Hello from Yuhan Sun, Ph.D. student from ASU, US

I am a 5th-year PH.D. student at Arizona State University, US. My research focus is on database systems, spatial data, graph data.

Hello and welcome! :slight_smile:
I imagine you've seen this, but Neo4j does support a spatial data type:

and there's examples of how it works with OpenStreetmap too

Thanks for the information. I was using the spatial extension package of neo4j. But it seems the spatial index is inherently integrated into the neo4j main features now.
