Hi when u said Ndvi first one 10:45 does it mean first of all the elements? Means in first in time series?
Also I'm getting layer error: unable to transform edge.
Kindly help me with this

If I have training points in form of a shapefile which I have imported in gee, how do I get the pixels of these points and compute their average monthly NDVI if I am working with images of 5 years?

Sir
I want to compare NDVI from 2018 to 2022 but only for December month. how to filer imageries.

Nice video but I was confused starting from the NDVI aspect since am using MODIS (MYD09GA) and I want to calculate my NDVI, please how can I do that. Moreover, how can I perform cloud mask(clear cloud state=0) and Quality assurance QA (ideal quality = 0)?

Hello, just wanted to ask if this is also possible for NDWI? Especially for Sentinel 2.

Hello,
Thanks for this great video. I tried to replicate this but I keep getting the error message
"Collection.first: Projection error: Unable to compute intersection of geometries in projections SR-ORG:6974: affine [231.65635826395825, 0.0, -2.0015109354E7, 0.0, -231.65635826395834, 1.0007554677003E7] and EPSG:4326: affine [1.0, 0.0, 0.0, 0.0, 1.0, 0.0]." fter adding my shapefile as ROIs. How can i correct this please. Thanks
