Hi, I have been doing more tests to try to identify exactly the problem and I ahve realized that, according to http://twcc.free.fr/, 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:
Input coordinates in Google Spherical Mercator: (-20500513.477395,-3641436. 715144) Server 1: proj 4.1.5 and MapServer 4.10 returns (-90270074.105905,-216622133.8792) Server 2: proj 4.1.7 and MapServer 5.6 returns (-20500513.477395,-3641436.715144) The World Coordinate Converter automatically transform the output CRS to UTM 60S, so I can't not validate the transformation with it. 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. The code is as follows: function project($x, $y, $srsIn, $srsOut) { $pointObj=ms_newPointObj(); $pointObj->setXY($x,$y); $pointObj->project(ms_newProjectionObj("init=".strtolower($srsIn)), ms_newProjectionObj("init=".strtolower($srsOut))); $xout=$pointObj->x; $yout=$pointObj->y; $pointObj->free(); return $xout.",".$yout; } ?> 2012/4/16 Lime, Steve D (DNR) <steve.l...@state.mn.us> > The transformation is done in place, I’ve not had problems with it.
