Does Apache Sedona use pyproj for coordinate transformations or does it use other tools? I don't know if this is possible in Apache Sedona, but I did not see ST_Transform handle custom transformations between coordinate systems. I do not mean custom coordinate systems, i mean custom transformations. When running function St_transform(geometry, EPSG:From, EPSG:To, **Transformation EPSG**) I should be able to control which transformation to use between the two datums using a parameter **EPSG Code/WKT**. For example: St_Transform(geometry, (From) 4258, (To)4326, (Using) 1612 ) Why is this important? There are many ways to transform between to geodetic datums and this can have a huge impact on the accuracy of the end coordinates. In this case, if I do not control how the coordinate system transformation happens the accuracy can be tens of meters because there are roughly 36 ways to go from EPSG:4258 to EPSG 4326. This is not exposed to the end user at all. Whilst controlling which transformation to use, in this case 1612, the accuracy will be around 1 meter. Any way this can be exposed to the end user? -- This is an automated message from the Apache Git Service.
