but if wikipedia can be believed http://en.wikipedia.org/wiki/Four_Corners_Monument then the quadripoint depiction remained unchanged & unrenovated as recently

Great fun - I wish though that when writeups such as the Wikipedia one give Lat and Long they would say what reference datum they are using. Without that

thanx & good point tho in cases like these where the technical savvy of the source cant be taken for granted i think you just have to guess they mean nad83 on

The latitude of that particular point was presumably intended at the time to be dead on 37 degrees North, but when I zoom in as closely as possible on the

As I can see you cannot trust Google Earth 100% when it comes to positions and borders. 0 doesn t even hit Greenwich Observatory

I went to maximum magnification on Google Earth and found that it did indeed show zero longitude as being about three quarters of the way to the far side of

Take a look here where the difference between WGS84 and various other observations is documented at various locations along the prime meridian

Each entry made records the actual WGS84 coordinates displayed on a GPSr device that is positioned at a physical marker which is marking the Prime Meridian.

ok thanx i get it but i am also still trying to figure out if there is anything useful for trypointing in these conversations that is somehow still eluding me

If you recall the start of this thread (which has change titles a few times now) it was the Lat and Long information provided for the US state quadripoint

indeed it might be loveliest if these conversations inspired someone to recall to mind or more likely & even better yet to create for the first time ever such

I d like to comment on this. Even at the present state of the art, you cannot expect a hand held GPS to get you to an exact set of coordinates. It will get

I think we are in somewhat violent agreement. But, as I mentioned, some datums (e.g. Tokyo datum) can be up to 200m off from WGS84 which could put you too far
