Also if I were to go upstairs I could maybe find one in the Pentlands. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16275#post-217041 Mon, 18 Apr 2016 19:56:07 +0000 wee folding bike 217041@http://citycyclingedinburgh.info/bbpress/ <p><a href="https://en.wikipedia.org/wiki/Retriangulation_of_Great_Britain" rel="nofollow">https://en.wikipedia.org/wiki/Retriangulation_of_Great_Britain</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16275#post-217022 Mon, 18 Apr 2016 15:22:33 +0000 cb 217022@http://citycyclingedinburgh.info/bbpress/ <p>...as long as he provides some distances or angles.</p> <p>I think there are seven trig points I can see from my house (assuming powerful telescope eyes). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16275#post-217021 Mon, 18 Apr 2016 15:18:13 +0000 Stickman 217021@http://citycyclingedinburgh.info/bbpress/ <p>One more reference point and we should be able to locate crowriver.... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16275#post-217019 Mon, 18 Apr 2016 14:55:35 +0000 crowriver 217019@http://citycyclingedinburgh.info/bbpress/ <p>I can see the Arthur's Seat trig point from my window as I type this. If I stand at the window I can see Calton Hill, but the trig point is obscured by tree tops. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16275#post-217018 Mon, 18 Apr 2016 14:44:12 +0000 cb 217018@http://citycyclingedinburgh.info/bbpress/ <p>I wonder if there was any opposition? I doubt it, but I'm about to start reading Map of a Nation so perhaps that will shed some insight.</p> <p>I've just 'discovered' that the three trig points closest to my house are almost equidistant from my front door with only about 120m between the distance to the closest compared to the distance to the furthest.</p> <p>How exciting is that? Very is the obvious answer.</p> <p>Then TPs 4, 5 and 6 (which are about four times further away) only have about 250m between the distances. That's doubly exciting.</p> <p>I'll save 7 and upwards until the weekend. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16275#post-217014 Mon, 18 Apr 2016 14:31:10 +0000 ih 217014@http://citycyclingedinburgh.info/bbpress/ <p>I love trig points and always tap them thankfully and affectionately. It is interesting to conjecture though, were it proposed today to erect some brutalist concrete pillars in prominent positions in some of the world's most beautiful scenery; would it be accepted? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16275#post-217008 Mon, 18 Apr 2016 13:33:20 +0000 chdot 217008@http://citycyclingedinburgh.info/bbpress/ <p>Technology before 'technology'.</p> <p>"</p> <p>Ordnance Survey (OS) is celebrating the 80th anniversary of the triangulation pillar, most often known as a "trig pillar" or "trig point" and a welcome sight to many a walker as they reach the peak of their walk.</p> <p>"</p> <p><a href="http://www.bbc.co.uk/news/in-pictures-36036561" rel="nofollow">http://www.bbc.co.uk/news/in-pictures-36036561</a> </p>
