Abstract

Using an integrated Geographic Information System and remote sensing approach, this research investigates the Urban Environmental Quality (UEQ) of Salford, Greater Manchester. UEQ is difficult to measure directly so is determined using secondary variables. This research used seven variables representing/measuring different aspects of the built environment (building area, Normalised Difference Building Index and Surface Temperature) and green spaces (Normalised Difference Vegetation Index and proximity to water). A UEQ index was created from the variables using Principal Component Analysis (PCA) and four UEQ types were identified. Areas with high UEQ were typically characterised by large areas of green spaces, while those with low scores were characterised by a larger proportion of built-up space and taller buildings
