<div>Hi Gery,</div><div><br></div>Ok so here the issue is like this,<div><br></div><div>As u can see the <a href="https://www.dropbox.com/s/31woicfkusbs4yv/Overlay.png">Map</a> is working fine when the overlay shapefile which is<b> not a basemap </b>(star) is overlaid onto OSM and GMaps. If you look at the footer the co-ordinates are all wrong. <b>How do I get that right?</b> Now the AllQuebecSpecies (star), in the <a href="https://www.dropbox.com/s/31woicfkusbs4yv/Overlay.png">Map</a> is originally EPSG:4326 which I was successfully able to reproject to EPSG:900913 and it is working great.</div>
<div><br></div><div>When I try to add a <a href="https://www.dropbox.com/s/qgpcp5q4sf9qhls/Raster.png">raster bio11</a>, which is basemap, it is originally EPSG:4326 and according to the <a href="http://docs.openlayers.org/library/spherical_mercator.html">document</a> Gery provided, it says that Geoserver has a inbuilt feature to handle the spherical Mercator and so we do not need to re-project it. <b>So I simply added the raster as a WMS along with OSM and GMaps, but as u can see in this <a href="https://www.dropbox.com/s/hmcke8kleyw42d4/Bad_Projection.png">OSM map image</a>, there is a lot of shift.</b> The <a href="https://www.dropbox.com/s/hmcke8kleyw42d4/Bad_Projection.png">OSM map image</a> was taken in the same position as the <a href="https://www.dropbox.com/s/qgpcp5q4sf9qhls/Raster.png">raster bio11</a>. Also the <a href="https://www.dropbox.com/s/qgpcp5q4sf9qhls/Raster.png">raster bio11</a> footer shows the right co-ordinates but when I switch to <a href="https://www.dropbox.com/s/hmcke8kleyw42d4/Bad_Projection.png">OSM map image</a>, the co-ordinates go bad. <b>Also when I add <a href="https://www.dropbox.com/s/qgpcp5q4sf9qhls/Raster.png">raster bio11</a> without the projection, the AllQuebecSpecies (star), which is not a basemap, also just not appear when I switch to GMaps or OSM.</b></div>
<div><br></div><div>I hope this explains better.</div><div><br></div><div>Thanks & Regards,</div><div>Smaran Harihar</div><div><br><br><div class="gmail_quote">On Thu, May 24, 2012 at 3:45 AM, Gery . <span dir="ltr"><<a href="mailto:gamejihou@hotmail.com" target="_blank">gamejihou@hotmail.com</a>></span> wrote:<br>

Hi Smaran,<br><br>That's nice, uhmmm I've had I think the same problem before, but not sure about the issue itself, could you post your code to see what is going wrong? also some images to illustrate your problem.<br>

<div><div class="h5"><br><br>Hi Gery,<div><br></div><div>Thanks for the reply, I was able to resolve some of the errors. Ok the openlayer docs said that Geoserver is compatible with EPSG:900913 so I removed any projections and it now overlays fine. But there is some shift between my WMS base layer and OSM and GMap.</div>
<div><br></div><div>Also the new problem that I am facing is that the lat and long that is displayed in the control is fine if I display my WMS, but if I change the basemap to OSM or GMap again the lat long goes haywire. Also the other WMS with property 'isBaseLayer': false is overlaid on my WMS basemap but not on OSM and GMaps. (Which was happening earlier).</div>
<div><br></div><div>Any suggesstions?</div><div><br></div><div>Thanks & Regards,</div><div>Smaran Harihar<br><br><div>On Wed, May 23, 2012 at 1:27 PM, Gery . <span dir="ltr"><<a href="mailto:gamejihou@hotmail.com" target="_blank">gamejihou@hotmail.com</a>></span> wrote:<br>

Hello,<br><br>I think this link may help you about 1 and 2: <a href="http://gis.stackexchange.com/questions/26030/sometimes-a-white-square-dialogue-appears-in-the-middle-of-the-screen-map-data" target="_blank">http://gis.stackexchange.com/questions/26030/sometimes-a-white-square-dialogue-appears-in-the-middle-of-the-screen-map-data</a><br>
<br>I think 3 is because of the projection, google maps only works with 900913, so you have to add a line, if I remember well, almost at the end of your <script> tag to do the conversion, or it is something about proj, not sure because Im writing from memory, take a look here anyway: <a href="http://docs.openlayers.org/library/spherical_mercator.html" target="_blank">http://docs.openlayers.org/library/spherical_mercator.html</a><br>

Subject: [OpenLayers-Users] Pink broken images<div><div><br><br><div>Hi,</div><div><br></div>I am trying to create a base map of OSM, Google Roadmap and Google Hybrid and mash it up with my own base layers in Geoserver. So these are the problems I am facing,<div>
<br></div><div>1. I have two WMS that I am mashing up, on which is BaseLayer and another one is 'isBaseLayer' : false. The one with base layer is appearing as pink tiles with broken image and the 'isBaseLayer': false is rending perfectly over OSM, GoogleMaps. Any reason y? I have changed the projections using the following code,</div>
<div><br></div><div><div>var geographic = new OpenLayers.Projection("EPSG:4326");</div><div><span style="white-space:pre-wrap"> </span>var mercator = new OpenLayers.Projection("EPSG:900913");</div>
<div><span style="white-space:pre-wrap"> </span>var world = new OpenLayers.Bounds(-180, -60, 180, 90).transform(geographic, mercator);</div><div><span style="white-space:pre-wrap"> </span>//var center = new OpenLayers.LonLat(-104.98, 39.76).transform(geographic, mercator);</div>
<div><span style="white-space:pre-wrap"> </span>var options = {</div><div><span style="white-space:pre-wrap"> </span>projection : mercator,</div><div><span style="white-space:pre-wrap"> </span>units : "m",</div>
<div><span style="white-space:pre-wrap"> </span>maxExtent : world</div><div><span style="white-space:pre-wrap"> </span>};</div><div><br></div><div><span style="white-space:pre-wrap"> </span>var map = new OpenLayers.Map("map-id", options);</div>
</div><div><br></div><div>2. Since I have added the Google Maps and I am using v3.2, there is this splash screen appears every time the map loads or if i pan it around. How can i remove that screen? I close it by clicking on the cross and then again pan or click on the map and there it is again.</div>
<div><br></div><div>3. When I had initially added my two baselayers, the map control which got the lat and lon was giving the right co-ordinates but when I added the OSM and GMaps, the co-ordinates are completely different. Why is that? Is it because of the spherical Mercator? How can I make it right?</div>
