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")
