LOCAL GOVERNMENT UNIT 3: BARANGAY MAPPING WITH INTERACTIVE MODEL USING OPEN STREETMAP

Abstract

Barangays, the smallest administrative units in the Philippines, often lack accurate, up-to-date maps that are critical for effective governance. This project addresses that gap by developing an interactive barangay mapping system for Local Government Unit 3 (LGU 3), aimed at improving planning, resource allocation, and community engagement. Utilizing Geographic Information System (GIS) technology and open-source tools such as OpenStreetMap, the system promotes data-driven decision-making and participatory governance. The project was developed using the Agile Scrum methodology to ensure continuous iteration and user-centered design. Data was collected through surveys, local government records, and geospatial sources. The system follows a microservices architecture for scalability and modular functionality. Mapping features were implemented using QGIS and OpenStreetMap, allowing real-time interaction, spatial data visualization, and administrative control. DevOps practices and CI/CD pipelines were adopted for efficient deployment and updates. The interactive mapping system enabled barangay officials and residents to access detailed spatial information, including infrastructure, population distribution, and available resources. Users could navigate maps through zooming, layer filtering, and data querying. The system provided better visibility into service delivery gaps, development priorities, and emergency preparedness. Initial stakeholder feedback indicated improved awareness of local issues and stronger community participation in planning activities. The project demonstrated the effectiveness of GIS and open-source mapping tools in enhancing local governance. It improved transparency, planning efficiency, and citizen engagement. However, challenges were noted in data validation, staff training, and long-term system maintenance. Despite these challenges, the system serves as a model for other LGUs seeking to adopt digital governance tools and supports the Sustainable Development Goals (SDGs) related to building sustainable communities and strengthening institutional capacity.
