π command-line tool for clustering geolocations.
- Uses DBSCAN or OPTICS to perform clustering.
- Outputs clustering results as
json
,txt
andgeojson
. - Creates a kepler.gl visualization of clusters.
A cluster is created when a certain number of points (defined with --size
) each are within a given distance (defined with --distance
) of at least one other point in the cluster.
Install with pip:
# with kepler.gl visualization support
pip install geoclustering[full]
# only text-based output
pip install geoclustering
If the full
install fails, you might need to install kepler.gl build dependencies:
# macos
brew install proj gdal
Usage: geoclustering [OPTIONS] FILENAME
Tool to cluster geolocations. A cluster is created when a certain number of
points (defined with --size) each are within a given distance (defined with
--distance) of at least one other point in the cluster. Input is supplied as
a csv file. At a minimum, each row needs to have a 'lat' and a 'lon' column.
Other rows are reflected to the output.
Options:
-d, --distance FLOAT (in km) Max. distance between two points in
a cluster. [required]
-s, --size INTEGER Min. number of points in a cluster.
[required]
-o, --output PATH Output directory for results. Default:
./output
-a, --algorithm [dbscan|optics]
Clustering algorithm to be used. `optics`
produces tighter clusters but is slower.
Default: dbscan
--open Open the generated visualization in the
default browser automatically.
--debug Print debug output.
--help Show this message and exit.
Inputs are supplied as a .csv
file. At a minimum, each row needs to have a lat
and a `lon`` column. Other rows are reflected to the output.

If at least one cluster was found, the tool outputs a folder with output as json
, geojson
, txt
, csv
files. A kepler.gl html
file is generated as well.
Encodes an array of clusters, each containing an array of points.

Encodes a single FeatureCollection
, containing all points as Feature
objects.

Encodes cluster as blocks separated by a newline, where each line in a cluster block contains one point.
Cluster 0

Encodes each event in one line with cluster_id
information associated.
