Resolution loss

[Schornagel]

Hello all,

I am new to ArcGIS, and I'm having trouble with image resolution.
I have a geotif that I would like to load as a layer, but when I do it appears pixelated and grainy.
I've attached a screenshot of the original .tif (right) alongside the same .tif loaded into ArcMap (left) to illustrate my point.

Is there any way to retain the original image quality?

Any help with this would be greatly appreciated!



Thanks

Hi,

Please open the image properties in Arcmap and go to the Display tab. You will need to change the Resampling Method. It is probably on Nearest Neighbor, and you need to change it to Bilinear Interpolation.

Thanks Gayathri!

That didn't fix it altogether, but it definitely improved.

Did you determine if the issue is the pyramids or the source raster? Besides the resampling technique, perhaps recreating the pyramids for the raster with a different resampling technique will also improve the performance. The resampling method can be set in the environment settings.
