Sns.Spatial is the reusable spatial layer for SnS. Its purpose is to keep spatial DTOs, provider options, provider interop, and map utilities separate from app state, EF data access, and SnS-specific workflows.
The project contains provider-neutral geo DTOs and GeoJSON DTOs, plus provider-specific folders. Google is the clearest current provider implementation, including DTOs, JavaScript interop, and static web assets under the spatial project.
Sns.Spatial should remain lightweight and reusable. It should not own authorization, database queries, feature state, or host application composition. Those concerns belong in Sns.Framework, DataMine.Models, or host applications.
