I have just discovered Geo::ShapeFile module that gives perl the means to access the geometry of Esri shapefiles. Although I have been successful in getting the x and y co-ords I have not been able to get the z (height) values from my shapefile.

Anyone else using this module and experience the same problem ??

Below is the code I wrote to get the x,y co-ords and z (height) values for a test shapefile. 
use Geo::ShapeFile::Point comp_includes_z=>0;
use Geo::ShapeFile;

#reads the "test3D" shapefile layer.
$shapefile = new Geo::ShapeFile("test3D");
#loops throught each shapefile and gets the shape
#for each record
for (1 ..$shapefile->shapes){
    $shape = $shapefile->get_shp_record($_);
    #puts the points into an array of hashes
    @point = $shape->points;
    #for each point get the x,y co-ords and the
#(hieght) values and print
    foreach $p (@point){
        $x=$p->X;
        $y=$p->Y;
        $z=$p->Z;
        print "$x, $y, $z \n";
    } 
}

Any help is greatly appricated.
