Bases: odbind.survey._SurveyObject

A class for an OpendTect 2D seismic dataset

property comp_names: list[str]

list[str]: Names of components in this seismic dataset (readonly)

property line_names: list[str]

line_info(forlinenms: list[str] = []) → dict

Return basic information for all or a subset of lines in this 2D dataset.

Parameters

forlinenmslist[str]=[]

(Optional) a list of line names to use. For an empty list information for all lines in the dataset is provided.

Returns

dict

line_info_dataframe(forlinenms: list[str] = []) → dict

Return basic information for all or a subset of lines in this 2D dataset as a Pandas DataFrame.

Parameters

forlinenmslist[str]=[]

(Optional) a list of line names to use. For an empty list information for all lines in the 2D dataset is provided.

Returns

Pandas Dataframe

getdata(linenm: str) → tuple

Read the data for the given linenm

Reads all components and various supporting data and returns a tuple of: - a numpy array for each seismic component - a Python dict with information about the data

The information dict has the following keys and data: - ‘comp’: list[str] of the seismic component names - ‘line’: str of the line name - ‘trc’: np.ndarray(int) with the trace numbers - ‘ref’: np.ndarray(float) with the SP numbers - ‘x’: np.ndarray(double) with the x coordinates of the traces - ‘y’: np.ndarray(double) with the y coordinates of the traces - ‘twt’ | ‘depth’: list[float] with the Z start, stop and step (in display units) - ‘dims’: list[str] dimensions of the trace data

Parameters

linenmstr

line name to read

Returns

tuple : list[np.ndarrays], one array per seismic component and info dict

as_xarray(data: list[numpy.ndarray], info: dict)

Convert data returned by getdata method to Xarray Dataset

Parameters

datalist[np.ndarray]

seismic data for each of the components, in trc, z axis order

infodict

as returned by the getdata method, at minimum require ‘trc, ‘xline’ and ‘twt|depth’ fields

Returns

Xarray.Dataset
