Now, anyone know anything about getting the gsak info to my palm pilot?
I'll go out on a limb here and say that most [a lot of?] folks use cachemate [see post above for link]. Once installed on your PDA, you can transfer info direct from GSAK.
First, open the database you want, and if necessary, run a filter to get the caches you want. Then, click on File->Export, and on the dropdown menu, the fist option is to transfer to PDA using cachemate.
I guess that you need to overcome the learning curve for GSAK--I'm still learning, and if you follow these forums, you'll see that a lot of other GSAK users are still learning, too.
Hope this helps...

No link, but the math isn't hard.
If you know the two coords, then you know the distance between them, and the bearing from one to the other, right?
Let's assume for simplicity that they are 100 ft apart, and point 'A' is due west of point 'B' i.e. the bearing of B from A is 090°. Let's assume further that the third point, 'C', is in a northerly direction from the line joining A and B.
The third and final assumption is that your GPSr can project a waypoint--if it can't, you'll have to resort to a compass.
From point A, project a bearing that is 60° less than the bearing of B...in this case 030°. Along that line of bearing, add your waypoint 100 ft away. If you're starting from B, add the 60°. If the third point is in a southerly direction from the baseline, reverse the procedure above [i.e. from A, add the 60°, and from B subtract it].
Hope this helps...

Java and javascript have absolutely nothing to do with each other. Javascript is implemented entirely within the browser, so it's not possible for the browser to be incompatible with your javascript. (It is possible for it to be incompatible with your Java installation.)
In Firefox, click Tools / Options, then in the resulting window click on "Content". This will show you two separate checkboxes, "Enable Java" and "Enable JavaScript." You want JavaScript to be enabled when using geocaching.com.
[At least, that's how the menu is arranged in Firefox 1.5. If the new version rearranged windows again, just sniff around for the javascript option.]
OK, That's what I did. When I looked in the location klossner indicated, both Java and JavaScript are enabled. I just looked at another cache page and when I clicked on the Encrypt/Decrypt link, I got a new page, rather than a refresh of the original page.

Do you have javascript turned off?
When I first read this, my immediate response was, "Yes, of course I do!", but then I remembered that when Firefox upgraded itself a couple of weeks ago, I got an incompatibility message regarding the current version of Javascript, so I assume the answer is now "no".
I guess I'll have to check again on the Java site.
Cheers,

Slightly off topic, but still dealing with encrypt/decrypt is that when I click on either, the changed page is shown in a NEW browser window and the page also jumps to the top. Is this as it's supposed to be?

Shearzone, you got it! The latitude of each meridian crossing is then plotted on a Mercator chart to give a series of rhumb lines that approximate the great circle.

First of all, apologies for not responding sooner--weekend--
Now, for today's question:
What property of a map/chart drawn on the GNOMONIC projection makes it useful for long distance navigation?

In addition to those already mentioned by Myrtlemoose, there is also Compass North. This is the direction one travels using a compass that has been corrected for both Variation [the angle between True North and magnetic North at a given location] and Deviation, the error caused by magnetically permeable soft iron in the vicinity of the compass. This second error, which can never be totally compensated for, is reduced by the placement of small magnets near the compass, as well as concentrations of soft iron, usually placed opposite the known concentrations on board to compensate for them. They are appear as a closed vertical brass tube [the Flinders Bar] and two spheres, usually placed on either side of the compass, called Lord Kelvin's Spheres [sometimes irreverently and vulgarly called Lord Kelvin's balls].
This third North is usually found on board ship, and although marine navigators usually use a gyro compass [which indicates the direction of True North], there is a legal requirement for all ocean-going vessels to carry a Magnetic Compass, properly compensated, and with a 'deviation card' showing the residual deviations which could not be completely counteracted.
Sorry for the long-winded explanation; my teaching experience got the better of me!

Hi Gill...
I've just completed your survey, and have one suggestion: if the answer to Q38 regarding blogging is negative, the respondent should then jump to Q41.
Good luck with your thesis!

