DonB,

Of interest, I am holding a Garmin eTrex Legend GPS unit in my hand as I am sending this post.

My current Garmin reading is:

28.00.790 N
82.18.238 W
accuracy within 14 feet.

DataStorm Admin. reading is:

28.0132 N
82.3038 W

I have input the Garman reading on the Tampa map coordinates and I am no longer on the map.

I will be back in about one hour and walk around the rally park, dodging the rain clouds and send you the readings.

Which do we believe? I would hope the Garmin with WAAS accuracy would be closer, but we need to work with each member's DataStorm reading also.

DonB,

I have just sent you an email with a number of the Garmin GPS data readings in several formats, i.e., RTF, XLS, & PDF that could be used to plot the rally park map.

Call me when you get a chance, will be out to dinner around 7:30 until 10:00. We stay up late so do not hesitate to call.

George

Those readings just about match, so it may be how you entered them.
28 degrees 0.790 minutes is 28.013166666 (28.0132)
82 degrees 18.238 minutes is 82.30396666 (82.3040)

I just fudged my latitude by one thousandths of a minute to put me in my RV space instead of over the fence line. . .

DonB,
I read Georges post and was going to tell him to convert degrees, minutes and seconds to decimals of a degree or vice-versa, but then I saw you already caught it. You'd be surprised how many people don't realize there's a difference. Made the same mistake myself once. See you all on Wednesday.

I have adjusted the map based on the readings that George gave me. That means that anyone who has fudged their position will need to do so again.

It appears that side-by-side-east-to-west sites are about .0001 degrees apart, which is the limit of the datastorm GPS reading. When sites are side-by-side-north-to-south, they are less than half that.

I expect to stop changing it at this point, as it is about as accurate as I can make it. I would suggest, for anyone that wants to fugde themselves into place, make changes on the order of .00005.

If you want to move left, add a 5 on the end of your longitude. If you want to move right, drop the last digit by 1 and put a 5 on the end (for example, 82.3039 would become 82.30385). To move north, add a 5 on the end of your latitude; to move south, lower your last digit by one and add a 5 (for example, 28.0137 would become 28.01365).

If anybody doesn't understand this, feel free to e-mail me and I will tell you what to change your reading(s) to.

I had noticed several people doing it, so I put a conversion tool on the page where the data is input.

Don, again you come to the rescue of all. Great work. I'll have to go back to bonehead math class, again!

Hi To all,

I wish I was at the Rally, but alas it was not possible for me to attend, although, in the future, I hope there will be one on the west coast, where I could possibly attend. I hope all of you have a great time and post what you have learned, and your experiences, so that we can all share the adventure with you.

On another item, how can we see the "map" and all its iterations? I would love to see how everyone got to the rally, and how precisly you can show where they are now on the map.

After the rally, perhaps we could get a posting of how well the non DataStorm GPS units compare vs our DataStorm readings, including information such as; GPS unit manufacturer, model, source of supply, price, features, ease of use, availability, etc. This could be a great help to those of us who are considering such a product.

Any way, HAVE A LOT OF FUN, for the rest of us!

PS: I have tried to use some great avitars for my identity on this board, but I still can't get them show up on my profile, I see that on my update to my profile the avitar is in the box and I select to "use this avitar", but once I close the update page, it is gone! I will keep trying to figure out how to add one that is not on the generic list, it is clearly a learning experience, and I will figure this out eventually. (Any help is appreciated)

Rob Payne

Hi Rob. I'm not maintaining historical data, just the current listing. You can get to the maps in a couple of ways. First you can go through the "Show your location" link at the top right of any of these pages. That will let you put yourself on. If you don't want to show up, put 0(zero) for latitude and longitude. For those who want to be on the map, it is good to go in that way occasionally even if you haven't moved - it remembers where you are, so you don't have to enter any numbers, and it will update the timestamp to show you are still there.

The other way is to go in through direct links. The main map is at
http://www.datastormusers.com/showmap.cfm
and you can click so far on California or Florida for larger scale. On the Florida map you can click on Tampa to get the LazyDays map. Direct links for those three are:
http://www.datastormusers.com/showmapca.cfm
http://www.datastormusers.com/showmapfl.cfm
and
http://www.datastormusers.com/showmaptampa.cfm

I see that Scott is no longer south of Iceland, but can be found floating in the Lazy Days pool.
