class sec_interp.core.services.structure_service.StructureService[source]

Bases: IStructureService

Service for projecting structural measurements onto cross-sections.

This service handles the filtering and projection of structural measurements (dip/strike) onto a cross-section plane to calculate apparent dip.

project_structures(line_lyr: qgis.core.QgsVectorLayer, raster_lyr: qgis.core.QgsRasterLayer, struct_lyr: qgis.core.QgsVectorLayer, buffer_m: int, line_az: float, dip_field: str, strike_field: str, band_number: int = 1) → list[StructureMeasurement][source]

Project structural measurements onto the cross-section plane.

Filters structures within a buffer, samples elevation, and calculates apparent dip for each measurement.

Parameters:

  • line_lyr – The cross-section line vector layer.

  • raster_lyr – The DEM raster layer for elevation sampling.

  • struct_lyr – Vector layer containing structural measurements.

  • buffer_m – Search buffer distance in meters.

  • line_az – Azimuth of the section line in degrees.

  • dip_field – Name of the field containing dip values.

  • strike_field – Name of the field containing strike values.

  • band_number – Raster band to use for elevation (default: 1).

Returns:

A list of StructureMeasurement objects sorted by distance along section.

Raises:
