Example

>>> # Loading Libraries and split data
>>> import gemgis as gg
>>> # Split Data - from get_meta_data_df(...)
>>> data = data.split()
>>> data = '#'.join(data)
>>> data = data.split('-Stammdaten')
>>> data = [item.split('|')[0] for item in data]
>>> data = [item.split('#') for item in data]

>>> # Filter out wells without Stratigraphic Column
>>> data = [item for item in data if 'Beschreibung' in item]

>>> # Get Coordinates of data
>>> coordinates = [get_meta_data(page=item) for item in data]
>>> coordinates[0]
