Abstract :
Normalized Difference Vegetation Index (NDVI) has been widely used in evaluating the status and changes of ecological environment. This paper aims to introduce a method of extracting NDVI from image gained by HJ-1A/B CCD boarding on HJ-1A/B satellite. Cloud detection and atmospheric correction are carried out before the NDVI calculated. Results show that the NDVI can well describe the vegetation distribution.
