how do you crop / extract map data from .osm.pbf in the Julia programming language

My goal is to obtain the driving road network of a certain area using open street map data. Reference link: What's the general algorithm to draw a road network of a certain area? I'm using Julia package OpenStreetMapX. In the function call get_map_data, I realized that there is the other function OpenStreetMapX.crop!(osmdata, crop_relations = false). I understand that the purpose of this function is to crop the nodes, ways, relations based on a given bounds. I'm confused about these two different methods.

One Answer:

I had a quick look at the repo and there didn't seem to be a crop function to start with, see https://pszufe.github.io/OpenStreetMapX.jl/latest/reference/ Further I didn't see any PBF format support, just OSM xml format.

I would suggest asking the author for support as it is rather unlikely anybody here will be able to help you.

The crop function is here: https://github.com/pszufe/OpenStreetMapX.jl/blob/master/src/crop.jl The .osm file is supported as the following: using OpenStreetMapX map_data = get_map_data("/home/ubuntu/mymap.osm"); println("The map contains $(length(map_data.nodes)) nodes")

If just doesn't turn up in the documentation.
