Image Pixels Correction in Remote Sensing

[Music] - good evening in the last lecture we discuss about - the classification and in this part we will talk about if there are few pixels which are not belongs to which has given here like this yellow color is showing the problem but if this is not means these pixels are not crognard then how we can choose to you know the x-ray de lettres so for that very purpose the the the easy way is will take the teams here and go to conversion and from duster to point I will get this one then by by value I will convert this rusted to point it so these are the points which are opposite to different nine classes I will go to the property symbology the degree is based on the red coat like that and add on values yeah and you can see here the first one is water so you can give bloom this is vegetation the Baron is greater go down the sport and fifties okay lay okay as you can see one two three four five as you can see here suppose this fixins showing the agriculture wrongly so how we can change this patient X 1 let us what you will do here you will select these X's here step by by pressing this shift go to open attribute table and choose the selected option but to hear and the calculator yes this is trick or equal to if you have to convert it four to five five you can see here the color of these points the market has changed so similarly you can suppose this person this time this is vegetation in trail this is not the vegetation this is the other category then you can change Phil calculator yes to fight okay now you can see the point color is changed when you are satisfied with all the changes thereafter again these points you can change to the desktop remember your value field should be the great hood and sense I should be the same website which was 30-meter yes I will make a 30-meter then I will change let us again it has been changed now you can see by matching the color that is you okay second is vegetation here third is paramdham and fourth is codename and the last is others okay now you can see we are gonna look so this was the way how we can direct our raster data by converting from raster to point and again from point 2 plus there thank you for listening and watching in the next lecture we will discuss about the accuracy assessment thank you so much you
