I'm new to openlayers and I've a map project created in qgis and served by
qgis_mapserv.fcgi on linux system. This should
affect the openlayer part though.
I would like to display the overlays as vector layers. The code below shows
what I have now with the vector layers
displayed as a WMS image layer.

var map = new OpenLayers.Map('map',
{
controls: [
new OpenLayers.Control.Navigation(),
new OpenLayers.Control.PanZoomBar(),
new OpenLayers.Control.ScaleLine(),
new OpenLayers.Control.MousePosition()
]
},
{
projection: new
OpenLayers.Projection("EPSG:27700"),
}
);
var wms = new OpenLayers.Layer.WMS(
"Base OS Map",
"http://localhost/cgi-bin/mapserver/qgis_mapserv.fcgi";,
{
map: '/var/www/cgi-bin/mapserver/web-test.qgs',
format: "png",
layers:['SN11', 'SN01']},
{ gutter:0,
projection: new
OpenLayers.Projection("EPSG:27700"),
maxExtent: new OpenLayers.Bounds(200000,
210000, 220000, 220000),
maxResolution: 2500,
minResolution: 1,opacity: 0.5,
units: 'm'
}
);
map.addLayer(wms);
var rivers = new OpenLayers.Layer.WMS( "Rivers",
"http://localhost/cgi-bin/mapserver/qgis_mapserv.fcgi";,
{ map: '/var/www/cgi-bin/mapserver/web-test.qgs',
format: "png",layers :
['NaturalFeature_Line_11','NaturalFeature_Line_01'],
transparent: true, },
{
projection: new OpenLayers.Projection("EPSG:27700"),
maxExtent: new OpenLayers.Bounds(200000, 210000,
220000, 220000),
units: 'm',
maxResolution: 2500,
minResolution: 1,opacity: 1.0,
visibility: false,
}
);
map.addLayer(rivers);
var wawo = new OpenLayers.Layer.WMS( "Water, woods etc.",
"http://localhost/cgi-bin/mapserver/qgis_mapserv.fcgi";,
{ map: '/var/www/cgi-bin/mapserver/web-test.qgs',
format: "png",layers
:['NaturalFeature_Area_11','NaturalFeature_Area_01'],
transparent: true},
{
projection: new OpenLayers.Projection("EPSG:27700"),
maxExtent: new OpenLayers.Bounds(200000, 210000,
220000, 220000),
units: 'm',
maxResolution: 2500,
minResolution: 1,
visibility: false,
opacity: 0.5
}
);
map.addLayer(wawo);
-----------SNIP
I would like the "Water, woods etc." and "Rivers" to be vector layers. I assume
this is possible? Can anyone advice me how
I can do this? Reading the openlayers docs is un-enlightening and I can't find
any examples anywhere. Much time guessing
the settings has got me nowhere, except to here obviously.
Regards
Mike E
