class pysgems.io.sgio.PointSet(project, pointset_path: Optional[str] = None, force_2d: bool = False)[source]

Bases: Package

__init__(project, pointset_path: Optional[str] = None, force_2d: bool = False)[source]

Handles the creation of a PointSet object.

Parameters

  • project – Project instance

  • pointset_path – Path to the pointset file

  • force_2d – If True, the pointset is forced to be 2D

export_01(features: Optional[list] = None)[source]

Gives a list of point set names to be saved in sgems binary format and saves them to the result directory

Parameters

features – Names of features to export

loader()[source]

Parse dataset in GSLIB format

pysgems.io.sgio.datread(file: Optional[str] = None, start: int = 0, end: Optional[int] = None)[source]

Reads space separated dat file

Parameters

  • file – path to the file to be read

  • start – start index

  • end – end index

Returns

numpy array of the data

pysgems.io.sgio.export_eas(dataframe: DataFrame, filename: str = 'dataset')[source]

Exports a Pandas DataFrame to geo-eas format

Parameters

  • dataframe – Pandas DataFrame to be exported

  • filename – name of the file to be written

pysgems.io.sgio.write_point_set(file_name: str, sub_dataframe: DataFrame, nodata: int = -999)[source]

Function to write sgems binary point set files.

The Simulacre_input_filter class is a filter that can read the default file format of GsTLAppli. The format is a binary format, with big endian byte order. Following are a description of the file formats for the pointset and the cartesian grid objects. All file formats begin with magic number 0xB211175D, a string indicating the type of object stored in the file, the name of the object, and a version number (Q_INT32). The rest is specific to the object stored:

  • point-set:

    a Q_UINT32 indicating the number of points in the object. a Q_UINT32 indicating the number of properties in the object strings containing the names of the properties the x,y,z coordinates of each point, as floats all the property values, one property at a time, in the order specified by the strings of names, as floats. For each property there are as many values as points in the point-set.

  • cartesian grid:

    3 Q_UINT32 indicating the number of cells in the x,y,z directions 3 floats for the dimensions of a single cell 3 floats for the origin of the grid a Q_UINT32 indicating the number of properties all the property values, one property at a time, in the order specified by the strings of names, as floats. For each property, there are nx*ny*nz values (nx,ny,nz are the number of cells in the x,y,z directions).

Parameters

  • nodata – nodata value, rows containing this value are omitted.

  • file_name – name of the file to be written.

  • sub_dataframe – Sub-frame of the feature to be exported [x, y, feature value]
