Monitoring of vegetation coverage of Taiwan Island using SPOT imagery data

In this study, we used SPOT images over years of 2002 and 2003 each year covering two different seasons, to investigate the vegetation coverage over the whole Taiwan island. Attention was paid to evaluate the impacts of seasonal effects. Comparatively, the NDVI over the forested areas was stable, except the landslide sites. From this study, we can see that using the constellation of SPOT satellites to improve the observation frequency is essential to the useful monitoring of vegetation coverage.
