class pydriosm.reader._Reader(max_tmpfile_size=None, data_dir=None, downloader=None, **kwargs)

Initialization of a data reader.

Parameters:

max_tmpfile_size (int or None) – defaults to None, see also the function pyhelpers.settings.gdal_configurations()
data_dir (str or None) – directory where the data file is located/saved, defaults to None; when data_dir=None, it refers to the directory specified by the corresponding downloader
downloader (GeofabrikDownloader or BBBikeDownloader or None) – class of a downloader, valid options include GeofabrikDownloader and BBBikeDownloader
kwargs – [optional] parameters of the function pyhelpers.settings.gdal_configurations()

Variables:

downloader (GeofabrikDownloader or BBBikeDownloader or None) – instance of the class GeofabrikDownloader or BBBikeDownloader

Tests:

>>> from pydriosm.reader import _Reader

>>> r = _Reader()

>>> r.NAME
'OSM Reader'

>>> r.SHP
pydriosm.reader.SHPReadParse
