| Jan 30, 2019 at 14:16 | comment | added | Gabriel | @AndrewJennings Just a slight correction, most topo maps (which use UTM or MTM projections in North America) aren't exactly aligned on true north except for the ones that are roughly centered on the zone's projected central meridian. Magnetic declination should be calculated between magnetic north and the grid on your map if you're trying to follow map features. If you want to follow an orientation relative to true north, you need to correct further to true north. I make paper maps and include all that metadata so users can go as precise as they want and it's sometimes over 1° of shift. | |

More specific title ("question", "beginner" are not informative), fewer thanks

| Dec 6, 2018 at 16:53 | comment | added | Andrew Jay | @MartinF - Steve is asking if there is a way to orient a map with a compass but beeline without it. I assume he's not asking about using technology - like a GPS - but rather, to do it by eye. | |
| Dec 6, 2018 at 16:50 | comment | added | Andrew Jay | Just to clarify, maps are written according to true north, while compasses can only work according to magnetic north. So there is no magnetic north on a map. If there is a magnetic north designation on it, then the map will expire, since magnetic north changes over time. Also, there is no way to orient a map without a compass' baseplate and travel arrow (you might get away without the travel arrow if you know which way was magnetic north). Otherwise, you'd have a 50/50 chance of orienting the map without using a travel arrow - which is odd considering all compasses have one. | |