I haven't been stopped myself, but while caching a few months ago, I found a log that was signed by a member of our local police service. Seems a guest at the nearby Delta hotel, which overlooks the cache site, saw some "suspicious activity", and reported it. The constable checked out the cache, signed the log, and replaced it as found!

I think, but have not verified, that it depends on how you send the info to the PDA. Like you, I have recently started paperless caching, using a Palm Z21, GSAK and Cachemate. The first PQ I downloaded, I opened in GSAK and Cachemate separately, and, like you didn't get al the info transferred. After exploring GSAK at bit, I found that you can export a database to the PDA directly from GSAK. When you do it this way, everything that shows up in GSAK is transferred to the PDA, including any notes you have made in GSAK, like corrected coords, etc. The exporting process opens the HotSync program and saves the exported file ready for the next HotSync you perform.
Cachemate is still needed, but only to reside in the PDA to enable it to read the incoming file.
Hope this helps...

You'll pardon the sarcasm, but my heart bleeds for you folks who drive gas-guzzling SUVs & 4WDs. Gas here in Nova Scotia is currently $1.21 CAD per litre. Let's see...at 3.78 litres to the US gallon, that's $4.57 CAD per US gal. Oops, I forgot! Our dollar is only worth $.925 US, so that's $4.23 US per US gal. I guess that at those prices, no one up here should be caching, unless it's for urban micros that we can walk to...

OK Stroover...I'll give you the go. However, if your course is either East (090°T) or West (270°T), by your definition, it can't be a loxodrome, as you'll NEVER reach the pole!
BTW, thanks for the clarification, CA!

I think that it would be desirable to be able to 'cherry pick' caches to be downloaded. It's inefficient to do so on an individual basis, so of course a PQ is the way to go. HOWEVER, in order to do this for a random selection of caches, you still have to make individual bookmarks to a particular BM file, and then run your PQ. How nice it would be to be able to pick several caches in a list and then with one click at the bottom of the page, bookmark them all into the same [pre-created] BM file.
I note that when I list caches by any criterion, the option exists to download some or all of them--as the OP notes only in .loc format. A similar option should apply to premium members to be able to bookmark some or all caches on a page.

Thanks, Greywynd. I'll give 'em a couple more days. BTW, Stroover, if you haven't used any kind of a reference to confirm your answer, you can give it another try...
cheers,

CA,
I need some guidance here. As the OP, I guess you are also the Chief Arbitrator by acclamation. How long do I wait for a correct answer? If none is received, do I ask another, or pass it on to the closest answerer, in this case Stroover?

Nice try Stroover. close, but no cigar! Anyone else want a go?

(1) you googled, and i believe that's agin the Rules, and
(2) you still haven't told us what it is...

OK, here goes for another navigation-oriented question...
What is a loxodrome [sometimes called a loxodromic curve]?
-
If you alter your course by one degree, after having traveled 60 miles, you will be one mile away from your original destination. In other words, 60 x sin(1°) = 1 mi. [Actually, it's 1.04 and change, but close enough for government work

Solving Puzzle Caches

To quote Col. Potter of "M*A*S*H*" fame, "HORSE HOCKEY!!"
The coords given by Trailgator are just an example of the DMS output of Google Earth. However, if you cut and paste the DD MM.mmm from the puzzle, GE is perfectly capable of translating them, and putting you in the right place. TG's coords are in Georgia; you're right, but if you solve the puzzle, you'll end up in Texas, as you're supposed to.
I sat down and did this whole puzzle in about 20 minutes this morning. You 'go' a certain distance by using the ruler function in the toolbar. Click once on the given coords, then move in the appropriate direction--you do know which way 'due east' is, don't you--watching the readout in the ruler dialog box. when it reaches the given distance, click again.
As to zooming down to a given elevation, I'm not so sure. I just zoom in until I can see the required detail--doesn't matter to me whether it's 500m or 1500m; if I can see what's needed, that's fine.
Try it again, Wordnerd. It really isnt all that hard.
