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

STAC Catalog

Geoconnex provides a STAC catalog of all the geospatial data contained in the graph here. Since it complies with the Portolan spec, it can be visualized in the browser here. This catalog contains both Parquet and PMTiles exports for each dataset.

Note that this is primarily focused on the geospatial data and some basic metadata like the name and description of the feature. While the JSON-LD source for the feature is provided in the geoparquet as a semi-structured jsonld column, 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.
