This repository is a fork from an previous repository (which does not exist anymore), therefore I'm not the author of this code, I've only brought very tiny modifications.

ST-DBSCAN: An algorithm for clustering spatial–temporal data

Birant, D., & Kut, A. (2007). ST-DBSCAN: An algorithm for clustering spatial–temporal data. Data & Knowledge Engineering, 60(1), 208-221.

INPUTS :

data = spatio-temporal data
x = data longitude
y = data latitude
time = data timestamps

eps = distance minimum for longitude and latitude
eps2 = temporal window
minpts = number of points to consider a cluster
cldensity = TRUE or FALSE to display the number of points reachables for every point within a cluster

OUTPUTS :

data$cluster = cluster number
data$cldensity = cluster points density
