Dear All,
I am a newbie of mapserver and other online mapping technologies. Recently, I
have been struggling to load a TinyOWS WFS Layer to an OpenLayers map. I set
up proxy.cgi, which works fine. I checked TinyOWS using command "tinyows
-check", which also seems to be working. The page
http://.../cgi-bin/tinyows.exe?service=wfs&request=getCapabilities&version=1.1.0&typename=tows:lrtstops
doesn't return any error either. I can also load a mapserver WMS layer into
the OpenLayers Map with no problem. However, no feature from the WFS layer
would show in the OpenLayers map. Since both the WMS and WFS layers are of the
same projection, which is EPSG:2227, I assume that the misspecification of
projection is not likely to be the caprice here. The following is the
JavaScript I used and the response returned. Could someone help me find out
what I did wrong? Many thanks in advance!
OpenLayers.ProxyHost = "/fcgi-bin/proxy.cgi?url=";
function init() {
map = new OpenLayers.Map('map', {
projection: new OpenLayers.Projection("EPSG:2227"),
units: "feet",
maxResolution: "auto",
maxExtent: new OpenLayers.Bounds(6103631,1911230,6186389,1976404),
controls: [
new OpenLayers.Control.PanZoom()
]
});
var wms= new OpenLayers.Layer.WMS(
"parcel",
"http://.../cgi-bin/mapserv.fcgi?MAP=.../Parcel.map";,
{layers: 'Parcel', format: 'image/jpeg'}
);
var wfs = new OpenLayers.Layer.Vector("Editable Features", {
strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy],
projection: new OpenLayers.Projection("EPSG:2227"),
protocol: new OpenLayers.Protocol.WFS({
version: "1.1.0",
srsName: "urn:ogc:def:crs:EPSG::2227",
url: "http://.../cgi-bin/tinyows.fcgi";,
featureNS : "http://roappdev1:8080/";,
featureType: "lrtstops",
geometryName: "the_geom",
outputFormat: "text/xml; subtype=gml/3.1.1",
schema:
"http://.../cgi-bin/tinyows.fcgi?service=wfs&request=DescribeFeatureType&version=1.1.0&typename=tows:lrtstops";
})
});
map.addLayers([wms, wfs]);
