Building Cypher Query using spatial relations?

[xingchenc]

When I look closely at the supply chain demo shown at Esri 2022 developer summit(Plenary | 2022 Esri Developer Summit - Esri Videos: GIS, Events, ArcGIS Products & Industries), I noticed that inside the Cypher Query, it compares the spatial relationship between the two entities and returned the path that has the correct relationship(in this case, "Intersect").  

The capability to query entities using spatial relations is a huge bonus when extracting information from the Knowledge Graph. However, when I was looking for detailed explanations regarding how this is done in the ArcGIS Pro help, I found nothing. I was wondering if anyone know where should I look? 

@MeganBanaski1 Hi Megan, I was wondering if you have more information on this stuff?

@xingchenc Currently, supported spatial relation operators are esri.graph.ST_Equals(<geom>, <geom>), esri.graph.ST_Intersects(<geom>, <geom>), and esri.graph.ST_Contains(<geom>, <geom>).

For spatial utility, there is esri.graph.ST_GeoDistance(<geom>, <geom>) and for spatial construction there is esri.graph.ST_SKTToGeometry(string).

Hi Megan,

Thanks a lot, this is really helpful!

BTW, can you elaborate on the esri.graph.ST_SKTToGeometry(string) method?

Apologies there was a typo in there, it is esri.graph.ST_WKTToGeometry(string). It constructs a geometry from the OGC simple feature access well-known text format.

Thanks Megan!
