Introduction
At Curve Metrics, we specialize in transforming complex operational challenges into streamlined, intelligent digital solutions. While our expertise spans various domains, our work in Geographic Information Systems (GIS) represents a powerful fusion of real-time data, geographic intelligence, and actionable insights. This capability allows businesses to move beyond simple tracking to achieve unprecedented control over their mobile assets and field operations.
Our approach is not just about placing dots on a map; it’s about creating a central nervous system for logistics, compliance, and fleet management. Here’s a deep dive into our projects that showcase how we’ve implemented this vision for our clients.
1. Project: SMS Envocare Limited (Pan-India)
Sector: Medical Waste Management
The Challenge: SMS Envocare, a leader in bio-medical waste management, faced a critical operational and compliance hurdle. Their fleet of waste collection vehicles operates under stringent government regulations that mandate strict adherence to predefined routes and timely disposal. Any deviation from the assigned path or unauthorized stoppage could lead to significant regulatory penalties, safety hazards, and environmental risks. They needed a robust system to enforce geographic discipline and receive immediate alerts for any anomalies.
Our Solution: We designed and developed a comprehensive Real-Time GIS Tracking and Alerting System with sophisticated geofencing logic.
- Core Architecture: The system was built on a scalable cloud-based backend, integrating with GPS devices installed in each vehicle. The front-end features an intuitive dashboard with an interactive map built using Leaflet.js.
- Intelligent Geofencing: For each vehicle and its daily schedule, we programmed multiple types of geofences:
- Primary Route Corridors: Defining the acceptable geographic path for collection.
- Client Location Geofences: Circular zones around hospitals and clinics for pickup verification.
- Treatment Facility Geofences: Ensuring waste is delivered only to the authorized Common Bio-medical Waste Treatment Facility (CBWTF).
- Alert Mechanism: The system continuously monitors vehicle movement against these virtual boundaries. The moment a vehicle deviates from its corridor or lingers outside a geofence for a configured duration, it triggers a multi-channel alert:
- In-App Dashboard Alerts: Visible to all logistics managers.
- SMS Notifications: Sent directly to the designated fleet manager’s phone for immediate attention.
- Email Reports: Detailed reports for audit trails and compliance records.
- Technical Stack: Node.js backend, React.js frontend, PostgreSQL with PostGIS extension for geographic data handling, and integration with Twilio API for SMS alerts.
The Impact: This solution provided SMS Envocare with real-time oversight, drastically reducing compliance risks and enabling proactive management of their fleet. It brought transparency to their operations and created a verifiable digital record for regulatory audits.
2. Project: Kisan Fresh Logistics (Nashik, Maharashtra)
Sector: Perishable Goods & Agriculture Logistics
The Challenge: Kisan Fresh transports temperature-sensitive produce like grapes and berries from farms to export hubs and domestic markets. Their major challenge was “first-expiry-first-out” logistics and preventing spoilage. Deviations from the planned route or unexpected delays at non-refrigerated checkpoints could lead to entire consignments being rejected, resulting in massive financial loss.
Our Solution: We implemented an Integrated IoT and GIS Monitoring Platform.
- Core Architecture: We integrated IoT temperature sensors in the refrigerated containers (reefers) with the existing GPS trackers. This data was fed into our central GIS platform.
- Dynamic Geofencing & Route Optimization: Beyond static geofences, the system used APIs to pull data on traffic conditions and suggest optimal routes in real-time to minimize transit time.
- Condition-Based Alerts: The system was configured to trigger alerts based on a combination of geographic and environmental factors:
- Alert 1: If the vehicle deviates from the optimized route.
- Alert 2: If the internal temperature of the reefer moves outside the predefined safe range (e.g., 2°C – 4°C for berries), regardless of location.
- Alert 3: If the vehicle is stopped for more than a pre-set time (e.g., 30 minutes) at a non-designated location, potentially indicating a breakdown or unauthorized stop.
- Technical Stack: Python (Django) backend, Vue.js frontend, MongoDB for handling high-frequency sensor data, and integration with Mapbox APIs for advanced mapping visuals.
The Impact: Kisan Fresh achieved a significant reduction in spoilage rates, enhanced the quality of delivered produce, and improved their reliability with export partners, directly boosting their bottom line.
3. Project: Metro Water Authority (Chennai, Tamil Nadu)
Sector: Public Utility & Water Management
The Challenge: The city’s water tanker fleet, responsible for supplying water to drought-affected areas, was plagued by inefficiency. There was no transparency in routes, leading to allegations of missed deliveries, unauthorized water sales, and an inability to respond dynamically to emergency requests.
Our Solution: We built a Public-Facing Water Tanker Tracking Portal.
- Core Architecture: A dual-platform system with an admin dashboard for dispatchers and a public-facing, mobile-friendly tracking portal for citizens.
- Transparency through Geofencing: Each neighborhood or “ward” was mapped as a geofence. When a tanker entered a ward, its status on the public map would update to “In-Progress.” Once it left, the status changed to “Completed.”
- Dynamic Dispatch: Dispatchers could see all tankers on a live map. In case of an emergency request from a new area, they could quickly identify the nearest available tanker and assign the job digitally, defining a new geofence for the task.
- Accountability Metrics: The system automatically generated reports on total water delivered per area, time spent, and completion rates, eliminating manual logbooks and bringing accountability to the process.
- Technical Stack: Laravel (PHP) framework, MySQL database, and Google Maps JavaScript API for its robust public mapping features.
The Impact: The system restored public trust, optimized water distribution based on real-time need, and eliminated operational ambiguities, ensuring help reached the areas that needed it most.
Our Technical Philosophy in GIS Projects
Our approach to GIS development is built on three pillars:
- Precision Engineering: We use robust stacks like PostGIS for complex geospatial queries and calculations, ensuring accuracy and performance.
- Actionable Intelligence: We believe data is useless without insight. Our systems are designed to not just show data, but to analyze it and trigger precise, actionable alerts.
- Scalability & Compliance: Our solutions are built on cloud architectures that can grow with your business and are designed with Indian regulatory and infrastructural realities in mind.
Whether it’s ensuring hazardous waste is handled responsibly or that fresh produce reaches its destination in perfect condition, we are committed to building technology that delivers tangible, real-world value.
