How to construct intersecting point between two lines with ArcGIS Arcade?

Woodpeckerus

I need to construct a point on the intersection of 2 lines. How can I do that with Arcade? 

Intersects() basically return either a boolean or a feature that intersects, which is no good for my case. 

Intersection() doesn't seem to be able to return a point geometry? In my case, Intersection() will return a feature with null geometry - assuming the geometry would need to be a polygon in this case? 

Am I missing something really obvious here? 

Thanks

You're on the right path, Intersection() works when you're working with 2 individual geometries, whereas in your instance it's 1 geometry with a collection (even though your collection is only 1 intersecting geometry)

I suggest digging into the resulting intersects result using: 

var intersectsResult = Intersects($feature, otherLayer);

if (Count(intersectsResult) == 1) {
    // Run Intersection and the result will be the intersecting point geometry
    var intersectingPoint = Intersection($feature, Geometry(First(intersectsResult )));
} else {
    // There's more than 1 intersecting line, do nothing
    return null;
}

 

If you do want to work with multiple intersecting lines, using a for loop() will allow you to cycle through the results and work with each intersecting point geometry like line 5.
