Hello Roberto,
the input for the implementation should be ['time', 'x', 'y', 'feature_1', 'feature_2',...]
. Further, you should normalize all features features expect for the time.
If you want to use [lat, long]
values instead of [x, y]
you have to convert the values from the sphere to the plane. So I propose transforming the sphere coordinates to the utm coordinate system and inputting the data into the st_dbscan.
I hope that helps you.
Cheers, Eren
Hi there,
First, congrats for the great implementation of ST-DBSCAN. I'm evaluating using it for a research on spatiotemporal clustering of meteorological data (with multiple features). However, I have a question on your implementation:
An example of data point would be: on the first timestep, 300 is a specific city, x is latitude, y is longitude, feature 1 is precipitation, feature 2 is temperature, feature n is solar radiation: [0, 300, -23.5505, -46.6333, 1271.001, 28.763, 17.971]
Thanks a lot!
Roberto
