jpd-defra opened a new issue, #1139:
URL: https://github.com/apache/sedona/issues/1139

   As per request from MoSarwat on the Sedona Discord channel, I'll open this 
issue.
   
   PostGIS has very useful function called `ST_LineLocatePoint `, which can 
provide the input value for the `ST_LineInterpolatePoint` function (already 
found in Sedona). 
   
   I'm wondering if anyone has the expertise to implement this function, as it 
would be very useful in snapping type workflows.
   
   I'm new to Sedona and wouldn't know how to start with a PR, but happy to try 
and help if I can. 
   
   The PostGIS docs are 
[here](https://postgis.net/docs/ST_LineLocatePoint.html).
   And an example of basic implementation in BigQuery can be found 
[here](https://www.linkedin.com/pulse/replicating-stlinelocatepoint-function-from-postgis-google-wrigley/).
