MgGeometry Spatial Operator Test Cases
Geometry

These tests target the MgGeometry methods: Contains,Crosses, Disjoint, Equals, Intersects, Overlaps, Touches, and Within. The CoveredBy, EnvelopeIntersects, and Inside predicates are simulated using other MgGeometry methods. See the PHP code sections of CoveredBy, EnvelopeIntersects , and Inside . All of the tests should return true.

For those cases using the predicates CoveredBy, EnvelopeIntersects, and Inside, convert the AGF text specifications to objects of type MgGeometry and call the appropriate function passing the geometries in as arguments. 

$wktReaderWriter = new MgWktReaderWriter();
$geom1 = $wktReaderWriter->Read("POINT(1 1)");
$geom2 = $wktReaderWriter->Read("POINT(1 1)");
$boolResult = EnvelopeIntersects($geom1, $geom2);

For the other cases, convert the AGF text specifications to objects of type MgGeometry and call the appropriate method with the second MgGeometry object as the argument.

$boolResult = $geom1->Contains($geom2);
