Hi,<br><br>I have been doing more tests to try to identify exactly the problem and I ahve realized that, according to <a href="http://twcc.free.fr/" target="_blank">http://twcc.free.fr/</a>,
the coordinates returned when working with php_mapscript from version
4.10 are not correct. I am trying to get where is the problem, so that I
can decide wether sorting out a The issue is that the function project
returns different things depending on the server configuration:<br>
<br>Input coordinates in Google Spherical Mercator:<br>(-20500513.477395,-3641436.<div id=":1rf">715144)<br><br>Server 1: proj 4.1.5 and MapServer 4.10 returns (-90270074.105905,-216622133.8792)<br>Server 2: proj 4.1.7 and MapServer 5.6 returns (-20500513.477395,-3641436.715144)<br>
The World Coordinate Converter automatically transform the output CRS to
UTM 60S, so I can't not validate the transformation with it.<br> <br>The
issue is that I would like to understand the expected behaviour from
this function, so that I can go on checking it and defining the best way
to support the functionality or detecting a problem in servers
configuration.<br>
<br>The code is as follows:<br><br>function project($x, $y, $srsIn, $srsOut)<br> {<br> $pointObj=ms_newPointObj();<br><br> $pointObj->setXY($x,$y);<br><br> $pointObj->project(ms_newProjectionObj("init=".strtolower($srsIn)), ms_newProjectionObj("init=".strtolower($srsOut)));<br>
<br> $xout=$pointObj->x;<br> $yout=$pointObj->y;<br><br> $pointObj->free();<br><br> return $xout.",".$yout;<br> }<br>?></div><br><br>

<p class="MsoNormal">Dear list,<br>
<br>
I have a webgis application working with different CRS all over the world. I have realized that the behaviour from version 4.10 of the function pointObj->project differs from the one of version 5.6 from Mapserver. For example, I try to convert (-116,-15) in
4326 and in mapscript from version 4.10 it returns (-26158630.407638,-25040425.679281) when passing to 32630. On the other hand, in version 5.6 of mapscript it returns the original coordinates without transforming them.
<br>
<br>
Is this intended or am I doing something wrong? Which is the intended behaviour of project function in MapServer 5.6?<br clear="all">
