Distantce to point - nearest point

[ARuggeri91]

Hi everyone,
I have a set of point with coordinate (latitude,longitude), and I want to identify which “B” points are the nearest to the “A” point whintin a buffer distance (e.g. 5 m)
Here an exemple of point.
Point
A 44.4475170 11.8266020
B 44.4473711 11.8263714
B 44.4475044 11.8267056
B 44.4474558 11.8267533
B 44.4475420 11.8266208
B 44.4473360 11.8264787
B 44.4473223 11.8264439
B 44.4474276 11.8265213
B 44.4473913 11.8264772

I tried to use the Palladian geonode using the haversine distance, but after obtaining partial difference between nodes, i don’t know how to continue the workflow.

Thank you everyone in advance.

Cheers

If I understand correctly, you only want to keep these entries which are below a given distance, which you obtain from the Palladian Geo Distances node?

You could simply go for a Row Filter node where you define a lower/upper bound:

Does this help?

Best regards,

Look here

Geo Distances Node

I'm new to KNIME and playing around with the Geo Distances node from Palladian. Can anyone explain how you're meant to use this? I would ehave expected it to take as input two pairs of Lat/Lon but it only appears to have input for one pair.

Thanks all the answer!
I arrived to this result (see image) with all the distances grouped in a set of number.

How can I continue to associate the point “B” point (identified with "MAN…) to the “A” point (identified with “8.03…”)
Thanks

Cheers

Hi,
are you looking for something like the Distance Matrix Pair Extractor?
Kind regards

@AlexanderFillbrunn yes is the node i was looking for!

Thank you very much!
