I have resized my original tiff file (1.5gb) to a tiff file (170mb). But there was no geo reference points in the resized image which was present in my original tiff file. I have attached the screenshot which shows the geoinfo(co-ordinate points) of my original tiff file.

georeferencing_tags_of_original_image

I need the geo reference points\co-ordinate points to this resized image from my original tiif file. How do i add it?

I have coded my image resizing in "Matlab". My code is as follows -

t = Tiff('D:\sample\a_01.tif','r'); 
imageData = read(t); 
Itrain = imresize(imageData,0.3); 
channel4 = Itrain(:,:,4); 
Itrain = Itrain(:,:, 1:3); 
scaled_train = mat2gray(Itrain); 
imwrite(scaled_train,'D:\com_1.tif')

Please do help me out!!

  • Please take a look at geotiffwrite: ch.mathworks.com/help/map/ref/geotiffwrite.html . – Leander Moesinger Dec 21 '17 at 11:05
  • @LeanderMoesinger I appreciate your suggestion. But that did not help me. Because to include [A,R] values, "geotiffread" isn't reading my tiff file. And if i don't have [A,R] values i can't proceed with "geotiffwrite" function. So i wish if u could help me with alternate for geotiffread or any other suggestion is always welcomed. – M. V.
