FeatureLayer geometry filtering

JB19 — Tue, 14 Feb 2023 08:55:27 GMT

Hello everyone,

I'm working with Arcgis JS API 4.25.
I'm trying to filter a FeatureLayer based on this concept:
Apply effects to features

Since I'm using a SceneView, I can't use featureEffect.filter so i'm using filter directly on the featureLayerView, and it seems to work just fine.

The issue I have is with the buffer. The example works fine

But when I try to replicate it, there is this strange gap between the visual of the geometry and the actual geometry used to filter the features:

I'm doing nothing more than the example do :

Do you have any ideas what would be the problem ?
I'm guessing maybe something wrong about a wkid ?

It's a guess. Please let me know if it helps:

Since it works, but not at the right area,

maybe it is worth to use - await geometryEngineAsync.geodesicBuffer

What is the spatialReference of your map/scene ? Did you try using geometryEngine.geodesicBuffer instead of geometryEngine.buffer ?

I found what was the issue.
I was using this as a filter :

featureFilter = { geometry: bufferGeometry, spatialRelationship: spatialRel, distance, units: unit, };

But the bufferGeometry was already at distance from the initial geometry (filterGeometry).
So using a distance around the bufferGeometry was wrong.
I should have used :

featureFilter = { geometry: bufferGeometry, };

Such a dumb mistake ...
Thanks for your time.
