I cannot get the projection to work, and I suspect it's the parameters for the UTM projection object. I am trying to project from UTM Zone 19N, NAD 1983 to lat-long. Here is my code: $projInObj = ms_newprojectionobj("proj=utm,ellps-GRS80,datum=NAD83,zone=19,units=m,north,no_defs"); $projOutObj = ms_newprojectionobj("proj=latlong"); $poPoint = ms_newpointobj(); $poPoint->setXY($xmin, $ymin); echo "<p/>Coords: " . $poPoint->x . ",".$poPoint->y; $poPoint = $poPoint->project($projInObj, $projOutObj); echo "<p/>x = " . $poPoint->x; echo "<p/>y = " . $poPoint->y; $poPoint->free(); I can see the output using the echo lines. The coordinates going into the point show up and are correct, but there are no x/y values after doing the project. Can anyone see what I'm doing wrong? ________________________________ _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users -- Pietro Giannini Bytewise srl - Area GIS 41°50'38.58"N 12°29'13.39"E
