geost.base.LayeredData.get_layer_top#

LayeredData.get_layer_top(column: str, values: str | List[str], min_thickness: float = 0, min_depth: float = 0)[source]#

Find the depth at which a specified layer first occurs, starting at min_depth and looking downwards until the first layer of min_thickness is found of the specified layer.

Parameters:
  • column (str) – Name of column that contains categorical data.

  • values (str | List[str]) – Value or values of entries in the column that you want to find top of.

  • min_thickness (float, optional) – Minimal thickness of the layer to be considered. The default is 0.

  • min_depth (float, optional) – Minimal depth of the layer to be considered. The default is 0.

Returns:

Borehole ids and top levels of selected layers in meters below the surface.

Return type:

pd.DataFrame

Examples

Get the top depth of layers in data where the lithology in the “lith” column is sand (“Z”):

>>> data.get_layer_top("lith", "Z")
