First-Order Triangulation Point Kunimidake
On the way back from FOSS4G 2023 Japan @ FUKUI. While on a field trip using a rental car, I went to see the first-order triangulation point at Kunimidake.
The reason I am drawn to triangulation points is that they serve as the foundation for creating maps of Japan. You decide on a location, set a stone, and survey that spot accurately. Then, using this as a center, you determine the locations of various other points; the triangulation network is the framework for all of that. It is incredibly important.
Among them, first-order triangulation points are extremely valuable.
I don't go hiking or anything like that, so I don't often come across triangulation points like the ones found near famous mountain peaks (and since first-order triangulation points are often selected near the summits of such high mountains to ensure long-distance visibility, that is usually the case), but there are some first-order triangulation points that can be reached without much walking. My keyword is 'don't walk for more than 5 minutes after parking the car (or leaving the station)'.
This Kunimidake triangulation point is one of those first-order triangulation points that even a weakling like me can reach.
I parked the car in a parking bay on the shoulder of the road and climbed up this gentle path.
There was a fork in the road along the way, but recently I've finally started to be able to guess the location by getting into the mindset of the person who selected the site, thinking, 'I feel like they would want to set it here' (though I do miss sometimes).
The atmosphere is a bit unsettling, but there is still something that can be recognized as a path that people can walk on. Based on the elevation difference, it's definitely this way.
This feeling of 'Found it!!!' is irreplaceable.
This one is from the Ministry of Construction era. It is in very good condition, not chipped or buried.
You see, the 'First-Order' written from right to left, and the 'point' character that looks like meat—that's what's so good about it.
The positional relationship up to this point and the route taken this time.
