<div>Thanks for your reply, Mateusz.<br></div><div><br></div><div>I know (and use) Overpass turbo. However, what I want to do is to store a query and execute it in order to update results and store them as a file for further manipulation, so I can easily update results without the need to accessing to the interface, generate the query, run it and then download the results. I would like to achieve same functionallity but just by executing a file (which, additionally, may have more than one query).<br></div><div><br></div><div>So far, I found <a rel="nofollow" title="https://github.com/DinoTools/python-overpy" target="_blank" href="https://github.com/DinoTools/python-overpy">overpy</a>, which seems to work fine in terms of querying but has two problems for me: <br></div><ol><li>It seems to be unmaintained (last commit dates from April 2017)<br></li><li>I didn't succeed in storing the result into a geospatial file (or a geopandas data frame) (visit this jupyter lab with my current achievements: <a href="https://github.com/ccamara/osm-python/blob/master/overpy-demo.ipynb">https://github.com/ccamara/osm-python/blob/master/overpy-demo.ipynb</a>)<br></li></ol><div>I also have just found <a rel="nofollow" title="https://github.com/mvexel/overpass-api-python-wrapper" target="_blank" href="https://github.com/mvexel/overpass-api-python-wrapper">Overpass API wrapper</a>, but I still have to explore it and understand how does it work and how can I tame it to my needs.<br></div><div><br></div><div>You propose a third way, which is using overpass and writing a script.
