Hi, This issue is related to:
* https://github.com/mapserver/mapserver/commit/722716c49de2399f54b275ab31437f0e8c92cd63 * https://github.com/mapserver/mapserver/commit/4c2aeb4bbd229723d8ea67c337cf02350575b2ae The issue is that when I try to visualize (via WMS) a layer with a NetCDF data file with longitude from 0° to 360° in EPSG:3857, there is a sliver around longitude 0° where no data is displayed. We already had that issue with the same files using EPSG:4326 and it's been fixed in MapServer (see merge request above). Here is where you can find example files: https://dd.weather.gc.ca/model_giops/netcdf/lat_lon/2d/00/003/CMC_giops_votemper_depth_0.5_latlon0.2x0.2_3h-mean_{yyyymmdd}00_P003.nc We are testing using: MapServer version 7.4.4 OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=SVG_SYMBOLS SUPPORTS=RSVG SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS SUPPORTS=POINT_Z_M INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE Here is a minimal mapfile to reproduce: MAP NAME "" IMAGETYPE PNG EXTENT -180 -90 180 90 MAXSIZE 4096 SIZE 500 300 IMAGECOLOR 255 255 255 PROJECTION "init=epsg:4326" END TRANSPARENT ON DEBUG 5 WEB METADATA "ows_extent" "-180 -90 180 90" "wms_getmap_formatlist" "image/png,image/jpeg" "wms_timeformat" "YYYY-MM-DDTHH:MM:SSZ" "wms_getfeatureinfo_formatlist" "text/plain" "ows_enable_request" "*" "ows_abstract" "" "ows_srs" "EPSG:4326 EPSG:3857" "ows_title" "" END END LAYER NAME "TEST" DEBUG 5 TYPE RASTER PROCESSING "GDAL_NETCDF_BOTTOMUP=YES" TOLERANCE 15 TEMPLATE "ttt.html" PROJECTION "proj=longlat" "a=6371229" "b=6371229" "lon_wrap=180" "no_defs" END DATA '' METADATA "ows_title" "" "ows_abstract" "" "ows_extent" "-180 -80.1 180 89.9" "ows_geomtype" "Geometry" END CLASS NAME "" STYLE COLORRANGE 0 0 127 127 0 0 DATARANGE 200.00 400 END END END END
