Hello All,I have historic aerial photos in TIFF format:[ATTACH=CONFIG]24202[/ATTACH]These display just fine (in State Plane)The problem arises when I re-project them to UTM (NAD83) -> JP2 format (same with TIFF format too)There is a dark area (some what resembling the extent).[ATTACH=CONFIG]24203[/ATTACH]When I set the display nodata value of 0 to NoColor, I get a tolerable image but still has some speckles in the collar area and holes inside (obviously 0 is a value).[ATTACH=CONFIG]24204[/ATTACH]During the re-projection process: I tried various methods - resampling, setting NoData, compression , etc. Evrytime it is the same result (dark around).[ATTACH=CONFIG]24205[/ATTACH]Am I missing something?Is there a work-around?Thanks
Thanks for the responses.Yes, I tried it the black collar has the value 0. So display background set to Zero.[ATTACH=CONFIG]24208[/ATTACH]The problem some of the areas inside (valid) also have zero values. So holes are showing up while the collar is removed (minimized).[ATTACH=CONFIG]24209[/ATTACH]Seems to be the problem repeatedly for different datasets.
