Experimental

Compute origin-destination cost matrix between point pairs. Calculates travel distance or cost along network paths.

## Parameters

Name | Description | Required | Default
--- | --- | --- | ---
`input` | Input line network layer. | Required | `network.shp`
`origins` | Origin point layer. | Required | `origins.shp`
`destinations` | Destination point layer. | Required | `destinations.shp`
`snap_tolerance` | Optional node snapping tolerance for graph construction. | Optional | —
`max_snap_distance` | Optional max distance from origin/destination points to nearest network node. | Optional | —
`edge_cost_field` | Optional numeric line field used as an impedance multiplier for segment length. | Optional | —
`one_way_field` | Optional line field marking one-way digitized edges (true/1/yes means from first to second vertex only). | Optional | —
`blocked_field` | Optional line field marking blocked/closed edges to exclude from routing (true/1/yes blocks). | Optional | —
`barriers` | Optional barrier point layer; nearest network nodes are blocked from traversal. | Optional | —
`barrier_snap_distance` | Optional max distance from each barrier point to a network node for blocking. | Optional | —
`turn_penalty` | Optional additive cost applied to non-straight turns at network nodes. | Optional | —
`u_turn_penalty` | Optional additive cost applied to U-turn transitions. | Optional | —
`forbid_u_turns` | If true, disallow U-turn transitions. | Optional | —
`forbid_left_turns` | If true, disallow left-turn transitions. | Optional | —
`forbid_right_turns` | If true, disallow right-turn transitions. | Optional | —
`turn_restrictions_csv` | Optional CSV of turn transitions using columns prev_x,prev_y,node_x,node_y,next_x,next_y. Optional columns: forbidden (default true when no turn_cost column is provided) and turn_cost (or penalty/cost/extra_cost) for per-turn additive cost. | Optional | —
`temporal_cost_profile` | Optional CSV defining time-dependent edge costs (columns: edge_id,dow,start_minute,end_minute,value). | Optional | —
`temporal_edge_id_field` | Optional network field used to match temporal_cost_profile edge_id values (default EDGE_ID). | Optional | —
`departure_time` | Optional RFC3339 departure time used for temporal profile lookup. | Optional | —
`temporal_mode` | Optional temporal interpretation mode: multiplier or absolute. | Optional | —
`temporal_fallback` | Optional fallback when temporal row is missing: static_cost or error. | Optional | —
`temporal_profile_report` | Optional JSON output path for temporal profile diagnostics (coverage, unmatched edges, fallback usage). | Optional | —
`output` | Output CSV path. | Required | —

## Examples

Creates an OD cost matrix from origins and destinations on a line network.

    wbe.network_od_cost_matrix(destinations='destinations.shp', input='network.shp', origins='origins.shp', output='od_matrix.csv')
