Hello,
I have some public Web Apps that use WMS layers coming from our ArcGIS Enterprise server. Same server provives WMS to other application and is also used in ArcGIS Pro. The problem I have is that raster image (GeoTIFF, 16bit unregistered, LZW original) that is served through server is showing as pixelated and bad quality on Online maps. And only those maps as it renders fine in all other applications. The issue is same if I publish raster directly to Online.
What I would like to know is if there's some other raster format that would be better to give proper quality. As the current rasters have transparency, we can leave even that out and control transparency with Online settings instead if that results readable images.
Attached are examples. One is how it look on Online map, the other is how servers JavaScript preview renders it.
@konstakuorikoski I would switch to png if I was you for discrete data like this
