A Web and Mobile Geospatial Emergency Response Platform for Fire Incident Management Using Haversine-Based Proximity Dispatching
Year: 2026
Type: article
Abstract: Delayed dispatching, fragmented communication, and manually encoded records continue to hinder fire suppression operations in many developing regions. Philippine national statistics illustrate the magnitude of the problem: within the first half of 2024, authorities documented 14,894 fire occurrences nationwide with losses approximating PHP 5.71 billion, and Western Visayas registered the greatest regional share at 2,630 cases. This paper presents an extended account of the design, construction, and quality assessment of a unified geospatial emergency response platform built for the Bureau of Fire Protection (BFP) in Roxas City, Capiz. The platform pairs a browser-based command console, written in SvelteKit with TypeScript, with a Flutter mobile client through which residents transmit coordinate-tagged emergency reports. A dispatching engine anchored on the Haversine great-circle formula ranks candidate fire stations by spherical distance, after which the Google Maps Directions service resolves the fastest road-network path and projected arrival time. Live state propagation across every connected console is handled through Server-Sent Events (SSE), while Firebase Cloud Messaging (FCM) pushes severity-graded alarms that mirror the twelve-tier alarm taxonomy of the BFP. Construction followed iterative Agile sprints covering planning, backlog initialization, module construction, pilot release, and production hardening. Quality was appraised by ten evaluators, five Information Technology (IT) specialists and five fire service domain practitioners, against the eight characteristics of the ISO/IEC 25010 product quality model. The appraisal produced a grand mean of 4.53, an Excellent verdict, led by Security at 4.64, Portability at 4.63, and Usability at 4.58. These outcomes establish that the platform satisfies internationally recognized software quality benchmarks and offers a practical pathway toward shorter response intervals, coordinated multi-station dispatching, and stronger situational awareness for fire service organizations. This article extends the original conference paper presented in the BEST 2026 Proceedings Series with enlarged architectural documentation, the dispatching formulation, environment specifications, and criterion-level evaluation analysis.
