Study on Region Drought Inspection Using HighResolution ETM+Sensor Data
|
Abstract:
Land surface temperature can be used in the inspection of drought in the same vegetation index.In this paper, the principle of drought inspection using remote sensor was analyzed through thecharacteristic space of vegetation index and land surface temperature, land surface temperature wasreplaced with sensor temperature, the method of calculation drought index was discussed in detail. UsingLandsat7 ETM+sensor data in Luancheng County, the situation of drought was obtained and analyzed.
