Visualize points and routes with GeoJSON in Amazon Quick Sight layer maps
aws ·
Amazon Quick Sight has expanded its layer map capabilities to support Point and LineString geometries via GeoJSON files, allowing users to visualize specific locations and routes. While previous versions only handled polygon shapes for regions, the new update enables plotting individual store sites as points and tracing delivery paths or flight routes as lines. The article explains that these geometries are joined to datasets using shared keys, with distinct configurations for visualizing either points or lines in a single layer. A key distinction is made between native point maps, which auto-geocode data, and layer map points, which require explicit coordinates but offer precise viewport control. Advanced techniques described include locking the map viewport to prevent panning and zooming, and stacking multiple layer map visuals to combine different geometry types. For dynamic updates, the guide outlines how to programmatically refresh GeoJSON files using Amazon S3 and Quick Sight APIs rather than manual uploads. This enhancement supports complex business intelligence use cases such as tracking regional performance, monitoring logistics networks, and analyzing customer density within defined territories.
