Atmospheric aerosols have been associated with adverse health effects in areas of high concentrations. This is due to the ability of these sub-micrometer particles to penetrate further into the lung and alveoli for humans and animals. Besides this, aerosols are linked to have a significant influence on climate change and visibility. Therefore, it is important to have an effective technique to determine...
Aerosol optical thickness, AOT is one of the factors on determining air quality. The concentration of atmospheric aerosol is determined from radiances of image taken. On this study, we use AVHRR image which is appropriate to retrieve AOT from a wide coverage area. The methods of retrieving aerosol from visible and near-infrared radiance data were applied. The algorithm for mapping was based on dark...
Nowadays visual information becomes more and more important in almost all areas of our life. This information is represented and processed digitally. Digital image processing is ubiquitous, with applications ranging from television to tomography, from photography to printing, from robotics to remote sensing. In this study, we developed an algorithm to convert multispectral image pixel values acquired...
Nowadays, air quality is a major concern in many countries whether in the developed or the developing countries. Due to the high cost and limited number of air pollutant stations in each area, they cannot provide a good spatial distribution of the air pollutant readings over a city. Satellite observations can give a high spatial distribution of air pollution. The objective of this study was to map...
In this study, modern ICT and digital technology allow captured images to be transferred over Internet protocol to central monitoring centre. Internet protocol (IP) camera provides remotely and cost effectively monitor system. IP cameras also are flexible, powerful and wide ranging system applications. The objective of this study is to test the feasibility of using IP camera imageries for the particulate...
