2 years ago See the documentation:
tags (dict) – Dict of tags used for finding objects in the selected area. Results returned are the union, not intersection of each individual tag. Each result matches at least one given tag. The dict keys should be OSM tags, (e.g., building, landuse, highway, etc) and the dict values should be either True to retrieve all items with the given tag, or a string to get a single tag-value combination, or a list of strings to get multiple values for the given tag. For example, tags = {‘building’: True} would return all building footprints in the area. tags = {‘amenity’:True, ‘landuse’:[‘retail’,’commercial’], ‘highway’:’bus_stop’} would return all amenities, landuse=retail, landuse=commercial, and highway=bus_stop.

Hi Geoff, I have read the documentation, and searched on the internet (https://stackoverflow.com/) for solutions, but until now I didn't find any hint about how administrative boundaries are handled in osmnx. To give an example, I am trying to run this code: ''' tags = {"boundary":"administrative","admin_level":"4" } gdf =ox.geometries.geometries_from_bbox(51.5, 51.0, 11.7, 11.2, tags) gdf.shape ''' The bounding box seems to be used as a polygon to create an intersection with all the boundaries in the OSM database, the first tag is working because only administrative boundaries are returned, but the filter on level is ignored (checking with gdf["admin_level"].head() shows level 6).
I would like to understand what I am doing wrong, and how I can use this package better; it seems like a very useful library, and could submit a working example, if I have made a mistake in my code and have a map with the correct levels. Thanks, Gijs
