queryRenderedFeaturesInRect gives back empty featurecollection

[peterbodo]

I use a mapbox street based basemap and want to query places appearing on the map.

const handleOnPress = async ( pressedPoint: GeoJSON.Feature ): Promise<void> => { const center = (pressedPoint.geometry as GeoJSON.Point).coordinates; console.log(center); const features = await mapViewRef.current?.queryRenderedFeaturesInRect( [ center[0] - 0.01, center[1] - 0.01, center[0] + 0.01, center[1] + 0.01, ], null, [ "poi-scalerank1", "poi-parks-scalerank1", "poi-scalerank2", "poi-parks-scalerank2", "poi-scalerank3", "poi-parks-scalerank3", "poi-scalerank4-l1", "poi-scalerank4-l15", "poi-parks_scalerank4", ] ); console.log(features); };

Like this. The map clearly have these layer ids rendered, but I got back empty Featurecollection.
Why is that?

Note: same with empty array for bbox.

Thx a million :)

and eeerrr... where are my line breaks in the code part?

It might be totally unrelated, but after fighting with a similar issue for whole day I noticed, that at least queryRenderedFeaturesAtPoint requires position in pixels, instead of coordinate, despite documentation mentioning explicitly - A point expressed in the map view’s coordinate system. Didn't checked that, but It might be also case for queryRenderedFeaturesInRect

const results = await map.queryRenderedFeaturesAtPoint( [ PixelRatio.getPixelSizeForLayoutSize(x), PixelRatio.getPixelSizeForLayoutSize(y) ] )

In my case x/y is location of crosshair on screen and I'm querying features at onCameraChanged. I needed explicitly calculate pixel position.
I hope this helps.

Just now checked and yes, it's same with queryRenderedFeaturesInRect

[peterbodo]

Thanks a million. That is very useful indeed, if I progress with the basic problem.
But...
It doesn't work for me either with [] as bouding box, which should be the map view.
I have made a bug report on this:

[mikelsis]

Yeah, queryRenderedFeaturesAtPoint and queryRenderedFeaturesInRect feels quite tangled.
You can workaround issue with [], by creating bbox using screen size, but proper fix from maintainers would be appreciated.

[peterbodo]

Just tested and it works. Thx!!!!

Thank you for this! The documentation led me astray for hours before discovering this discussion. I've confirmed that pixels are the expected value on my end too. Hopefully the maintainers update the docs.

Make a quick PR to update the docs if you like. I'm sure it would be appreciated.
