Surveys consist of a compass to determine the property’s orientation on your map. Depending upon the type of survey, you’ll see magnetic north (factors to the Earth’s magnetic pole or maybe the course by which a real compass will level) or geographic north (points on the Earth’s geographic North Pole). https://b.cari.com.my/home.php?mod=space&uid=2506516&do=blog&quickforward=1&id=526419
