_Map geometries to environmental semantics_

`geoenv` is a Python library that maps geospatial geometries, such as points and polygons, to environmental terms in vocabularies/ontologies (e.g. [ENVO](https://sites.google.com/site/environmentontology/)). It’s like reverse geocoding, but for environments.

## Features

- **Broad scale environmental context:** Provides consistent broad scale environmental context supplementing local scale environmental descriptions.  
- **Global Coverage**: Provides worldwide resolution of terrestrial, coastal, and marine environments.  
- **GeoJSON Output:** Outputs data as a GeoJSON Feature, for integration with other tools and libraries.  
- **Concurrent Data Resolution:** Leverages `asyncio` to query multiple geospatial data sources concurrently, providing fast results.
- **Modular and Extensible**: Designed with a modular architecture to facilitate integration of new data sources and vocabularies.

## Quick Start

Install from PyPI:

```bash
$ pip install geoenv
```

Resolve a point location to environmental descriptions:

```python
import asyncio
from geoenv.geometry import Geometry
from geoenv.resolver import Resolver
from geoenv.data_sources import (WorldTerrestrialEcosystems,
                                 EcologicalMarineUnits,
                                 EcologicalCoastalUnits)

# Define a geometry in GeoJSON format (Point or Polygon)
geometry = Geometry(
    {
        "type": "Point",
        "coordinates": [
            -122.622364,
            37.905931
        ]
    }
)

# Set up the resolver. When the location's environment is not known, 
# multiple data sources are included to cover potential environment 
# types.
resolver = Resolver(
    data_source=[
        WorldTerrestrialEcosystems(),
        EcologicalMarineUnits(),
        EcologicalCoastalUnits(),
    ]
)

# Resolve the geometry to environmental descriptions. The resolver 
# queries multiple data sources concurrently using `asyncio`.
response = asyncio.run(resolver.resolve(geometry))

# Access response data.
print(response.data)
```

The response is a GeoJSON `Feature` with environmental terms mapped to [ENVO](https://sites.google.com/site/environmentontology/) (by default). Only resolved environments are included:

            "uri": "http://purl.obolibrary.org/obo/ENVO_00000080"
          }
        ]
      }
    ]
  }
}


```

## Motivation

Finding datasets based on their environmental context is a challenge in data synthesis. The process often relies on vague or inconsistent metadata. This variability presents a barrier to reliable, large-scale analysis due to time lost in data discovery and incomplete search results.

`geoenv` helps address this challenge by using a dataset’s originating location as a consistent and objective starting point. It can programmatically map the geometry of this location to standardized environmental terms, providing a scalable and repeatable method for generating interoperable metadata. This approach aims to enrich datasets with uniform, semantic metadata, making them potentially easier to discover, query, and integrate at scale.

## Related Projects

The [Global Ecosystems Atlas](https://globalecosystemsatlas.org/) is a project that provides a comprehensive, harmonized open resource on the world's ecosystems. It standardizes diverse geospatial datasets by mapping them to the [IUCN Global Ecosystem Typology](https://global-ecosystems.org/), a hierarchical classification of environments.
