I’m working with an imagemosaic store composed of geotiff multiband rasters all projected in EPSG:3857. The layer has a TIME dimension define in the index.properties file correctly and working fine. In the WMS request I use the vendor parameter CLIP which is clipping my png return image with a polygon define correctly in SRID4326 with the extended parameter : SRID=4326;Polygone((…etc.)) and it works fine. (Just a small rendering issue that you can see in join file “Clip_image.png” where we see that contours are pixelized. From my opinion this is due to a CLIP method apply at a too early stage before bicubic interpolation is applied.) The big issue is when you use both parameters in the same WMS request : TIME=YYYY-MM-DD/YYYY-MM-DD and CLIP=srid=4326;POLYGON((…)) it returns you the wrong image (at a wrong date) but correctly clipped. Actually this is strange because it returns always the image corresponding at the closest |
