Reading layers
______________

.. code-block:: python

    from girs.feat.layers import LayersReader
    lrs = LayersReader('D:/tmp/DEU_adm_shp/DEU_adm4.shp')


Ambiguous suffixes require the parameter drivername 

.. code-block:: python

    from girs.feat.layers import LayersReader
    lrs = LayersReader('D:/tmp/DEU_adm.mdb', drivername='PGeo')

Available methods in LayersReader:

.. code-block:: python

    from girs.feat.layers import LayersReader
    lrs = LayersReader('D:/tmp/DEU_adm_shp/DEU_adm4.shp')
    for m in dir(lrs):
        if not m.startswith('__'):
            print m
