Hi guys
I am displaying POIs (speed cameras) via WMS as overlay on top of a Google base
map. When I drag the map (in my case) to the left the POI markers disappear
from the map. When I drag the map back they reappear. It appears data is coming
back from GeoServer each time, but doesn't always make it on the map...
I am using
* OpenLayers 2.8
* GeoServer 2.0.1
* Firefox 3.6.3
Data is coming from Oracle, but the same happens if I attach an shapefile data
store. Native SRS of the layer is EPSG:2193 (EPSG:NZGD2000 / New Zealand
Transverse Mercator ), but it doesn't seem to make a difference whether I let
GeoServer serve them with EPSG:2193 (native) or reproject to EPSG:900913.
I also just realised that the phenomenon happens with all my WMS layers. I
suspect I am missing something very obvious, but are stuck nonetheless. Any
pointers much appreciated!
My OpenLayers code is:
var map;
function init(){
var options = {
projection: new
OpenLayers.Projection("EPSG:900913"),
displayProjection: new
OpenLayers.Projection("EPSG:4326"),
units: "m",
numZoomLevels: 20,
maxResolution: 156543.0339,
maxExtent: new
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34)
};
map = new OpenLayers.Map('map', options);
var gphys = new OpenLayers.Layer.Google(
"Google Physical",
{type: G_PHYSICAL_MAP,
'sphericalMercator': true, numZoomLevels: 20}
);
var wmslayer2 = new OpenLayers.Layer.WMS(
"Speed Cameras",
"http://localhost:8080/geoserver/wms";,
{'layers': 'SPEED_CAMERA',
'format':'image/png', 'transparent':'true'},
{'opacity': 1.0, 'isBaseLayer': false,
'visibility': false}
);
map.addLayers([gphys, wmslayer2]);
Cheers
Tobias
