I'll help you explore the geoconnex knowledge graph! Let me start by getting some basic information about it.
Perfect! Now I have a good understanding of the **GEOCONNEX** knowledge graph. Let me summarize what's available:
## GEOCONNEX Knowledge Graph
**GEOCONNEX** is an open, community-driven knowledge graph linking U.S. hydrologic features to enable seamless water data discovery, access, and collaborative monitoring.
### Key Statistics
- **19.2 million triples** describing hydrologic data
- **1.6 million hydrologic locations** including:
- Monitoring sites
- Dams
- Watersheds
- Stream networks
- Water bodies
- **763,000 point geometries**
- **320,000 polygon features**
### Main Feature Types
The knowledge graph includes:
1. **Hydrologic Features**:
- Catchments (watersheds)
- Flow paths and stream networks
- Hydrologic nexuses (junction points)
- Hydrometric features (monitoring stations)
2. **Water Body Types**:
- Streams, canals, ditches
- Estuaries and ocean features
- Lakes and water bodies
- Sinkholes
3. **Groundwater Features**:
- Wells
- Aquifer systems and units
- Hydrogeologic units
4. **Monitoring & Observations**:
- Sensor observations
- Hydrometric networks
- Measurement data
### What Can You Explore?
I can help you query this knowledge graph to:
- Find hydrologic features by location or name
- Explore watershed relationships (upstream/downstream connections)
- Discover monitoring stations and their observations
- Analyze catchment networks and drainage patterns
- Find geographic features and their geometries
- Explore groundwater systems
**What would you like to explore?** For example, I can help you find monitoring stations in a specific area, trace upstream/downstream relationships, or search for specific hydrologic features.

Perfect! Here's the GEOCONNEX knowledge graph schema visualization:

The diagram shows the core structure of the GEOCONNEX knowledge graph, including:
**Key Entity Groups:**
- **Catchments & Watersheds** - hierarchical relationships showing upstream/downstream connections
- **Flow Paths & Networks** - the stream and river networks
- **Hydrometric Features** - monitoring stations and observation points
- **Groundwater** - wells, aquifers, and hydrogeologic units
- **Location Types** - streams, canals, estuaries, subsurface features
- **Geometries** - points, polygons, and lines for spatial representation
The relationships show how water flows through the system, how catchments connect to each other, and how monitoring features relate to the hydrologic network.
