Hi,
I want to make a spatial joint of points with polygons. I loaded both shapefiles in Julia via GeoDataFrames.
Does the library allows for spatial join?
Thanks

FlexiJoins support optimized spatial joins of points - as in “find pairs of points within the specified distance” or “find the closest match in B for each point from A”.
But no optimization for polygon joins is available there, only the naive O(n^2)
looping approach. This is potentially in scope for FlexiJoins
, so feel free to propose an implementation that uses some optimized polygon lookup library. It shouldn’t be difficult, just isn’t in my own plans.
