I use a lot of stuff off GPSFileDepot when making custom topos. It's handy, but can take a little doing to get exactly what you want since they're primarily designed to load straight to a GPS.

Hope this helps someone out:

When I was doing Search and Rescue we would do this on almost every training . We would measure off a course on level ground and pace it and count on the double step, we would measure a 100 meter line going over hilly brushy terrain. This would give a good indicaton of the difference in the pace counts on different terrains.

I ran across this bit of software :

you place yourself anywhere on the map and it gives you a graphical panorama of your surroundings, with bearings, distances, etc.

Do we have anything similar in North America?

Thanks.

Thanks.

I heard some time ago that Google was working on something similar to the Google street view, but 100% coverage across the USA starting with the Grand Canyon.

Greats posts guys, I am really enjoying this thread and brushing up on nav. Moving from flat NJ to mountainous CA almost a decade ago, hiking ridgelines around hills and mountains creeps me out a little because its so easy to get turned around 50x. Its just something that I am not accustomed to yet.

Ran across this resource yesterday doing some research.
Skimmied through this thread and did not see it, so here it is.

I'd like to ask a quick question on delineation. i know there are sayings like east = least and west = best, but I want to just understand it in a logical way in my mind.

If I wanted to align my compass to true north and my map had this 12.5* delineation mark on it, I would align my compass with the North needle, then move it 12.5* to the left (counter clockwise) to point to true North, correct? Its been a while and I need to brush up on a few things, thanks

Yeah the compass will point to Magnetic North, but your map and its lines are in True North (North Pole).
If you lived on the other side of the Agonic Line you'd adjust opposite.
