Not sure about the ArcGIS implementation because I’ve only ever used OSS GIS tools, but usually ST_Distance is highly dependent on the SRS in use. If you ask ChatGPT about ST_Distance and what SRSs it returns miles for, it knows it is often more complicated. But it often gets these sorts of details wrong when generating specific SQL queries.

Have you ever used QGIS? If so . . . thoughts? Any other, quality OSS GIS you might recommend?

Yes, we use QGIS instead of Arc for basic GIS debugging and manipulation. My non-technical partners and employees use it to manipulate shape files to make them compatible with formats we support for imports etc. And I regularly use QGIS to help understand random GIS data we get. It lets me overlay GIS data on a Google Map base layer very easily which is often helpful.

Most of the GIS stuff we do uses programming libraries that leverage gdal/ogr/proj - basically the same stuff QGIS is built on.

We also use MySQL and its limited spatial functionality. We use PostGIS and SpatiaLite too. SpatiaLite can be a great way to get a lot of data into QGIS in a form that can be queried pretty efficiently.

The interface reminds me of ESRI and ERDAS stuff so I think I'll dive into it. Thanks for reminding me that there is a FOSS for everything.
