The method for rapid extraction of vegetation supply water index: Using HJ-1B satellite data

摘要

Featured by high resolution and broad bandwidth, HJ-1B satellite data have great potential and wide application in the research of surface temperature inversion. However, in China products generated from remote sensing index data are rare, and how to quickly make remote sensing data products is an important issue. In this study we designed a processing method for calculating the vegetation water supplying index data with ERDAS. The results showed that this model can work very well in many researches as it has high accuracy and efficiency.
