There is nothing special about using YSLD here, so I am assuming the issue with with the function PointN.
Q: What geometry are you working with here? A multi-point? Q: Why are you getting the second point, do you mean poinN(geometry,0) instead? The function is here: - https://github.com/geotools/geotools/blob/master/modules/library/main/src/main/java/org/geotools/filter/function/FilterFunction_pointN.java - https://github.com/geotools/geotools/blob/master/modules/library/main/src/main/java/org/geotools/filter/function/StaticGeometry.java#L336 Reading the code : - It assumes the first geometry is a linestring, and will return null for anything else - it wants number between 0 ... number of points (so 0 is indeed the first point) -- Jody Garnett On Wed, 17 Jun 2020 at 02:20, 4harry4444 <4harry4...@gmail.com> wrote: > Hi Everyone! > > I would like to confirm if somebody tried to use the PointN function in > YSLD.
