gempy.core.data.Topography

class gempy.core.data.Topography(_regular_grid: RegularGrid, values_2d: ndarray, FieldInfo(annotation=NoneType, required=True, exclude=True)] = <factory>, source: str | None = None, resolution: Tuple[int, int]=FieldInfo(annotation=NoneType, required=False, default=(0, 0), init=True))

Object to include topography in the model. .. rubric:: Notes

This always assumes that the topography we pass fits perfectly the extent.

Methods

classmethod from_subsurface_structured_data(structured_data: subsurface.StructuredData, regular_grid: RegularGrid)

Creates a topography object from a subsurface structured data object

Parameters:

structured_data (subsurface.StructuredData) – Structured data object

Returns:

gempy.core.grid_modules.topography.Topography

classmethod from_unstructured_mesh(regular_grid, xyz_vertices)

Creates a topography object from an unstructured mesh of XYZ vertices.

Parameters:

• regular_grid (RegularGrid) – The regular grid object.

• xyz_vertices (numpy.ndarray) – Array of XYZ vertices of the unstructured mesh.

Returns:

gempy.core.grid_modules.topography.Topography

set_values(values_2d: ndarray)

General method to set topography

Parameters:

values_2d (numpy.ndarray[float,float, 3]) – array with the XYZ values in 2D

Returns:

gempy.core.grid_modules.topography.Topography

set_values2d(values: ndarray) → Topography

Reconstruct the 2D topography (shape = resolution + [3]) from a flat Nx3 array (or from self.values if none is provided).

property topography_mask

This method takes a topography grid of the same extent as the regular grid and creates a mask of voxels

__init__(_regular_grid: RegularGrid, values_2d: ndarray, FieldInfo(annotation=NoneType, required=True, exclude=True)] = <factory>, source: str | None = None, resolution: Tuple[int, int]=FieldInfo(annotation=NoneType, required=False, default=(0, 0), init=True)) → None
