Thanks for sharing, it's helpful.

Beautiful
Thank you :)
Thank you so much, i'm going to try with Sentinel2
Cool :)
Great video indeed, wondering if it is possible to use the code on a small study area to represent NDWI time-series animation?
probaby caluclating NDWI from the sentinel 2, and stacking the collection to generate the timeseries might help, the process is similar. thanks!
great work! can we create this animation with other ee.imagcollection data sets? such as LAI from the GEE catalog. where we have a composite image of 4 days?
yes, the things will be the same, try changing the dataset.
Thank you. Works perfectly. Moreover, shows interannual changes.
Could you inform how to extract database? İ really appreciate
By database, if you mean spatio-temporal statistics (finding mean and others), there is tutorial in the earth engine tutorials, may be you can follow from there. OR may be I am not clear with your question. -Thankyou
@@ksabmagar7 sure. İ mean statistical data.
@@JDKSH25 Then check this, developers.google.com/earth-engine/tutorials/community/spatiotemporal-image-statistics
you can modify this for your use.
Hello, i am working on this and just when i was almost done i got an error: Image asset 'users/gena/fonts/Arial30' not found. How can i solve it
probably because something might be missing in your codes, please check line by line, thankyou
hello, teacher. Can we use NDVI in our glaciers study?
Hello, thankyou for the question. Firstly, I am not a teacher, but a learner like you.
As for the NDVI in glacier study, I am sure it is used as many of the parameters in modeling study. Please search the relevant literature, you will sure find the appropriate methodologies. -Thankyou
Can we print each of the time series imshes
Yes, we can. There is a function to do that getFilmstripThumbUrl.
Thanks!
@@ksabmagar7 Thank you
Is the script use here an open source code where can we get it
@@manglem10 yes you can, the resource is adapted from the earth engine guides. For what you were asking, there is the example for that too. developers.google.com/earth-engine/guides/ic_visualization#filmstrip -Thanks
Thank you very much for the effort!!!
I followed the steps as mentioned, however I am getting an error at the end stating: "A mapped function's arguments cannot be used in client-side operations." in the second last line "print(rgbVis.getVideoThumbURL(gifParams));"
This happens when server-side object and client-side object get mixed. There sure must have been some mixing unknowingly.
@@ksabmagar7 Getting a different error: List index must be between 0 and 0, or -1 and -1. Found 1. Any solutions?
@@ksabmagar7 managed to resolve it. Problem was with spelling in one of the lines. Thanks again!
@@katunduchabala7266 good to know. :)
