Thank you for the great online lecture. I have one question in mind. When we rely on remotely sensed data in inferring vegetation health status, how can I tell the unhealthy vegetation conditions were inducd by drought conditions and not by other factors, such as plant disease, infection, pollution, etc, since vegetation indices will give the same response/info on both cases (stressed vegetation)?
Alright, I got the answer to my question during the 21 Jan webinar. Thank you Mr. Tobias for the response. Appreciated.
