Exploring MODIS time-series NDVI with Google Earth Engine

[@brentwilder1513]

Thank you this training was super helpful. I had some trouble with filtering the dates at first, however, found that GEE must have changed the format. But super easy fix. Thanks!!

Please help me out , I am not able to fix it

[@brentwilder1513]

@@vandanachoudhary7348 I can't recall why this wasn't working for me. But as a workaround I have been using the following method for the past year and is working well for me (copy and paste below). Let me know if this works for you . Make sure to substitute in the path to the image collection he is using here // Import image collection var data = ee.ImageCollection('path/to/image/collection') .filter(ee.Filter.date('2000-01-01', '2021-07-01'))

[@Hala_1238]

please where i can find this titorial written i mean the link or resource i need it to practice

Hi, I'm trying to get a time series of NDVI from MODIS/061/MOD13Q1 and the NDVI value I get is from 5500 to 7000. is it correct?because in the video, your ndvi value is between -1 to 1.

[@sherzodzaitov8588]

Hi, thanks for very good guidance. Can you tell is it possible to get this pdf manual? If yes where? Thank you from the advance

[@sheldonfranklin7423]

can the script be used with landsat-7 TOA

[@sveabertolatus2139]

thank you for the info! one question: since we calculte ndvi over time, it it the change in ndvi for each cell that is displayed on the map, or is it one of the values?

How to get the numerical data from the chart?

[@IAKhan-km4ph]

Amazingly done

[@IAKhan-km4ph]

Dear Sir, I have tried this, Time series graph is working on the region or with polygon, but not working with shape file, plz guide me in this.

[@gj3933]

My question is: has anyone compared the NDVI results computed in GEE with that from GIS software? Are they consistent?

[@williamfarren4734]

could someone clarify something for me? is the ndvi on the y axis of the timeseries a mean taken of the all ndvi within the polygon? please and thank you

Please help me do a NDWI for modis

[@AbhishekKumar-sx7oe]

Sir....help me in smoothing long time series evi or ndvi data usi g moving average or double logistic model

[@TheGREATtyk]

please how can we access the script?

[@piusawhari9531]

very interesting lecture sir. can we have the code

NO ME SALE EL SCRIP =(

[@christopherwilliams_7]

Thanks for the video and for share pdf Google training. This is very same to MODIS time series land surface temperature. Regards!
