Filter a linestring dataset to items within a polygon

[kletts]

I'm having trouble filtering a linestring dataset for items within a set polygon, the code I'm using is:

geo.filter(bike, { func: (d) => geo.within(d, gmel) }); 

where bike is the linestring (bike paths) and gmel is the polygon (a city boundary). The code is implemented in this observable notebook.

I notice that none of the examples in geo.filter show operations against another dataset, perhaps I'm misunderstanding the iteration, especially since the geo.within function is asynchronous.

Any suggestions? Thanks for a great package!

The geos functions are asynchronous and there are memory issues to deal with. I need to improve that. In the meantime, why not use:
withingmel = geo.clip(bike, { clip: gmel })

Perfect, thanks for helping me, clip is exactly right, silly me for not seeing it!
