Netstar - Density Map

Kartoza was contracted by GeoInt to develop the Density Maps platform as a proof-of-concept tool designed to visualize the growth of newly introduced vehicle tracing products over time. Utilizing OpenLayers for visualization and Uber's H3 hexagonal grids for data aggregation, the platform ingests parquet-format data from an Amazon Blobstore into a PostgreSQL database. It generates dynamic views with pg_tileserv at multiple zoom levels, displaying information as a heat map. Users can filter and search data across various time series—days, weeks, or months—enhancing their ability to track product performance and growth effectively.
