Hi Even,
thanks for your response.
I just tried it with WEBP, but I'm getting the following error message:
Warning 6: 'WEBP' is an unexpected value for COMPRESS creation option of type string-select.Warning 6: driver GTiff does not support creation option WEBP_LEVELERROR 1: Cannot create TIFF
Am I overlooking something in my process?
No, you're just hitting a fundamental limitation of JPEG compresson
Do you have any ideas on how I can get rid of the artifacts while
still keeping disk usage low?
Use lossy WEBP compression that fully supports transparency.

Hi all,
I would like to serve GeoTIFFs via GeoServer as WMS / WMTS.
Basically, this is not a problem, but the GeoTIFFs should use as little disk
space as possible while still being very performant when accessed via WMS.
In the past, I worked with LZW compression, but the required storage space
Hi Seth,
Thank you for looking at this.
There are no errors in the apache error.logs.
Here is a tile request to mapserver:
https://map52.saltwatercentral.com/cgi-bin/mapserv?map=%2Fmaps%2Fwms%2Fhycom_2d_1.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=ml
Hi Steve,
Anything in the MapServer logs? And what is the actual network request to
MapServer?
You do have a "visible: false" set in your OpenLayers code - I presume this
gets changed by a legend at some point.
