The results show that: VBSI may decrease the error of vegetation fraction resulted from the area of image shadow, and the error is 50% less than that from NDVI.

研究结果表明：VBSI在估算山区的植被覆盖信息上可以降低影像阴影信息的干扰，总体误差是归一化植被指数NDVI 的50%；

However, there appear many problems in its application in forestry, such as the high price of data, the irremovability of image shadow, the low accuracy of quantitative estimation, etc.

但是高分辨率遥感影像在林业领域中的应用面临诸多问题，如数据源的价格偏高、图像阴影无法去除、树种识别困难和森林蓄积量估测精度不高等。

First is the HDR (High Dynamic Range) mode allowing the camera to capture three separate exposures and combine them in-camera for a stunning image capturing both enhanced shadow detail and bright highlights.
