The environment and vegetation cover in mining area are influenced by the exploitation and utilization of mineral resources. It needs dynamic monitoring and estimation by the help of satellite remote sensing technology. Taking SPOT-VGT NDVI as information source and considering the characteristics of mining areas in China, this paper researched how to monitor the vegetation variation and desertification...
By the help of remote sensing techniques, urban growth of Shenyang was monitored. On the one hand, multisource and multi-temporal images were classified into two classes, built-up area and non-built-up area. Then urban expansion was depicted clearly during the past 28 years. On the other hand, NDVI data from 1999 to 2007 were processed to indicate the change of vegetation, which would be affected...
The phenomenon of a satellite thermal infrared (TIR) anomaly before earthquakes has been reported since the late 1980s. The reported increase of surface temperatures reaches 2-4 degC, occasionally higher. Usually, the anomaly appears one month to several days before the earthquake. Several mechanisms of hypothesis have been put forward to interpret the reported temperature increase. In this paper,...
