pixel size is 26.9 or 27m by 27m. Why you use 30 x 30m?

I have prepared this Raster using Landsat Image which has a spatial resolution of 30meters by 30 meters

in this video, the raster is a land cover classification from Landsat imagery, some Landsat's bands have a 30x30 meters resolution

sure the 900m²/pixel is constant over the area? 🤔

when converting to the right unit. you do 30*30. how do you know to do this?

What Im doing wrong, if the process is just taking too long? Im am talking about wating for hours before shutting down manually. I dont even have as much pixels as you and I decent computer, I just cant explain why this method takes so long in my case. Im trying it for days now and im getting pretty frustrated. Maybe you can help me with the problem. Im using a Geotiff as Layer with a pixel size of 10x10m

Hello thanks for this useful video, but i am not able to understand where has 30 come up for multiplication and why have you taken 30 two times? pls reply soon , thanking in anticipation.

Hello Parishram, 30 meters is the spatial resolution of the images. That's why we have taken 30*30

Hello. I wanna Understand well... I didn't see 30m in your raster file. but, 30*30 is a bit strange for me. Why you didn't use width and height in pixel? I want to Understand well. Thanks

​@@a.l.leroyyapi Pixel size ( as shown in the video ) = 0.00026945852358569057 degree, in each direction To convert it from degree to meter; Meter = Degree * 111319 ; 0.00026945852358569057 * 111319 = 29.995853387 ≈ 30 meter as he used in the video

the resolution of my data is 10m , so i will do it like 10*10 with pixel count to get area in sq mts. is that all? thanks

You can ignore its pixel counts
