Abstract:
A web processing service based on Open Geospatial Consortium (OGC) web processing service (WPS) specification was designed and shared by the open source network geospatial information system platform 52°North to figure out the problems of temperature vegetation drought index (TVDI) including complicated calculation and repeat to achieve.TVDI model algorithm was realized using the Python language programming.The MODIS data in 2010 in Hubei Province were used to test the algorithm.The results showed that the ensemble of dry and wet edges linear fitting was good.The operation of algorithm was stable with high efficiency.The release and sharing of TVDI WPS avoided the problems of complicated calculation and repeat to achieve.It will help the researchers to focus on analyzing/studying the dry and wet conditions,and improve the efficiency of study.
