1. What is EnviroAtlas?
An online decision support tool giving users the ability to view, analyze, and download geospatial data and other resources; designed to inform decision-making, education, and additional research.
EnviroAtlas includes:
Geospatial indicators
Supplemental data (e.g., boundaries, land cover, soils, hydrography, impaired water bodies, wetlands, demographics, roads)
Analytic and interpretive tools

2. Interactive Mapping Tool
300+ map layers available online
National: Wall-to-wall coverage for contigous US; summarized by ~90,000 drainage basins (12-digit HUCs) data layers
Community: High-resolution component for 50 populated places; summarized by US census block group data layers.

3. Data are organized into 7 ecosystem service benefit categories.
Biodiversity Conservation
Clean
Air
Climate Stabilization
Recreation, Culture, & Aesthetics
Clean & Plentiful Water
Food, Fuel, & Materials
Natural Hazard Mitigation
Data are organized into 7 ecosystem service benefit categories.

4. Ecosystem Services & Health:
Unrealized Assets = Unintended Consequences
Approach: Demonstrate Multiple Benefits of Green Infrastructure,
Clean air
Clean & plentiful water
Natural hazard mitigation
Climate stabilization
Recreation, culture & aesthetics
Food, fiber & materials
Biodiversity conservation
…and How They Relate to Human Health & Well-Being
Air and water pollutants removed by neighborhood tree cover
Homes and schools near busy roadways
Extreme heat events
Opportunities for physical exercise, social engagement, outdoor experience, and play
Boiling it down: Hazard Buffering and Health Promotion

5. Land cover is an important input
Portland, OR

6. Community Information to Assist Decision-Making
e.g., health interventions, public infrastructure, social equity
Walking
Opportunities for physical activity, engagement with nature, & social interaction
Estimated reductions in adverse respiratory health events due to ambient air filtration by trees
Potential to improve school performance through cognitive restoration & stress reduction

I would change the black text on this slide to white text for better visibility.
That’s all I have time for today.
What I’ve shown you is just the tip of the iceberg of what we have available but I hope you have been inspired by the possibilities.
If you’re interested, please stop by and see more for a live demonstration of our tools. Thank you!
