📍 command-line tool for clustering geolocations.
Project description
geoclustering
📍 command-line tool for clustering geolocations.
Features
- Uses DBSCAN or OPTICS to perform clustering.
- Outputs clustering results as
json
,txt
andgeojson
. - Creates a kepler.gl visualization of clusters.
Clustering Method
A cluster is created when a certain number of points (=> --size
) each are within a given distance (=> --distance
) of at least one other point in the cluster.
Install
Clone the repository:
git clone https://github.com/bellingcat/geoclustering
cd geoclustering
Install keplergl build dependencies:
# macos
brew install proj gdal
Install project with pip:
pip install .
Usage
Usage: geoclustering [OPTIONS] FILENAME
Tool to cluster geolocations. A cluster is created when a certain number of
points (--size) each are within a given distance (--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.
Input
Inputs are supplied as a .csv
file. The only required fields are lat
and lon
, all other fields are reflected to the output.
id,name,lat,lon

Output
If at least one cluster was found, the tool outputs a folder with json
, geojson
, text
and a kepler.gl html
files.
JSON
Encodes an array of clusters, each containing an array of points.
[
{
"cluster_id": 0,
"points": [
{
"id": 9,
"name": "Rosanna Foggo",
"lat": -6.2074293,
"lon": 106.8915948
}
]
}
]
GeoJSON
Encodes a single FeatureCollection
, containing all points as Feature
objects.
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
106.891595,
-6.207429
]
},
"properties": {
"id": 9,
"name": "Rosanna Foggo",
"cluster_id": 0
}
}
]
}
txt
Encodes cluster as blocks separated by a newline, where each line in a cluster block contains one point.
Cluster 0
