Should def. param. values be selected,even if my scene contains other vegetat. types?

[rese_support]

Since the current LAI and FPAR equations are simple empirical relationships based on the selected vegetation index (either NDVI or SAVI) they can only approximate typical trends. This application is mainly intended to get the correct trends in multi-temporal studies, therefore it is recommended to use the same parameter set for all multitemporal scenes, whether it is the default or user-specified parameters. A quantitative agreement with field measurements of different crop types in different seasons cannot be expected.
