(Re)Detecting & (Re)Examining Heat Vulnerability Index (HVI)

Inspired by McHarg’s Ecological Method in natural geographic research, the methodology in producing HVI indices use layered transparency mapping with the integration of nature and built environment factors. Utilizing multiple geographic information software and algorithms, the research fi rst examines heat exposure based on LANDSAT land cover data, and then examines heat sensitivity with data provided in Census and American Community Survey. This poster illustrates how the research combines these two factors with four different geospatial methodologies, which are Principle Component Analysis (PCA), ISO Clustering, Anselin Local Moran’s I, and Natural Break Reclassifi cation. The poster also refl ects data performance and characteristics of each indexing methodology and the distribution of HVI across the New York City.
