Distances / Loft Location / Latitude and Longitude

[Newbie2020]

I have been looking at my distances and comapring the co-ordinates from google earth to my print out of my distances. How is it possible to have a different lat/long???? I have put on my actual lat/long on google earth and its showing me to be 2 streets closer to the first race point than I am actually am???

 

How is this possible and does anyone elses come up like this??

 

Very confusing, but surely the two should tally???

we done this last week 6 of us having a few beers messing about on the net and not one of ours added up we took no notice and took it google earth was wrong mate. ??) ??) ??) ??) :-/

i think that the way our distances are measured need to be looked at again as i got most of mine in 1997 which is not that long ago. some of the guys that have been racing for alot more years than that must have got their distances way back. with new uptodate technology i am sure that the measurements would be made more accurately.

WE GET NEW DISTANCES ALMOST EVERY YEAR AS LIB SITES ALWAYS CHANGING

their has got to be a good few lib sites that have been used for years .as most of my distances have not changed .

yip we have  1 or 2  but are always going to different race points every year

[just ask me]

google earth states it can be out by 30 or 60 meters not sure which one

[Guest stb]

60 meters is 2 streets awy realistically

[just ask me]

60 meters is 2 streets awy realistically

 

 

or else very long streets  ;D ;D ;D

 

[Guest slugmonkey]

we carry a gps on our truck and we check at every release and put coordinates into the winspeed program which automatically computes distances

 

always use the same gps unit for loft surveys as diffrent units will sometimes give diffrent results

60 meters could cost you an open or national 4 yards could :-/ :-/

.1 OF A YARD HAS BEFORE ..   THE PINPOINT FOR MAP ON AN ORDINACE SURVEY MAP WHICH IS USED TO PINPOINT LOFTS IS APPROX 30FT EITHER WAY,,  U WIN SOME U LOOSE SOME

[REDCHEQHEN]

Google Earth is 120 yards different from the co-ordinates I've got

and so is GPS (the guy who did them said it was accurate to 17 yards)

 

if its true - I fly 120 yards further than my measurements

[Newbie2020]

I think if your loft is mapped to the exact location and google earth specialises in maps etc surely the co-ordinates need to tally? One if not both ae definitely wrong which in this day and age of technology is just poor!! I seem to be in your boat redcheq and flying at least 60 meters different to my actual loft mapping!! Not really acceptable is it???

there was a thread on here about google earth coordinates a while ago and nobodys showed there long lat to be correct. I suspect it is more to do with google earth than Union coordinates, you can always check your own on an ordinance survey map!

Google earth is based on a satilite which moves as does the earth, so there is bound to be variations.
