Detailed Description

Spatial frame — CRS specification and coordinate data for nodes/links.

The spatial frame encapsulates the coordinate reference system (CRS) and georeferenced coordinates of nodes, link centroids, and subcatchment centroids. This is a new addition in version 6.0.0 that prepares the engine for 2D coupling.

2D Coupling Readiness (R30)

The SpatialFrame is designed to serve as the interface point for future 2D component coupling. A 2D SWMM component will register ICouplingPoint objects that map 1D nodes/links to cells in the 2D mesh.
