I meant what so the calls to MapServer from OpenLayers look like? Are you using WFS, custom MapServer queries or perhaps OGR output formats? Doesn't look like the latter from your mapfile.

Many thanks for investigating; please check below the relevant parts of the mapfile, as well as the openlayers related code; (the purpose is to display nooa gfs winds forecasts, "vents" means "winds" in french); some stuff like the SYMBOL part and the layer's STYLE part should not be necessary anymore with gml output, as well as few other directives, clean up job ahead..., but working, minus the maxscale (denom) directive which is not working in this configuration; I could manage the scale display control on the openlayers 3 side with an if case based on the zoom level, but I would prefer mapserver mapfile to drive it; Thanks again Blaise - - - - - - - - - - --- mapfile --- (called rg_noaa_vents_gml.map, called on the ol3 side) MAP NAME rg_noaa STATUS ON SIZE 600 600 EXTENT -180 -90 180 90 FONTSET "fonts/fonts.list" UNITS DD SHAPEPATH "data" IMAGECOLOR 230 230 255 TEMPLATEPATTERN "rg_noaa" IMAGETYPE PNG24 OUTPUTFORMAT # image mapfile # #TRANSPARENT ON #IMAGEMODE RGB #DRIVER GD/PNG # gml mapfile # NAME "gml" DRIVER "TEMPLATE" FORMATOPTION "FILE=rg_noaa_vent_gml.map" END PROJECTION "init=epsg:4326" END WEB HEADER templates/header_ol.html TEMPLATE "set in index.html" FOOTER templates/footer.html MAXSCALE 200000000 IMAGEPATH "/tmp/ms_tmp/" IMAGEURL "/ms_tmp/" METADATA "WMS_TITLE" "vrrroum_noaa" "WMS_ONLINERESOURCE" "http://localhost/cgi-bin/mapserv?map=/var/www/html/rg/blabla_02/noaa/rg_noaa_vents_gml.map" "WMS_SRS" "EPSG:4326" "WMS_ENABLE_REQUEST" "*" #"WMS_FEATURE_INFO_MIME_TYPE" "text/html" "wms_feature_info_mime_type" "text/gml" "WFS_ONLINERESOURCE" "http://ip-adress/cgi-bin/mapserv?map=/var/www/rg/blabla_02/noaa/rg_noaa_vents_gml.map&" "WFS_ENABLE_REQUEST" "*" "wfs_feature_info_mime_type" "text/gml" END END SYMBOL NAME "arrowfilled" TYPE vector FILLED true #FILLED false POINTS 1 0 -1 0 -1 7 -3 7 0 10 3 7 1 7 1 0 -1 0 END # POINTS END # SYMBOL LAYER ##### ##### ##### fv_168 NAME fv_168 GROUP v_168 TYPE POINT STATUS ON DATA fv_168 MAXSCALEDENOM 20000000 SIZEUNITS kilometers METADATA "WMS_TITLE" "v_168" "WMS_SRS" "epsg:4326" "wms_include_items" "all" "gml_include_items" "all" "WMS_ENABLE_REQUEST" "*" "wfs_title" "v_168" "wfs:srs" "EPSG:4326" "gml_include_items" "all" "gml_featureid" "ID" "wfs_enable_request" "*" END CLASS TEMPLATE "templates/vents.html" STYLE OPACITY 50 SYMBOL "arrowfilled" SIZE [VITREP] ANGLE [ANGLE] WIDTH 2 COLOR 100 100 150 END END DUMP TRUE HEADER "templates/vents_header_ol.html" FOOTER "templates/vents_footer_ol.html" TOLERANCE 20 END END # Map File - - - - - - - - - - - - - - --- openlayers 3 --- (extracts of the layer description) var gmlSourceV_168 = new ol.source.ServerVector({ layer: 'v_168gml', format: new ol.format.WFS({ featureNS: "http://mapserver.gis.umn.edu/mapserver", featureType: 'fv_168' }), projection: 'EPSG:4326', loader: function(extent, resolution, projection) { $.ajax({ url: 'http://ip-adress/cgi-bin/mapserv?map=/var/www/html/rg/blabla_02/noaa/rg_noaa_vents_gml.map&service=WFS&' + 'version=1.1.0&request=GetFeature&typename=fv_168&outputFormat=text/xml; subtype=gml/3.1.1&' + '&srsname=EPSG:4326&bbox=' + extent.join(',') }).done( function(response) { gmlSourceV_168.addFeatures(gmlSourceV_168.readFeatures(response)); }); }, strategy: ol.loadingstrategy.bbox }); var gmlLayerV_168 = new ol.layer.Vector({ title: '168gml', type: 'base', visible: false, source: gmlSourceV_168, style: (function() { function ruleStyle(vitrep, angle, lon, lat) { var ruleStyle = [new ol.style.Style({ image: new ol.style.Icon({ src: 'images/windarrow_42.png', rotation: angle * 3.141592654 / 180 }), })]; return ruleStyle; } return function(feature, resolution) { var vitrep = feature.get('VITREP'); var angle = - feature.get('ANGLE'); var lon = feature.getX; var lat = feature.Y; return ruleStyle(vitrep, angle, lon, lat); }; })() }); On 12/01/2014 08:50 PM, Lime, Steve D (MNIT) wrote: > How are you triggering the GML production in MapServer?
