Satellite Infrared Remote Sensing Monitoring Indigenous Coke-Production in Northern China

In recent years, although the China government has carried out some serious investigation and effort to shut down the indigenous coke-production, it has not achieved effective control. The main image TM754 (red, green, blue) false color composite of Shanxi province in northern China was chosen as the study area in this paper. The indigenous coke-production sites are regions which appear red and yellow and the flag is obvious. The result showed that TM7 channel was the most sensitive to indigenous coke-production, TM5 channel was the second. TM754 band composite can be used to interpret indigenous coke-production sites with 94% accuracy identified by the ground check.
