3-30-300 Tree Mapping
3-30-300 Tree Analyzer How green is your neighborhood? Urban forestry researchers have long known that access to nature directly impacts our mental health, local temperatures, and climate resilience. To turn these benefits into actionable urban planning targets, Cecil Konijnendijk proposed the 3-30-300 rule . The formula is simple but ambitious: everyone should be able to see at least 3 trees from their window, every neighborhood should achieve a 30% tree canopy cover, and every citizen should live within 300 meters of a high-quality public park or green space. As soon as I stumbled across the 3-30-300 rule this week, I knew it would make a perfect spatial analysis project. OpenStreetMap already crowdsources tree points and park boundaries worldwide, making it the ideal open data stack to map exactly which neighborhoods meet the rule and which ones are missing trees and easy access to green spaces. By combining OpenStreetMap data with on-the-fly spatial analysis, my 3-30-300 T...
