Paper Abstract

Drought is one of the major environmental disasters in China. With the development of geographical information system and remote sensing technology, the real time monitoring drought over the large areas can be achieved. In this paper, the modified apparent thermal inertia (ATI) method was applied to monitor the drought while the traditional method was mainly used in bare soil and sparse vegetation. Taking Hebei plain as the study area, this paper calculated the apparent thermal inertia of all pixels firstly, and then got the 1km resolution classification result aggregated from 30m CCD data of HJ-1 satellite. Through analyzing the fine resolution classification result, the pure pixels were mask and the apparent thermal inertia was calculated. At last, the ATI values of all pixels were interpolated from the ATI of pure pixels via ARCGIS software. The application of the model to the announcement from Meteorological Bureau has given consistent results.
