Re: [mapguide-users] How do I set the right projection in OL for OSM?
Ok, I don't know exactly why but if I set EPSG 31467 for every feature source I have my Map goes visible and it's in the right location. -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users

Could you tell me how I can do this? I'm not familiar with fusion.

Re: [mapguide-users] How do I set the right projection in OL for OSM?
Can you look at your EPSG 3857 projected map definition in Fusion with external base layers on? Does the problem happen there too? - Jackie -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users

Do you mean the initial map view?

Re: [mapguide-users] How do I set the right projection in OL for OSM?
If you changed the map projection in Maestro, did the bounding box coordinates of the Map Definition change as well? If not, you're probably looking at the 3857 map but looking at it from the starting point of the un-projected 31467 bounding box view. In this case, you'll have to update the bounding box of the Map Definition with the projected coordinates as well. - Jackie -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] How do I set the right projection in OL for OSM?
Thanks for your help. I did set my map projection to EPSG 3857, now I can see the right location in OSM in Kaliopa Movile Viewer but I can't see my Map now (it's also not visible if I use the Preview in Maestro). If I set the projection back to EPSG 31467 my map goes visible. What I'm missing here? -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] How do I set the right projection in OL for OSM?
OpenLayers 2 doesn't do raster reprojection. You stating the displayProjection to be EPSG:3857 does not mean the MapGuide-rendered map image will be reprojected to it. What you should be doing is modifying that Map Definition so that its coordinate system is WGS84.PseudoMercator (which is EPSG:3857) and let MapGuide do all the reprojecting server-side when rendering the image. The displayProjection is then merely a declaration in OpenLayers that the map image that comes back from MapGuide is indeed in EPSG:3857 and everything should nicely line up. - Jackie -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
[mapguide-users] How do I set the right projection in OL for OSM?
Hello, I'm using the Kaliopa Mobile Viewer to display my MapGuide map and it works great so far but now I would like to add Open Street Map as BaseLayer but my map is always placed somewhere in the black sea. I know I have to set the right projection in Openlayers but how? In Maestro I can see the following information about the Coordinate System of my Map. PROJCS["DHDN.Gauss3d-3",GEOGCS["DHDN.LL",DATUM["DHDN",SPHEROID["BESSEL",6377397.155,299.15281535],TOWGS84[582.,105.,414.,-1.04,-0.35,3.08,8.3000]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["false_easting",350.000],PARAMETER["false_northing",0.000],PARAMETER["scale_factor",1.],PARAMETER["central_meridian",9.00],PARAMETER["latitude_of_origin",0.00],UNIT["Meter",1.00]] If I understand this correctly, then I get EPSG:4326, because I see "TOWGS84" in that string, right? But OSM works with EPSG: 3857. So I tried the following openlayers map Option: projection: "EPSG:4326", displayProjection: "EPSG:3857" But this does not do anything, my map is still in the black sea. Could someone give me a hint? I'm working with OpenLayers 2 and MapGuide Server 2.5.2 -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
