I'm working with a tiff image in arcgis projected in UTM 33N and I need to obtain pixel coordinates of a specific point in the image with known metric coords (UTM 33N). How can I get them?
There would be two ways to get your coordinates.
The second way is to convers the raster into a point feature class. You can do it through your ArcToolbox -> Conversion Tools -> From Raster -> Raster to Point.
After ths click with identify on the point you want the location from.
I hope this will work for you.
