I found this really helpful thank you very much

[@geodev]

Glad to hear it!

Thanks for your valuable content. for test dataset like train dataset We need to normalize and make numpy array as well for testing of our deep learning model. Is it correct or not? just want to be sure. Because in this video you just make train data normalized and numpy.

thanks very much!

Thank you for this informative video. I have a query. Is there any way to generate a mask without a shape file?

[@geodev]

If you are planning to use geotile package, you can use any type of vector layers such as geojson, shp etc. But there are other simpler ways too. One thing is, you can use the threshold based on some indices such as NDWI, NDBI MNDWI and create the mask file. But definitely it will also be less accurate label.

@@geodev Thank you for the quick response. I am using QGIS software to create mask using semi supervised method. But, as you mentioned it is less accurate. Is it possible to get shape file of specific region for multiclass task?

please share the video to install geotile package

when we get data, in geotiff, for a marked area of our choice problem is its resolution are very small, I tried different way, but I want like 50 , 60 mb of file with high pixel values and greater quality

[@geodev]

You mean while downloading the dataset from GEE?

[@muhammadhammadbashir8989]

@@geodev I have trained a model on public datasets like land cover which is detecting the segmenting the greenery, now I want to do this thing for another city let say Pokhara, but when I download images from sentiental 2 as you mentioned images quality are too bad, so thats why I want high size image, and yes its from GEE

[@DangHunghunh]

thanks a slot, but i cannot install geotile packages :(

[@geodev]

Have you tried with conda? I suggest to run following commands; 1. conda install -c conda-forge geopandas 2. conda install -c conda-forge rasterio 3. conda install -c conda-forge geotile

@@geodev yes now iam done, thank u sir so much. iam logging 3 account to subcri your chanel :D

@@geodev I have one more question, can I apply this method to classify multiple objects?
