Image pixel conversion to Latitude and longitude of that position

Hi all

I am working on a project with matlab. I am trying to convert a image pixels into its corresponding latitude and longitude of that position to find that location on the google map. I have a 618x998 image that I ma using. details of its upper left corner or pixel(1,1) are as lat = 50.421442 and long = -104.592987. and its far corner (618,998) lat = 50.412676 and long = -104.584345. its pixel resolution is 1pixel = 1.0465 meters.

Is there any way i can covert a certain pixel let say 125,285 into its corresponding lat and long position with this available info. Please help me with this problem.

You need to change the XTick, YTick properties of the image.

Thanks for replying. Can you please little elaborate I'm not sure how to get that.

if true
load clown
im = image(X);
hAxes = get(im, 'Parent');
set(hAxes, 'XTick', [Tick1 Tick2 Tick3]);
set(hAxes, 'YTick', [Tick1 Tick2 Tick3]);
set(hAxes, 'XLim', [minLong maxLong]);
set(hAxes, 'YLim', [minLat maxLat]);
end

If you have MATLAB 2014b or 2015b, you can do: im.Parent.XTitck = [values]; etc.

Hope that helps.

Hi U have MatLab 2014b And I am using this command: A.XTitck = [-104.592987,-104.584345] A.YTitck = [50.421442 , 50.412676] this is running without a error but when I'm opening A instead of showing a matrix it gives me A = XTitck : [-104.592987,-104.584345] YTitck : [50.421442 , 50.412676]

Sorry about that. I corrected it now. A.Parent.XTick.

This just puts up axes tick marks - it doesn't "convert" anything. If you have a certain row and column, you'd need to use a typical scaling equation to turn the (row, column) coordinate into a (latitude, longitude) coordinate.
