urkish National GIS (TNGIS) studies have been accelerated to standardize Turkish land administration after INSPIRE and LADM and to be a part of the e-Turkey transformation process. In the process, one of the geographical data sets transferred from the classical environment to e-government platforms is the protected areas. This study was carried out for a Specially Protected Environment Area (SPEA). The Göksu Delta has been determined as the study area. In the study, an interview form was used as a data collection tool. Then, the geographical data model design of the SPEA was carried out with UML schemes. The most important results obtained from the study are the necessity of preparing UML diagrams for all protected areas together with field experts and integrating them into TNGIS, and the necessity of using such protected areas under urban pressure in a more controlled manner in a dynamic structure with the GIS system.
