Spatial information related to tourism can be collected, processed, organized and stored using tools such as GPS, GIS and RS. Based on the results of the cognition stage, data types were categorized in different formats and a conceptual model of a spatial database was developed. Then the descriptive information tables as well as the location field of each feature in PostgreSQL database were created and completed by PostGIS plugin, so the location of each feature can be displayed on the map (database geometry panel) and by selecting the feature on the map its descriptive information. is shown. The designed database allows access management, data control, backup, multiple users to use the database simultaneously, maintaining system integrity and finally the possibility of designing and implementing WebGIS system and its two-way communication with the user
