Data offered llm-inferred: building footprints (Microsoft Australia Building Footprints preferred, OSM/Overpass fallback) · building height and levels attributes (OSM) · obstruction heights from DSM-DTM elevation differences (optional, requires configured DSM and DTM) · 8-direction terrain profiles (N, NE, E, SE, S, SW, W, NW) · DEM-derived directional Mt topographic multipliers · directional terrain category evidence (built-up, vegetation, open terrain, obstruction density) · wind-region lookup from a local GA 1170.2 wind-region GIS file · VR, Md, Mz,cat and Ms lookup tables (digest-protected) · Vsit,b and Vdes,theta wind calculations
Coverage docs-verified: Australia (building sites; footprint and wind-region data depend on locally configured datasets)
Formats docs-verified: JSON · HTML · PDF · MCP (transport not specified)
Access docs-verified: Local install (wheel or source checkout). Licence per DOCS is commercial, but ENTRY lists AGPL-3.0, which conflicts and is unresolved. Production deployments must set the OPENWIND_RESULT_SIGNING_KEY environment variable (32+ bytes). No third-party API key is documented.

Use cases llm-inferred: Early wind site screening for a building project using directional terrain and topographic context · Terrain category evidence packs for structural or facade engineer review · Obstruction inventory with height provenance for shielding input review · Traceable preliminary Vsit,b and Vdes,theta calculations for AS/NZS 1170.2 screening
Audience llm-inferred: structural engineers · facade engineers · wind engineers · building consultants

Constraints llm-inferred: Pre-alpha maturity; not a certified design tool and does not produce certified design values · Does not assign final terrain categories or detect terrain transitions automatically · Does not produce certified Ms or certified topographic multipliers without engineer review · Public DEM data may not reflect survey levels, earthworks, retaining structures, vegetation or built obstructions · Needs locally prepared production datasets (Microsoft footprint cache, wind-region GIS file); bundled samples are test fixtures only · /health and openwind-au check report not_ready until production datasets, signing key and review metadata are configured · Vegetation is excluded from calculated shielding · Licence conflict: DOCS say commercially licensed, ENTRY says AGPL-3.0 · Maintenance risk: unreleased v0.8.0 milestone and an active pre-alpha codebase
