It's a wonderful recording. But I have a query related to ROI. So if I want the shapefile of British Columbia or Vancouver what will be the FeatureCollection code ?

Great work! So informative and detailed thank you so much for this!!!

Best tutorial so far with detailed working. Sometimes people hide some of the steps in the video, and that's create confusion when you try to implement the same thing. I have one question why you have choose band b4, b3, b2, b8 for classification? Is it true for all kindof classification using sentinel images. Which bands we can use in case of landsat8 data

Thanks. I chose bands 4, 3, 2 and 8 since they are the highest resolution (10 meter). You can apply similar band combinations for Landsat 8.

awesome video. i got a question, i've got an preprocessed shape with possible areas of pine plantation in brazil, i just i'd like to run a classification to verify inside these polygons wethers it's pine or not. Is there a way to transform a shapefile in FeatureCollection for then use it as my ROI? thanks again

Gracias!! :)

Very nice video! I an having some query I want to extract only urban class but while creating the different classes the Urban class mixed with the Barren class.kindly help me for the same.

Great video sir, how to export confusion matrix?

Thank you again for wonderful tutorial. I have one question is it possible to get the satellite map in Google earth engine in historic period like google earth pro?

This is great!! Can you please share the code in the comments?

Hi dear admin, Please may I ask you: when I zoom the google earth engine interface imagery, the ground fearures look like pretty clear and visible, but when I use your algorithm to make true color composite imagery to download, but at that time the ground fearures could not clearly visible? What is this problem and how to solve it ? I will be thankful for your valuable guidance about it.

Hi, can someone please help me with this code error: Cannot read property 'sampleRegions' of undefined. 34th minute of the video. I tried exactly as it was given but its not working.

Hi dear Admin. When I run this code: //Overlay the point on the imagery to get trainingDataset var trainImage = imput.sampleRegion({ collcetion : training, properties: [lable], scale: 30 }); then this error appeared: "Line 90: imput is not defined" Please tell me how to handle this issue?

Could you please explain the reason for using only Band 2, 3, 4 and 8 for classification?. It's on line 22, under the comment //Creating Training Data.

They are the ones having spatial resolution of 10m .. Using other bands may reduce the resolution..

I CANT BELIEVE THAT THIS IS WORKKKKKKKK, CAN I ASK YOU QUESTION WHY YOU USE ONLY 4 BANDS, MEANWHILE MAYBE THER IS SOME CLASSIFICATION THAT THE OTHER BAND

Hi! Can you share me with your codes

Why when i use "Sentinel-2: Cloud Probability" to mask the clouds, my overall accuracy went down from 0.7 to 0.578. 1) How to improve overall accuracy 2) How many Geometry Imports per class is need/best/sufficient

i try to do the same but i have this message ! (Jsloader error (code #1): Timeout reached for loading script /javascript/acorn.js) please can some one help me to fix this ?

Very good video. Congratulations! Just one doubt, I can't get the confusion matrix scrip to work, it doesn't give me any error, only that both the confusion matrix and the Overall Accuracy give me 0 value. What can it be?

hmmm, when i adjust scale to 10, the water classification output seems a bit off, using 30 then. Using the scale of 30, also improved the overall accuracy from 0.7 to 0.75

Please can you help me, I followed all steps and worked. But Finally it shows ''Classification_CART: Layer error: Property 'class' of feature '1_1_1_1_1_0_0' is missing''. How can I fix this problem . I am binger

@batconservationpakistan4645

He is only using blue, green, red and NIR because of higher spatial resolution of these bands (10m). Using 20m bands is of no use.
