Urban Morphology

The Urban Morphology panel turns processed street segments into a graph, generates morphological tessellations around buildings, and wires the building/street relationship graph used in urban form analysis.

Segments to graph

Converts a processed segments object (see Process Segments in Data Import) into a graph.

Control	Description
Segments → Graph	Select the processed segments object, then build the graph.

Tessellation

Generates a morphological tessellation (parcel-like cells) around selected buildings.

Control	Description
Shrink Factor	Morphological tessellation shrink factor (0-1).
Segment Length	Discretization segment length for the tessellation boundaries.
Generate Tessellation	Select the buildings (and optional barrier objects), then build the cells.

Morphological graph

Select the buildings + street network, then run Morphological Graph.

Control	Description
Center from OSMnx	Use the active OSMnx graph’s center. Disable to set Center Latitude / Longitude manually.
Analysis Radius (m)	Radius of the analysis area around the center.
Clipping Buffer (m)	Extra buffer around the area to avoid edge effects.
Contiguity Rule	Adjacency rule for cells: Queen (share edges or vertices) or Rook (share only edges).
Keep Buildings / Keep Segments	Preserve those geometries in the result.

Relations to include

Relation	Meaning
Private ↔︎ Private	Adjacency between tessellation cells (parcel neighbors).
Public ↔︎ Public	Connectivity between street segments.
Private ↔︎ Public	Interface (façade) between parcels and street segments.

Note

Enabling all three relations produces a single coherent heterogeneous graph (faster, uses the high-level builder). Enabling a subset wires only the requested relations and produces one Blender object per active relation type. At least one relation must be enabled.
