Satellite Imaging-in-Industries

Satellites can be the only data source in rural and remote areas where no ground-based measurements are taken. A remote sensing technique was widely used for environment pollutant application such as air pollution. Some studies showed that satellite data could be useful for revealing climatic and environmental implications of global air pollution. Satellite data can aid in the detection, tracking, and understanding of pollutant transport by providing observations over large spatial domains and at varying altitudes. Satellite measurements clearly have the advantage of being the only set of measurements that provide a wide coverage. Landsat, SPOT, MODIS image data present a wide applicability for air pollution studies. Several studies have shown the possible relationships between satellite data and air pollution. The study of PM concentration usually based on spatial and temporal data series measured in ground station sites in cities and rural areas. Ground site measurements require high installation and maintenance costs. Furthermore, the data collected through these methods are effective only within the small spatial coverage around the station. So, the ground measurements cannot provide a detail spatial distribution of the particulate matter (PM) air pollutant over a large area. Satellite remote sensing has provided quantitative information on Particulate matter with acceptable accuracy comparable to that of surface measurements. MODIS images were widely used for monitoring, mapping and estimating of pm10 concentration. Due to the limitations of using MODIS data include coarse MODIS spatial resolution, variation of correlation coefficients between MODIS product and PM concentration depending on the location and weak correlation coefficients between MODIS product and PM concentration, air pollution researchers were looking for a more suitable satellite data. Visible and thermal bands of Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM7) were used widely for air pollution studies.
