[Community] multilinestring interpolate

[Kai Li]

Hello,

I'm using project() function to get the distance of nearest point along a
multilinestring, then use this distance in interpolate() function to find
the nearest point in the multilinestring. What's not as I expected is that
if the distance indicated is in the ending of a linestring, the
interpolate() function will always return the beginning point of next
linestring.
So, how can I easily find the nearest point with this kind of exception? Do
I need to write loops to project() and distance() on each linestring?

Regards,

Hello,

Can you tell us what your expectation is or what exactly you seek in this
function? Are you looking to get the ends of a particular segment instead
of the start of the next segment?
