Crate ifc_georef 

IFC project-to-map coordinate operations.

This crate resolves IFC references, units, axis defaults, and CRS metadata, then emits a format-neutral axiolid_core::Transform3. It does not place products, reproject coordinates, or select a geometry backend.

Modules

authoring

Transactional authoring of the georeferencing entities.

Structs

GeorefView

A model whose declared schema has been pinned to IFC4 or IFC4X3.

LengthUnit

A length unit reduced to a metre factor.

ProjectToMap

A resolved project-to-map coordinate operation, normalised to metres.

ProjectedCrs

A projected coordinate reference system read from IfcProjectedCRS.

Enums

GeorefError

Why a project-to-map operation could not be resolved losslessly.

NorthReference

A resolved north reference: a unit-length 2D direction in the project’s own XY plane, plus which reference it names.

Functions

compose_project_frame

Compose an externally supplied project frame with a resolved project-to-map operation, producing the project frame’s map-frame transform.

grid_north_direction

Resolve grid north from an already-computed IfcMapConversion operation.

project_north_direction

The project’s own north reference: always (0, 1) in its own XY plane.

resolve_project_to_map

Resolve an IfcMapConversion and normalize both frames to metres.

resolve_project_to_map_in

Resolve an IfcMapConversion within a schema-pinned GeorefView.

resolve_true_north

Resolve IfcGeometricRepresentationContext.TrueNorth.

Type Aliases

GeorefResult

Result of a georeferencing read, carrying GeorefError on failure.
