Using a Geo Distance Function on ELKI

我的梦境 提交于 2019-12-02 01:20:33

What is your epsilon value?

Geographic distance is in meters in ELKI (if I recall correctly); Manhattan distance would be in latitude + longitude degrees. For obvious reasons, these live on very different scales, and therefore you need to choose a different epsilon value.

In your previous questions, you used epsilon=0.008. For geodetic distance, 0.008 meters = 8 millimeter.

At epsilon = 8 millimeter, I am not surprised if the clusters you get consist only of duplicated coordinates. Any chance that above coordinates do exist multiple times in your data set?
