Arcade ExplodeSegments() function

Could an Arcade function be added that would explode geometries into separate lines for each segment?

That would be helpful when doing complex analysis on polyline segments.

@JohannesLindner @Thanks, what I meant was: explode a given polyline part into multiple 2-vertex segments (split at each vertex).

but then you would be getting into Arcade having different license levels

I don't know... Seems like a quite narrow use case to make a function for. Plus, you can easily do it yourself:

function explode_polyline(geo) { var segments = [] for(var p in geo.paths) { for(var q = 1; q < Count(geo.paths[p]); q++) { var point0 = paths[p][q-1] var point1 = paths[p][q] Push(segments, Polyline({"paths": [[point0, point1]], "spatialReference": geo.spatialReference})) } } return segments } Console(explode_polyline(Geometry($feature)))

@JohannesLindner Fair enough.

@KoryKramer, feel free to close. Cheers.

As noted, each segment can be obtained by looping through the vertices of the geometry.
