Thanks to Jeff for the answer.I simplified the mapfile to make it easier to read. Below I give the mapfile with these additional elements. I do not have warnings anymore with a GetCapabilities request but the image I get whith a GetMap request is still incomplete. Note that I get an error (/msProcessProjection(): Projection library error. proj error "projection not named" for ""/) with a projection block in the layer section if I declare the real projection definition (/"+proj=longlat +a=6378160 +b=6356775 +no_defs "/). No error with /"+init=epsg:4326"/ which is closed to the real projection definition. As I have read somewhere that if not present the projection is read in the data file, I have removed it (the image I get is the same). MAP STATUS ON NAME "foo" CONFIG "MS_ERRORFILE" "stderr" IMAGETYPE "agg" MAXSIZE 8192 EXTENT -180 -90 180 90 PROJECTION "init=epsg:4326" END OUTPUTFORMAT NAME "agg" DRIVER "AGG/PNG" MIMETYPE "image/png8" IMAGEMODE "PC256" EXTENSION "png" END WEB METADATA "ows_enable_request" "*" "ows_sld_enabled" "true" "wms_feature_info_mime_type" "text/html" "ows_onlineresource" "http://127.0.0.1:8080/wms"; "wms_title" "WMS" "wms_srs" "epsg:4326" END END LAYER STATUS ON TYPE RASTER NAME "polar_orbiting_avhrr4" DATA "/tmp/polar_orbiting_avhrr4.tiff" OFFSITE 0 0 0 PROCESSING "RESAMPLE=NEAREST" METADATA "wms_title" "foo" END #PROJECTION # "init=epsg:4326" #END #PROJECTION # "+proj=longlat +a=6378160 +b=6356775 +no_defs" #END END END
Give a good read to the projection page for MapServer (http://www.mapserver.org/mapfile/projection.html), take note of the Example#1, how to define the PROJ.4 parameters (I believe your error is because you've included the "+" by mistake), and then add in your projection block to your layer. And never assume that MapServer can magically read your projection and then announce that to all of your WMS users: always define each layer's actual projection. You can also experiment with the "PROJECTION AUTO" use, as described on that page, but I honestly avoid that and set all accurate projection definitions for each layer.
If this was my situation, I'd test this first without WMS, just with the shp2img commandline tool, by modifying my output project (see the "Important Notes" at http://www.mapserver.org/mapfile/projection.html#important-notes) and making sure that this layer is reprojected correctly; once that works, and I'm satisfied with the map image, I'd start testing the WMS reprojection.
