The GeoVectors corpus is a comprehensive large-scale linked open corpus of OpenStreetMap entity embeddings that provides latent representations of over 980 million entities.

This repository contains the GeoVectors Framework that can be used to encode individual OpenStreetMap snapshots. For further information please visit http://geoemb.l3s.uni-hannover.de/

• Python >= 3.8

• Postgres DB with PostGIS

1. Clone the repository

git clone https://github.com/NicolasTe/GeoVectors.git
cd GeoVectors

2. Install the Python Requirements

pip install -r requirements.txt

3. Download the pretrained model

cd models/fasttext
./download.sh

Adjust the database credentials in the db.ini file.

Encoder.py [-h] [--db_cred DB_CRED] [--model MODEL] [--njobs NJOBS] input output modelPath
positional arguments:
  input              Input: directory containing OpenStreetMap snapshots to be encoded
  output             Directory to save encoded files
  modelPath          Path to pretrained model

optional arguments:
  -h, --help         show this help message and exit
  --db_cred DB_CRED  Credentials for the database
  --model MODEL      Name of the embedding model. Either fasttext or nle
  --njobs NJOBS      Number of threads to use

1. Download the specific OpenStreetMap snapshot you want to encode, e.g., from https://download.geofabrik.de/. We recommend using the osm.pbf format.

2. Run the tag embedding model:

python3 Encoder.py ./snapshots ./embeddings_tags ./models/fasttext --model fasttext

3. Run the NLE embedding model:

python3 Encoder.py ./snapshots ./embeddings_nle ./models/nle --model nle --db_cred db.ini
