The Base GIS Field.
It's used as a base class for GeometryField and RasterField. Defines
properties that are common to all GIS fields such as the characteristics
of the spatial reference system of the field.
zThe base GIS field.FN�� Tc s* || _ || _||d< t� jdi |�� dS )a�
The initialization function for base spatial fields. Takes the following
as keyword arguments:
srid:
The spatial reference system identifier, an OGC standard.
Defaults to 4326 (WGS84).
spatial_index:
Indicates whether to create a spatial index. Defaults to True.
Set this instead of 'db_index' for geographic fields since index
creation is different for geometry columns.

or raster doesn't have an SRID, then the SRID of the field will be
returned.

The initialization function for geometry fields. In addition to the
parameters from BaseSpatialField, it takes the following as keyword
arguments:
dim:
The number of dimensions for this geometry. Defaults to 2.
extent:
Customize the extent, in a 4-tuple of WGS 84 coordinates, for the
geometry field entry in the `USER_SDO_GEOM_METADATA` table. Defaults
to (-180.0, -90.0, 180.0, 90.0).
tolerance:
Define the tolerance, in meters, to use for the geometry field
entry in the `USER_SDO_GEOM_METADATA` table. Defaults to 0.05.
