1. ## What we ( the GAGB) are attempting to achieve

A well written and well thought out argument and one that I fully agree with.
2. ## Congrats to Dorset Gal!

I am sorry that I could not be there in person to see you do your bit but I am working in Singapore at present so only saw some glimpses on CNN. My wife has told me she managed to record your bit and say there is some good footage of you. Well done to both of you!!!
3. ## Fairly Interesting Observation

Take a look, Sat was directly overhead. These were the two with errors N 51° 38.097 E 000° 33.380 & N 51° 35.922 E 000° 33.941. This was one of the ones which was spot on N 51° 39.214 E 000° 32.529. Essex is pretty flat so there's not much difference in height. I was just trying to offer an explanation as to why I would trust my GPS over Google Earth. Interestingly, if you plot your second position in GE you can see that the aerial view is not directly overhead. About 150m to the west of the posiion is a pylon and you can see that the picture was taken from the SW of the pylon otherwise it would appear symmetrical from directly overhead (ignore the shadows). Given that the elevation here is only 30m or so the error caused by the perspective would only be minimal. An interesting idea would be for you to find a lighthouse on the Essex coast and obtain its position from the Admiralty Light Lists and check your GPS against that. Have a day at the seaside and try it every hour or so and see if/what error you get. You could also see how the lighthouse looks, positional wise, on GE.

5. ## Wherigo......

I have just spent a little time trying to put together a cartridge and have a couple of questions about the Player. Am I correct in (1) assuming that the Player hunts out the GPS and that there is no way of telling the Player where to look for it and (2) there is no way, other than textual, of indicating where you are in the real world in relation to a Zone? To explain my question (2) a bit better... Can you display the geographical locations of zones on the PDA Player and see where you are in relation to them? I am sure I am missing something really elementary here!
6. ## Wherigo......

Sounds very complicated!
7. ## Most found caches in the UK

Is there a list anywhere of the most found caches in the UK? One of mine has just gone through 500 and I wondered where it stood in the league. Obviously, it is about the numbers.
8. ## List of UK Counties

Well done guys. It won't please everyone but appears to be an acceptable solution to a very difficult problem.
9. ## I need an alternative to BeeLineGPS (I think)

If you are using a Sirf III GPS receiver ensure that "static navigation" is turned off. There are various utilities that can allow you to do this.
10. ## Visiting London

Slightly off-topic, but... I do not know how long you intend to stay in London and how much travelling you intend to do but I strongly suggest you consider getting Oyster cards as they can save you a lot of money. The link shows the fares for cash and for using the card. After getting the card(s) there is no more queuing at ticket offices. If you do not use all the money on the card(s) you can always give them to someone else who may be coming to London. It is also worth remembering that, although London is a big place, the tourist areas are not that far apart and it si quite often quicker to walk than use public transport.
11. ## Forum Moderation - Is it flawed?

I personally think that the forum moderators do a first class job considering that (a) they also have a private life ( review our caches in timely manner © probably do not have the luxury of using the "ignore" feature that I make copious use of and (d) must get bored witless with some of the drivel they have to read! Being impartial is extremely difficult and fence sitting as not as easy as some folks think it is. The problem would appear to arise when two moderators have a different opinion and fall on each side of the fence, as appeared to happen with the "Sun" posting yesterday. From my recollection one moderator posted, letting the thread continue, whilst another, obviously writing at almost the same time, closed it. Posters to the forums do not help the moderators by wandering off topic and I think it is in those threads that things tend to generally get a bit heated. Heated debate is good provided that it does not decline to personal attacks and insult swapping. I would tend to let the threads go until that level was reached. The (possibly) bigger issue in this case is "what are these forums for?" In the post that kicked this thread off the OP said it was off-topic so why post it on these forums? It then later appeared to transpire that the issue might have been on topic but the reason why was evaded by "those in the know". I look at the forums now and again to get a feel as to what is happening in the Geocaching world but do not mind using the "ignore" option to pass something that does not interest me. Finally, the other thing that occasionally happens on the forums, and could possibly embarrass the moderators, are postings that poll for opinions as to whether something may be allowed or not. If I have a query, I contact my local reviewer and let him know what I am planning. I always get a response in reasonable time and I always take his advise on board - simple! No confusion from several posters giving their often polarised views. When a private response from my local reviewer takes a day or two I know that he has entered into discussion with the other reviewers. As Lacto said in his opening post, they are chosen to do the job for their experience. Thanks guys - keep up the good work.
12. ## Time For Lordelph

Not working for me either and I have the same versions as Dino.
13. ## Google Earth or GPS?

You will also need: 1. Experience in removing or minimising the errors in the sextant 2. Nautical Almanac Data 3. Sight reduction tables 4. Nories Tables (or equivalent) if you are not going to use sight reduction tables 5. A highly accurate watch chronometer 6. A mercury bath to create an artificial horizon 7. Knowledge of navigation for using a sextant. I suppose that there is software available today that does away with items 2 to 4. The last time I used a sextant was just as GPS was being introduced to Merchant ships and was prior to 1984. The tables, formulae, etc that I used to use were not based on WGS84 but on the assumption that the earth was a sphere. Can anyone tell me if the formulae that is used today, for celestial navigation, is for WGS84 and point me towards it? Did sextant development stop with the readily available GPS system?
14. ## UK MEGA EVENT

Why not have the event the week after "The Great Yorkshire Show" (8th-10th July) and make it a CITO event as well. You never know, the GYS organisers may offer incentives to help with the clean-up. Is there such a thing as a Mega CITO event?
15. ## Published cache but a delayed Place

For something that is not the norm - such as this suggestion I would have thought that mooting it with the revieweres would have got you an answer! If I remember correctly, when a cache is submitted for review you have to place a check mark in the submission saying that the "listing" is active. If you do not check the box the reviewers do not see it. If the "listing" and "cache" being active are one and the same only a reviewer can say.
16. ## Michael Bradshaw

Through a bit of detective work I have tracked down Michael Bradshaw, who is not a cacher, and have returned his possessions to him. He had stopped at The Winchester Geese cache to read the ribbons on the gates. Please lock this thread.
17. ## Michael Bradshaw

Thanks for the suggestion but I have tried that without success.
18. ## Michael Bradshaw

Whilst caching, today, I found something belonging to a Michael Bradshaw. As it was less than a metre from the cache I am hoping that he is a cacher. The cache in question was "The Winchester Geese" in south London and I think Michael may live in north London. Thanks.
19. ## Tricks 'n' Tips

Away from the math and back on topic... My hot tip from today. I use a bluetooth GPSr with a PDA and the GPSr fits in a pouch on one of the straps on my rucksack. Cardinal sin - don't take your rucksack off and wander around with just the PDA!!! Plonker of the century or what?
20. ## Are micros the new virtuals?

I assume you have not tried this one
21. ## Tricks 'n' Tips

My maths teacher taught us "Some Officers Have Carts And Horses To Order About" to remember this one - still can remember 40 years later but I do use it most days! For those to whom this means nothing: Sine = Opposite/Hypotenuse Cosine = Adjacent/Hypotenuse Tangent = Opposite/Adjacent I'm struggling now to see how this is a tip or trick but a couple of my caches require this knowledge!
