# sec_interp.core.validation.project_validator module

Validation for QGIS project state and layer presence.

sec_interp.core.validation.project_validator.validate_reasonable_ranges(values: dict[str, Any]) → list[str]

  Check for unreasonable or potentially erroneous parameter values.

  This function does not return hard errors, but a list of warning strings to inform the user about extreme values (e.g., vertical exaggeration > 10).

  Parameters:

    values – Dictionary containing parameter names and their current values.

  Returns:

    A list of warning messages. If empty, all values are reasonable.

class sec_interp.core.validation.project_validator.ProjectValidator

  Bases: `object`

  Orchestrates validation of project parameters independent of the GUI.

  static validate_all(params: ValidationParams) → bool

    Perform a comprehensive validation of all project parameters.

    Parameters:

      params – The parameters to validate.

    Returns:

      True if all checks passed.

    Raises:

      ValidationError – If any validation check fails.

  static validate_preview_requirements(params: ValidationParams) → bool

    Validate only the minimum requirements needed to generate a preview.

    Parameters:

      params – The parameters containing at least raster and line layers.

    Returns:

      True if the core preview can be generated.

    Raises:

      ValidationError – Description of missing core components.

  static is_drillhole_complete(params: ValidationParams) → bool

    Check if required fields are filled if drillhole layers are selected.

  static is_dem_complete(params: ValidationParams) → bool

    Check if DEM requirements are met.

  static is_geology_complete(params: ValidationParams) → bool

    Check if geology requirements are met.

  static is_structure_complete(params: ValidationParams) → bool

    Check if structural requirements are met.
