Hi, I am completely stuck. Here is what I have... I have tried OL
2.10-RC1, and am now trying with OL 2.10-RC2. I am unsuccessful in
getting WMS and Gmaps v3 to draw together, but I have discovered the
following. Given
function init() {
var lon = -90.397;
var lat = 45.93;
var zoom = 8;
var map = new OpenLayers.Map('map');
map.addControl(new OpenLayers.Control.LayerSwitcher());
var counties = new OpenLayers.Layer.WMS(
"Counties",
"http://testmap.carbonmodel.org/cgi-bin/cnnf";,
{
layers: "counties",
map_imagetype: "agga",
transparent: false,
singleTile: true,
isBaseLayer: false
}
);
// Google.v3 uses EPSG:900913 as projection, so we have to
// transform our coordinates
var gphy = new OpenLayers.Layer.Google(
"Google Physical",
{type: google.maps.MapTypeId.TERRAIN}
);
map.addLayers([counties, gphy]);
map.setCenter(
new OpenLayers.LonLat(lon, lat).transform(
new OpenLayers.Projection("EPSG:4326"),
map.getProjectionObject()
),
zoom
);
}
If I have "transparent: false", my WMS layer draws, but Gmaps doesn't
draw. In fact, both my layer and Gmaps act like baselayers (they both
appear as radio buttons in the layer switcher). If I click Google
layer, my layer vanishes and the entire map shifts to 0,0 as the
center.
If I make my layer "transparent: true", my layer doesn't draw anymore,
but Gmaps does. Gmaps appears as a baselayer (radio button), and my
layer appears as a checkbox. Nevertheless, it doesn't draw at all.
If I change new OpenLayers.Projection("EPSG:4326") to new
OpenLayers.Projection("EPSG:3857") or new
OpenLayers.Projection("EPSG:900913"), I can actually see my layer
draw, on top of Gmaps, but only when I zoom way out.
Needless to say, I have EPSG:3857 definition added to our list of
valid projections.
What is the simplest possible syntax for drawing Gmaps v3 layer along
with a WMS layer coming from MapServer? What am I doing wrong above?
Thanks,
