Hello, It is really great work that you are doing, I was just wondering if we can refine it more to get individual species of plant cover ? and what kind of satellite imagery would be required for it

How did you decide the ranges for shrubs versus other vegetation? Do trees and grass generally have a higher NDVI?

Hey! I am an urban planning student, therefore i use these data as a user. Do you use Radiometric Calibration on each bands' central wavelength? And do you think its necessary or not considering i am an urban planning student and not geodesy student

Can we clip NDVI data(after creating) only to our study area? or we need to make it seperately? you showed study area later with clipped NDVI. how to do it if i dont want to repeat the whole process but want to clip it only to my study area?
@GISRSSolution4 жыл бұрын
Its very simple. You can clip your study area before the operation or after as well. Just go to spatial analyst tool, then Extraction, Extraction by Mask.. You may watch the following video how to extract study area from Image kzbin.info/www/bejne/gH6qp6B6mrxkY5I

How did you get threshold value for waterbody, land ?
@GISRSSolution4 жыл бұрын
NDVI values are ranging from -1 to 1. Very low value of NDVI corresponds to barren areas of rock, sand, snow, cloud etc. Moderate values represent shrub and grassland while high value indicates temperate and tropical rainforests. Bare soil is represented with NDVI values which are closest to 0 and water bodies are represented with negative NDVI values. You can classify following the NDVI classes; -1 = Water Body 0 = Bare Soil, Rock, Sand and Snow, Cloud 0.2-0.3 = Shrub and Grassland 0.3-0.5 = Sparse and Unhealthy Forest >0.5 = Dense and Healthy Forest Hope it will help you. Thank you.
