Hi,

Is there an equivalent to PostGIS' ST_LocateAlong for QGIS expressions yet?

https://postgis.net/docs/ST_LocateAlong.html

SELECT ST_AsText(the_geom)
                FROM
                (SELECT ST_LocateAlong(
                        ST_GeomFromText('MULTILINESTRINGM((1 2 3, 3 4 2, 9 4 3),
                (1 2 3, 5 4 5))'),3) As the_geom) As foo;

                                                 st_asewkt
-----------------------------------------------------------
 MULTIPOINT M (1 2 3)


We have line_interpolate_point but it does not take measure values into
account:

function line_interpolate_point

Returns the point interpolated by a specified distance along a linestring
geometry.


Thanks and best wishes,

Anita
