The relationship is an inverse one. For example, if you have a 1 m error in a 30 m pixel, the percentage of error is much smaller than if you have a 1 m error in a 15 m pixel.

  • yes in case of meters but we calculate errors in pixel size on raw data then i think high resolution data is better rectified make me correct if i am wrong – Ayesha Oct 23 '14 at 21:02
  • I'm sorry, not really clear on what you're asking here. Are you concerned with which image you should rectify or which image will rectify most accurately? If the latter, my original answer still holds. – Chris Strother Oct 24 '14 at 13:31
  • i am concerned with unrectified image means the image on which i want to apply rectification. and i am considering value of RMSE in Pixel unit of unrectified image. – Ayesha Oct 24 '14 at 14:39
