Hi, WCS 2.x supports GeoTIFF compression with parameter GEOTIFF:COMPRESSION:compression. It may not be so well documented in our own documents but you can have a look at the standard (I think it is in OGC® GML Application Schema - Coverages - GeoTIFF Coverage Encoding Profile). Mapserver documentation lists the alternatives as well https://mapserver.gis.umn.edu/ogc/wcs_server.html
For the customized tags you should probably have a WPS process. -Jukka Rahkonen- -----Alkuperäinen viesti----- Lähettäjä: Scott Lewis <scott.le...@colorado.edu> Lähetetty: keskiviikko 9. maaliskuuta 2022 22.11 Vastaanottaja: Geoserver-users@lists.sourceforge.net Aihe: [Geoserver-users] Preserving tags and compression Hi, I am relatively new to Geoserver stuff, and I have been working on configuring some data for my organization to be served by Geoserver. I have been able to get most of it up and running, but am running into two minor issues that I have not been able to find how to correct. I am using ImageMosaic to have a series of files for a particular layer, with a separate image for each day. I can query for individual days using WMS and WCS, and get expected results, but the two issues I have are with the output files themselves: 1) Is there a way to have the timestamp of the image included as a tag in the output GeoTIFF? We have tried a custom tag, as well as using "TIFFTAG_DATETIME", but in both cases, the file that is returned by GeoServer omits the tag, and does not include any kind of timestamp in the file. I would like to have this, because I have the layer set to use "nearest available" if a query is made for a time that doesn't exist, and it would be helpful for the user to know exactly which image is returned in that case. 2) Our source image files use LZH compression format, which is great as it makes the file much smaller. However, the file that gets returned by Geoserver does not have any compression. I have been unable to find a way to tell Geoserver to use compression when serving GeoTiff files. I appreciate any help in advance. I'm hoping both of these things are minor issues that my searching has just failed to help me find.
