Description
I need project a shape and calculate the area, but, the result is not correct:
<?php
$wkt = "POLYGON ((-48.5190906467759575 -10.3694247662893702, -44.7171016213105545 -6.4122525152947691, -43.5532274298415558 -12.3092150854043680, -48.5190906467759575 -10.3694247662893702))";
$projInObj = ms_newprojectionobj("proj=latlong,ellps=GRS67");
$projOutObj = ms_newprojectionobj("proj=laea,ellps=GRS67,lat_0=-12,lon_0=-52,x_0=500000,y_0=10000000,units=m"); $geo = ms_shapeObjFromWkt($wkt);
echo "<br> Area before projection: ".$geo->getarea();
result 13.5129188146 ok
$geo->project($projInObj,$projOutObj);
echo "<br>Area after projection: ".$geo->getarea();
result 13.5129188146 !!!!!!!
