Public Participation Geographic Information Systems (PPGIS) have become essential tools for engaging citizens in urban planning and decision-making. However, a significant challenge persists in the temporality of data collection, most PPGIS platforms rely on one-time surveys or questionnaires, leading to outdated and infrequent data updates. This research proposes an innovative social media-based PPGIS that fosters continuous engagement, ensuring real-time and dynamic citizen participation. Unlike conventional methods, this approach integrates a location-based social media platform that allows citizens to contribute data through posts, discussions, and feedback mechanisms. Additionally, a recommender system will be developed to enhance interaction by prioritizing user-generated content based on location, relevance, and engagement history. The research will employ a mixed-methods approach, combining system development, usability testing, and participatory evaluation. Expected outcomes include an improved engagement model, enhanced real-time data collection, and a sustainable participatory environment for urban governance. This study aims to revolutionize PPGIS frameworks by bridging the gap between spatial decision-making and social media engagement.
