Hello my friends!
I have a problem with georreferenced tiff files. I need to get pixel
information from a geotiff image. I have the coordinates LAT LONG of a
ROI. Inside the Region of interest I need to get information about the
pixels, such as the many of pixels, and their values.
It seems to be very simple, but I can't find the right function. I've
tried to use CONTOUR, but it doesn't give pixel values. I've also
tried POLYFILL, but it just draws the polygons.
Could somebody please advise me with a function in IDL, so I could
work on?

Thank you very much

Aleksander
