I know that itīs possible to reproject from 4326 to 900913 with mapproxy. But as mentioned the user can add every WMS-Server heīd like to see in the application (that means he doesnīt choose from a limited list but can enter whatever he wants). So we cannot take the static approach and add them to the yaml-File manually. We would need some kind of script/interface which adds the given WMS-Server (with the requested layer maybe) to mapproxy temporarily.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Best regards<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Max Stephan<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> atrawog@gmail.com [mailto:atrawog@gmail.com] <b>On Behalf Of </b>Andreas Trawoeger<br><b>Sent:</b> 19 January 2011 15:50<br><b>To:</b> Max Stephan<br><b>Cc:</b> Oliver Tonnhofer; mapproxy@lists.osgeo.org<br><b>Subject:</b> Re: [MapProxy] Reprojecting google maps<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>2011/1/19 Max Stephan <<a href="mailto:max.stephan@gmx.net">max.stephan@gmx.net</a>><o:p></o:p></p><p class=MsoNormal>We donīt have an agreement with google concerning this. The reason why we want to reproject the google-maps-Data is that we are overlaying it with several WMS-Layers in our Open-Layers-based application. No problem so far but the users are able to add their own WMS-Servers and some of them donīt support EPSG:900913 but I guess each of them supports EPSG:4326.<br>So our second approach is to reproject data from those servers to EPSG:900913 but the problem is that this is not really working client-side (there is one approach using gdal-warp.js but itīs really slow and causes browser-crashes). Would it be possible to add those WMS-Servers to mapproxy temporarily to reproject them there?
