Community awareness plays a vital role in community development. In order to maintain awareness and address untoward incidents, a strong collaboration between authorities and its community should be built. This study presents the development of a community-based incident reporting and mapping system that serves as a tool for disseminating relevant public information, manage and monitor incident data, and visualize significant occurrences through geographical mapping and reporting using Google Maps Application Programming Interface (API). The method involves data visualization utilizing reverse geocoding approach to convert geographic coordinates to its actual city address and street names to display incident data markers on maps. Furthermore, to strengthen community engagement, the system provides functionality that enables individuals to confirm certain incident in their area allowing government agencies to monitor the validity of the incident. Results showed that city officials and society individuals found the said system to be useful to the community, especially to the participating government organizations to have a single, collaborative platform to coordinate with each other and improve their management tasks. Lastly, the findings illustrate that geographical visualizations and using color-coded incident markers on maps provide clear presentations of incidents enabling insights that can assist decision-making.
