Configurable GIS Data Model¶
The transition from an internal ad-hoc system to a reusable B2B product required a more flexible model for layers, geometry, and business metrics.
Solution: Designed a relational/PostGIS-based data model that allowed configurable GIS layers and binding of GeoJSON geometry to business attributes and indicators.
This made it possible to describe map layers not as hardcoded screens, but as configurable business objects.
