Koordinat acok dipiliah sadamikian rupo sainggo salah satu angka mawakili [[altitudo|posisi vertikal]], dan duo atau [[vektor-N|tigo angka]] lainnyo mawakili [[representasi posisi horizontal|posisi horizontal]]. Umumnyo koordinat nan dipakai adolah kombinasi antaro [[garih lintang|lintang]], [[garih bujua|bujua]], jo [[katinggian]].<ref name=OSGB>{{Citation |title=A guide to coordinate systems in Great Britain |date=Mar 2015 |series=D00659 v2.3 |accessdate=2015-06-22 |publisher=Ordnance Survey |url=http://www.ordnancesurvey.co.uk/docs/support/guide-coordinate-systems-great-britain.pdf }}</ref>
[[Garih lintang]] adolah garih tagak luruih (vertikal) nan mangukua suduik antaro suatu titik jo garih [[katulistiwa]]. Titik di utara garih katulistiwa dinamoan [[Lintang Utara]] sadangkan titik di selatan katulistiwa dinamoan [[Lintang Selatan]].
