| May 28, 2016 at 13:14 | comment | added | thibautg | I think I found the problem: it's because ST_LocateAlong implementation in Spatialite returns NULL when the searched m_value is not on a specified vertex (search LocateAlongMeasure on gaia-gis.it/gaia-sins/spatialite-sql-4.3.0.html ). This is different than PostGIS's implementation which interpolates the measure between the two vertices around it. | |
