I imported a csv file as point feature. Selected longitude, latitude and z values as height. So my question is that when I do density based clustering, the program calculating the distance between points in 3 dimension or in 2d with just latitude and longitude variables.
I did this to multiple datasets and did scatter plot of clustered feature. I just could not be sure that distance calculation done in 3 dimension.
Any idea how the distance calculated?
This tool?

And if so, it is recommended that the coordinates used be in a projected coordinate system within certain ranges.
Chordal distances are used in any event
Yes, I agree with @DanPatterson on this, Projected Coordinate System is recommended for distance calculations.
Yes, this tool sir. I forgot to mention feature is projected.
I did read Density-based Clustering (Spatial Statistics)—ArcGIS Pro | Documentation but somehow I did not see the line, "This tool includes z-values in its calculations if z-values are present,. The result will be 3D." until you posted.
Thank you.
