map2loop.thickness_calculator.InterpolatedStructure

class map2loop.thickness_calculator.InterpolatedStructure

Bases: ThicknessCalculator

This class is a subclass of the ThicknessCalculator abstract base class. It implements the thickness calculation method for a given set of interpolated data points.

thickness_calculator_label

A string that stores the label of the thickness calculator.

Type:

str

For this class, it is "InterpolatedStructure".

compute(units

pandas.DataFrame, stratigraphic_order: list, basal_contacts: pandas.DataFrame, map_data: MapData)

-> pandas.DataFrame

Calculates a thickness map for the overall map area.

Initialiser for interpolated structure version of the thickness calculator

__init__()

Initialiser for interpolated structure version of the thickness calculator

Methods

__init__()	Initialiser for interpolated structure version of the thickness calculator
compute(units, stratigraphic_order, ...)	Execute thickness calculator method takes unit data, basal_contacts, stratigraphic order, orientation data and DTM data to estimate unit thickness.
type()	Getter for subclass type label

compute(units: DataFrame, stratigraphic_order: list, basal_contacts: GeoDataFrame, structure_data: DataFrame, map_data: MapData) → DataFrame

Execute thickness calculator method takes unit data, basal_contacts, stratigraphic order, orientation data and DTM data to estimate unit thickness.

The method works by iterating over the stratigraphic order of units. For each unit, it finds the basal contact points and the top contact line. It then calculates the shortest line between these points. For each basal contact point, it finds the interpolated points that are within 10% of the length of the shortest line. It then calculates the true thickness of the unit at these points using the formula t = L . sin dip, where L is the length of the line orthogonal to both contacts and dip is the dip of the interpolated points. The method then calculates the median thickness and standard deviation for the unit.

Parameters:

• units (pandas.DataFrame) – the data frame of units to add thicknesses to

• stratigraphic_order (list) – a list of unit names sorted from youngest to oldest

• basal_contacts (geopandas.GeoDataFrame) – basal contact geo data with locations and unit names of

• contacts (the)

• structure_data (pandas.DataFrame) – sampled structural data

• map_data (map2loop.MapData) – a catchall so that access to all map data is available

Returns:

pandas.DataFrame – units dataframe with added thickness columns: “ThicknessMedian” is the median thickness of the unit, “ThicknessStdDev” is the standard deviation of the thickness of the unit

type()

Getter for subclass type label

Returns:

str – Name of subclass
