This video briefly elaborates on the most sought after Vegetation Index - The Normalized Difference Vegetation Index and it's relevance in real world scenarios. Additionally, a rudimentary case study was discussed where the index is estimated or forecasted using regression analysis.

Can this be performed on a time-series analysis where the datasets are not exactly around the same months across the chosen years? Like if the seasons are different, will the prediction still be accurate?

Not as accurate as it should be, though you can predict the general trend, it's advised to make sure your data is temporally matched first!

My attribute table has -9999 values? What might be the problem

It means that your pixel has no data in it, try changing the location of your point

Can you please make a video on how to collect data for NDVI? I do not have any Idea to collect data for NDVI

@cartogeospatialsolutions3890 11 месяцев назад

Sure, we'll give it a thought. Long story short, you just need to download NIR and Red bands for your aoi from a data provider like USGS

is necessary to add forests and if yes how do i get for a full study area

@cartogeospatialsolutions3890 7 месяцев назад

This is a case study to estimate vegetation density in forests, that's why I've used it. Yes of course you can download forest cover of any area from bbbike extracts

This equation ,how to interpreted ? if have some reference plz give a link

@cartogeospatialsolutions3890 3 месяца назад

It's a simple linear regression equation (y = a +bx) used to find a dependent variable's (y) value from an independent variable (x). There are lots of references online that describes this equation in depth
