Hi List,

I have two Raster images:

a) Landscan Image
b) Nighttime image

Where I resampled nighttime image using resample function in R,  taking
landscan image as a reference image. Now, I need to find out the measure of
alignment between these two images.

Apart from visual interpretation, I need to see the alignment in some
quantitative aspect (it could be RMSE etc.) so that I can check the measure
of alignment between the two rasters, raster - vector, vector - vector.

Please help me out with this.


Thanks very much in advance.

Priyanka
