Hi, You are using some custom CRS in Geoserver, EPSG:45557. Could you add the WKT that you have used for configuring it?

The problem with the systematic shift of layers in LCC projection persists. Steps taken to reproduce: 1. Rasterize the states layer (I used the VectorToRaster WPS). 2. Reproject to Lambert Conformal Conic: gdalwarp -ts 2145 1377 -t_srs '+proj=lcc +lat_0=25 +lon_0=-95 +lat_1=25 +lat_2=25 +x_0=0 +y_0=0 +R=6371000 +units=m +no_defs' states_4326.tif states_45557.tif 3. Configure the reprojected raster as a Geotiff store. 4. Make a getMap request: https://wfas.firenet.gov/geoserver/osm/wms?service=WMS&version=1.1.0&request=GetMap&layers=osm%3Astates_45557,osm:states&bbox=-2973344.8603333654%2C-4525.983623652253%2C2805742.5427372716%2C3061083.104743568&width=768&height=407&srs=EPSG%3A45557&styles=&format=application/openlayers<https://eur06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwfas.firenet.gov%2Fgeoserver%2Fosm%2Fwms%3Fservice%3DWMS%26version%3D1.1.0%26request%3DGetMap%26layers%3Dosm%253Astates_45557%2Cosm%3Astates%26bbox%3D-2973344.8603333654%252C-4525.983623652253%252C2805742.5427372716%252C3061083.104743568%26width%3D768%26height%3D407%26srs%3DEPSG%253A45557%26styles%3D%26format%3Dapplication%2Fopenlayers&data=05%7C01%7Cjukka.rahkonen%40maanmittauslaitos.fi%7C7f7ad617f40f4cc0971608db02bbc084%7Cc4f8a63255804a1c92371d5a571b71fa%7C0%7C1%7C638106777639503897%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=JK%2B38OSMDa9GgciJuyOmNkJyaE4lrtsfGrtQfGXc7fg%3D&reserved=0> Upon zoom/pan around the misalignment of the data is visible. 5. Import states_45557.tif as a layer in QGis, and add the WMS layer from Step 3. The misalignment is visible in the attached screenshot. I believe this problem occurs when making a WMS request. If the layers is exported wia WCS, it displays fine in QGis. What advice would you give me to rectify this issue?
