government applications belong to SPEA. It has been determined that this situation may deepen the existing problems in SPEA management. For this reason, object-based geographic data model design has been realized through UML diagrams integrated with TNGIS, and a GIS data model application has been made. The spatial and attribute data of the study area were presented, the topology was established, and the model was implemented. The data were obtained from the study carried out with the General Directorate of Nature Conservation and National Parks, the Ministry of Environment and Urbanization, and experts. Thus, it was possible to make spatial analysis and query. The importance of managing SPEA in a common geographical database throughout the country was emphasized to establish an object-based SPEA management model. In order not to deteriorate the protected areas with structuring under the pressure of the city over time, the importance of effectively managing these areas with a single responsible organization in the organizational sense has been mentioned. In addition, it was stated that a data theme, such as the protected areas data theme in INSPIRE, should be defined in TNGIS.
