Overview

Kartoza developed a cloud-based proof-of-concept platform for GeoInt to process and visualise large volumes of telematics data, billions of points representing vehicle tracing activity. The system ingests parquet-format data into a PostgreSQL/PostGIS database, aggregates it using Uber’s H3 hexagonal grids, and serves the results as vector tiles through an API with heatmap styling.

Using OpenLayers for visualisation, the platform allows users to explore growth and performance over time with flexible time-series filtering (by day, week, or month). Dynamic, multi-zoom tile generation enables smooth navigation and detailed spatial analysis, helping GeoInt better understand usage patterns and track the success of their new vehicle tracking products.
