Newbie Confusion..

Hello everyone,


As the title suggests I'm new to all this, so new I don't have a GPSr yet, Santa's bringing me one, I do however have a set of 1:25,000 OS maps and the Fugawi CD's containing the 1:50,000 scale versions of the OS maps.


Here's my confusion, I found the cache nearest ro my house (Roman Around) and looked it up using the british grid sysyem on the 1:25,000 map, the cache description lists it as being on the old roman road and sure enough, there it is:




However when I load the Fugawi OS maps into my PC and insert a waypoint based upon the coordinates given, I get this:




Now either I'm not entering the coordinates right (more than likely..) or the Fugawi software is totally innacurate.


Can anyone shed some light on my problem/stupidity?


Many thanks,

Also check the coordinate system each program is using. There is a whole host of different coordinate systems based on different map projections (getting the round world onto a flat piece of paper.) The two most common are WGS84 and NAD27, most digital formats use WGS84, thats what all the posts here are in, but if a program is written to work with paper maps it may use NAD27. There is an 81 meter E/W difference between them as well as some N/S difference.

I looked back at this real quick and saw Jamie Z's post. Looks like he's right, I didn't even really look at the pictures. Just posting again to add something to his post: If the progam you are using does not accept you entering the decimal values into the minute field, just multiply the decimal minutes by 60 (.401 x 60= 24.06) to get the seconds. So 0 deg 20.604 min equals 0 deg 20 min 24.06 sec. If the program wouldn't accept decimal minutes it most likely won't accept a decimal value in the seconds field, so you have to round 24.06 down to 24 so you do lose some accuracy with that program but I guess that might be a gauge of how good the program is.


Sorry had to edit (twice) for spelling.

According to your bottom picture, you are not entering the coordinates correctly.


Thanks Jamie & Ol'Gem, you nailed it, that's why I left that info in the screen grab in the hope I was doing something wrong..


I did some practising with coordinates from caches on this site and coordinates thrown up by multimap and I can get the software to pretty much pinpoint the right places..


Now I can happily enter all the caches within easy strike distance ready for the GPSr .. come on Xmas.. :D


Thanks again!

Reading my mind there GPSax.. if I get all my chores out of the way tomorrow I'm going to spend the pre-xmas onslaught knee deep in mud looking for tupperware.. I need to find a couple to get the ettiquette before I stash mine, there's a huge gap on the map crying out for something to be hidden there.
