exception gws.gis.gdalx.Error

Bases: gws.Error

GWS error.

class gws.gis.gdalx.DriverInfo(*args, **kwargs)

Bases: gws.Data

Basic data object.

This object can be instantiated by passing one or or dict arguments and/or keyword args. All dicts keys and keywords become attributes of the object.

Accessing an undefined attribute returns None and no error is raised, unless the attribute name starts with an underscore.

gws.gis.gdalx.drivers() → list[DriverInfo]

Enumerate GDAL drivers.

gws.gis.gdalx.open(path, mode, driver: str = '', as_raster: bool = False, as_vector: bool = False, **opts) → DataSet

Open a path and return a vector DataSet object.

Parameters:

  • path – File path.

  • mode – ‘r’ (read), ‘a’ (update), ‘w’ (create for writing)

  • driver – Driver name, if omitted, will be suggested from the path extension.

  • type – ‘raster’ or ‘vector’ for dual drivers, like Geopackage.

  • opts – Options for gdal.OpenEx/CreateDataSource.

Returns:

DataSet object.
