Downloading Geoconnex Graph Data Dumps

Geoconnex provides ways to download the entire graph database so that users can host or query it locally.

N-Quads​

Geoconnex provides a dump of all nquads that compromises the Geoconnex graph on github here. This is packaged as an OCI artifact. An OCI artifact is essentially a docker container for data that encapsulates a set of files with metadata. It can be easily versioned and rolled back.

You will need to install oras. oras is a command line tool for managing OCI artifacts. Then run oras pull to download the data.

Example​

Download the snapshot of the Graph generated on 2026_05_14

oras pull ghcr.io/internetofwater/geoconnex-graph:2026_05_14

Download the latest snapshot of the Graph

oras pull ghcr.io/internetofwater/geoconnex-graph:latest

Geoparquet​

Geoconnex also provides a download of all geospatial data in the graph as geoparquet here. Geoparquet is similar to CSV but binary encoded and more appropriate for large geospatial datasets.

Note that this is just the geospatial data and some basic metadata like the name and description of the feature. For other linked metadata such as dataset info that doesn't have direct geospatial data on it, you should make queries against the full graph database.
