Research Interest
Medical and public health research reveal there are significant population suffering from seasonal allergy caused by pollen. Street trees are a major source of such allergen in New York City. NYC Department of Parks and Recreation has been organizing vunlenteers to measure and geo-tag all street trees, yet there is few study on how pollen by tree species having impact to local air quality. In this study we aim to visualize such risk in space (where in the city?) and time (which season?).
Methodology
I create this visualization based on NYC street tree census data in 2015. Based on our research on pollen active season and allergen severity, we further assign binary variable (1,0) for active seasons and categorical variable ('mild','moderate','severe') for allergen severity by each tree spcicies.
