[Community] Line_Locate_Point

[Alfredo Alessandrini]

Hi,

I'm looking for a Python function equivalent to this:
http://postgis.net/docs/ST_Line_Locate_Point.html

Is there any library that I can use (shapely, ....)?



Thanks,

Alfredo

Hi Alfredo,

That linear referencing method is the 'project' method[1], which has a
'normalized' argument with a default of False to return the length
along the line. Setting normalized=True will return the fraction, just
as ST_LineLocatePoint does.
