Google Earth Engine Tutorial: Landsat 7 Gaps-Filling

[@space-time-somdeep]

Didn't clear.. how much we have to zoom in? And what if we increase the Karnel Size, from 1 to let's suppose 5?

[@artspcx]

permisi bang mau nanya, saya udah coba script yang tertera di video tersebut. terus saya praktekkan ke script landsat 7 SR dengan script supervised classidication (svm) itu kok gak bekerja ya untuk mengisi gapfillnya?

[@stephensodoke8980]

the line strip of lines are still on the image, any advise on what to do

[@kholismunawar2918]

Thanks, its useful. but how to do the cloud masking function and followed up by this filling gap? I did try but the cloud still exist

[@nilamila1]

The gap filling is not working in my case! What could be the problem? it's saying "L7coll.focal_mean is not a function"

[@INSGIS]

hmmm you should share your script, so i could look further

@@nilamila1 focal_mean need an image as a input, not image collection. So, you have to convert it before. If you see in my vid, I used first() function as a last filter to pick first image in collection and convert it to image type.

@@INSGIS @Md Tawhid Hossain You can apply a function like this: function corrScan (img){ var img_fill = img.focal_mean(1, 'square', 'pixels', 8); var img_corr = img_fill.blend(img); return img_corr; } and then apply the function like this: imgCol.map(corrScan ); Hope this is usefull for you!

Very useful

How to add l7 style

[@ernestg7466]

@@abilitymatutu883 The style is defined beforehand in order to display the images and you can customize it according to your needs. If you notice it appears in the import bar and is added to that section automatically. Here you have an example, you declare it as a variable. var Visual_Landsat2009 = {"opacity":1,"bands":["B4","B5","B3"],"min":0.021442476933903,"max":0.27750826620608177,"gamma":0.853};

[@ernestg7466]

but you can call it L7_style if you wish.

[@abilitymatutu883]

I am trying to say how to add bands min and max value

[@ernestg7466]

​@@abilitymatutu883 Precisely, look at the example of the Visual_Landsat2009 variable in "min" and "max" values allow you to add those desired values. If you notice the variable has several parameters that allow you to manipulate its characteristics, opacity, bands and their values and gamma.
