Re: [UMN_MAPSERVER-USERS] Mapscript Re-Projection on-the-fly

[Delfos, Jacob]

Stefan,   Your question is not entirely clear. You can not re-project an individual layer on-the-fly, because php_mapscript does not re-write the dataset (hence its projection will always be the same); you CAN however change the projection of the map (using setProjection, as you did), which means all layers in the map get re-projected (the dataset remains unchanged, though). For this, it is required that your layer has a projection object with the native projection of that layer. This will cause the layer to be reprojected along with the map. Is this what you are trying to do?    You *may* have to save your mapfile, or your session, in order for it to take effect, depending on your setup.   regards,   Jacob   From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] On Behalf Of Stefan Schwarzer Sent: 24 August 2006 13:45 To: MAPSERVER-USERS@LISTS.UMN.EDU Subject: Re: [UMN_MAPSERVER-USERS] Mapscript Re-Projection on-the-fly Hey, I can't imagine that such a question stays unanswered in the mapserver community... I meanwhile added a: $map -> setProjection("init=epsg:26711"); to my code, but nothing happens - meaning: no error message but no reprojection either. Can anyone help me out? Thanks in advance.

Here and there (via MailingList and Google) bits and pieces, but altogether it didn't help me a lot. Though I would have said that this is a basic question. But perhaps too basic, so everbody finds out by himself? So, can anyone let me know - giving a coding example - how to re-project a mapfile on-the-fly from for example Lat/Long (global view) to Lambert or Robin?  Thanks a lot for your help!
