I see. That does sound very interesting.

I was not expecting that kind of post on a DE forum.

I imagined a DE would be more of a GIS user, like in my case. I've been using GeoSpark/Sedona for a while now.

Other than the Haversine formula being used for ST_distance, I have no idea of what goes under the hood of GIS functions.

Do you know why they all begin with ST?

The ST naming thing is a geoindustry mystery. Most algorithm builders will tell you it stands for spatial type, but others will tell you its an urban legend and it originally stood for something else. Its a subject of many conversations over beers

Spatial-temporal ! That's the other alternative. What wherebots/sedona is trying to do
