Methods of Land Use Regression (LUR) modeling and Ordinary Kriging (OK) interpolation have been widely used to offset the shortcomings of PM2.5 data observed at sparse monitoring sites. However, traditional point-based performance evaluation strategy for these methods remains stagnant, which could cause unreasonable mapping results. To address this challenge, this study employs 'information ent...

Impervious surface area (ISA) is an important parameter for many studies such as urban climate, urban environmental change, and air pollution; however, mapping ISA at the regional or global scale is still challenging due to the complexity of impervious surface features. The Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) data have been used for ISA mapping, but...

This paper discusses the importance of determining an accurate depiction of total population and specific sub-population distribution for urban areas in order to develop an improved “denominator,” which would enable the calculation of more correct rates in GIS analyses involving public health, crime, and urban environmental planning. Rather than using data aggregated by arbitrary administrative...

Chronic obstructive pulmonary disease (COPD) is a major and increasingly prevalent respiratory health problem worldwide the fine particulate matter (PM2.5) now becoming rising threat to it. This study aims conduct comparison analysis of effect on acute exacerbation COPD (AECOPD) associated with PM2.5 exposure in two typical cities (Beijing Shenzhen) different levels pollution. Both correlationa...

This study aims to investigate geo-referenced vehicular noise pollution in Port Harcourt metropolis of Rivers State, Nigeria. Three types data were gathered for this study. Data from traffic measured decibel (dB) using Noise Dosimeter (ND); counts carried out by observing and counting flow at junctions roundabouts as well location map was established Global Positioning System (GPS) instrument p...

The level of concentration heavy metal in soil is detrimental to groundwater quality Sharada and Bompai industrial areas. A total 40 sampling points were selected from both two digested samples analysed for As, Cd, Cr, Cu, Co, Ni Pb using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-OES) machine. Geographic Information Systems (GIS) was used model present the spatiotemporal chan...
