The GREENER Geospatial Data Science Platform

GREENER bridges the gap between raw geospatial data and actionable research. We curate, process, and link decades of environmental exposure data to research cohorts.

Transforming raw environmental data into actionable, easy-to-understand insights.

A Curated Library of Environmental Exposure Data

GREENER maintains a continuously growing catalog of standardized environmental and social datasets — from satellite-derived air quality and greenspace indices to federal vulnerability and housing indicators. Every dataset is harmonized to CONUS census geographies and validated for spatial and temporal completeness before publication.

Secure, Institutional-Grade Geocoding

Participant addresses are geocoded entirely on-server within Mount Sinai's institutional infrastructure — no protected health information leaves our network. Each address is resolved to a precise coordinate and can be matched to any standard geography — census tract, block group, block, or ZCTA — or used directly for point-level residential extraction. Every geocoded record includes a match score, match type, and quality flag for transparent downstream QC.

From Participant Address to Linked Exposure Dataset

GREENER links participant cohorts to multiple environmental exposure layers simultaneously — air quality, greenspace, social vulnerability, climate, wildfire smoke, and more. Linkage is performed at the census tract level or at residence-level resolution, depending on the dataset and your study design.

Define Any Study Area, At Any Scale

Researchers can define their geographic area of interest by drawing a polygon, entering a bounding box, or selecting standard geographies — state, county, ZIP code, or census tract. Extraction is available at multiple spatial resolutions, from ZCTA-level aggregates to fine-scale grid exposures.

Transparent Data Quality, Every Delivery

Every dataset delivery includes a complete data dictionary documenting variable definitions, units, and sources. Cohort linkage requests also include a match rate report and QA flag columns. Temporal gaps, geographic mismatches, and missing values are documented before data leaves the platform — so your methods section reflects the actual state of the data.

How GREENER Works

From Participant Address to Linked Exposure Dataset

A secure, four-step pipeline — run on institutional infrastructure

Step 1 — Submit Your Cohort

Submit Your Participant List

Upload a de-identified participant list with address fields through your secure GREENER account. The platform deduplicates records, flags formatting issues, and prepares the data for on-server geocoding. No protected health information is transmitted or stored externally.

Step 2 — Geocoding & Geography Assignment

Secure Geocoding & Spatial Assignment

Addresses are geocoded using the Mount Sinai institutional GIS deployment. Each participant is matched to a geography (e.g. census tract, zip code, or custom polygon) and assigned a match score and quality flag. The geocoding process is entirely server-side and produces no outbound data transfer.

Step 3 — Select Your Exposures

Browse & Select Datasets

Explore the GREENER Data Library and add datasets to your request cart. Choose from air quality, vegetation indices, social vulnerability, climate, and built environment indicators. Specify the years, temporal resolution, and spatial aggregation level that fit your study design.

Step 4 — Receive Your Linked Dataset

Delivery with Full Documentation

Your request is processed by the GREENER team and delivered as a CSV or Apache Parquet file. Every delivery includes a data dictionary, match rate report, QA flag columns, and metadata describing the source, processing steps, and spatial resolution of each variable.

Step 5 — Analyze & Publish

Accelerate Your Research

By abstracting away the complex geospatial joins and harmonizing diverse datasets, GREENER enables you to move directly to statistical modeling and visualization. Build reproducible pipelines and accelerate your environmental health research.

Browse, Filter, and Download Environmental Data

No cohort required — explore and retrieve any dataset directly

Step 1 — Browse Library

Browse the Data Catalog

Looking for specific environmental indicators? Start your journey in the Data Catalog. Search across multiple categories from air quality to greenspace and select exactly what you need without needing to upload participant information.

Step 2 — Refine Results

Filter by Category

Not sure where to begin? Use our comprehensive filter system to quickly narrow down robust datasets based on environmental themes, societal vulnerabilities, climate indices, and customized categories built specifically for environmental health access.

Step 3 — Geographic Selection

Define Your Study Area

Constrain massive nationwide datasets to just the region relevant to your research. Whether you're targeting specific counties, bounding box coordinates, or an imported custom grouping, dynamically scope the spatial delivery of your chosen data.

Step 4 — Temporal Settings

Set Temporal Range

Fine-tune the time window of your query. Access historical trends alongside daily granular snapshots. Pick the temporal resolution your statistical approach demands — from multi-decade aggregated views, to high-resolution monthly variation maps.

Step 5 — Immediate Delivery

Download Packaged Dataset

Skip the waiting period. Get instant access to clean, research-ready data bundles. Complete with accompanying data dictionaries, metadata files, and comprehensive coverage reports, so you can focus entirely on uncovering analytical insights.
