View Full Version : Altitude oddity - CN2 w/ .stx file format


March 14th 16, 11:01 PM
I have a new CN2 and I've loaded a (what I believe) is a carefully formatted .stx file. Tab delimited.

Most of the waypoints show the correct positive field elevation. A few (seemingly random points) show a negative number. Specifically -3277.55916.

The altitude in the file is 320. The column header is Elevation[Feet].

Anyone else experienced this and if so, know what the cure is?

Thanks,

Mark

It's almost certainly a file format problem.

Take a look in a text editor that displays all non-printing characters. Notepad++ works.

Maybe, in 50+ years.

Notepad/wordpad have been around sorta since "the dawn of the PC" (think DOS stuff..... very basic PC stuff). They work and MS has not FUBARED them as far as I can see.

Now, you want to talk about some MS OS's, that is a totally different discussion.

What would you propose? Keep in mind, it has to work with the software you're using, notepad/wordpad work with pretty much EVERY MS OS.

Please note that "Notepad++" is not the same as "Notepad".

"Noteped++" is a free piece of software that is not affiliated with Microsoft, and is way better for many situations (especially for programmers and other technical work; although it's just fine for casual users as well).

You can download versions of Notepad++ for several different OSes, including both Windows and Mac.

<thanks Noel>

When editing or creating your own waypoint files (regardless of format) a good practice is to use a known good waypoint file as a template to start from.

You can learn more about the STX format here

http://soaringweb.org/TP/stx.html

However, DON'T USE THE EXAMPLES on that page to create your own files. They won't work. As a colleague puts it "The good thing about STX is it's nice and flexible. The bad thing about STX is it's nice and flexible." The examples just warned against illustrate this flexibility nicely but will cause problems in your flight computer. Please use instead a waypoint database intended for ClearNav chosen from one of the many world wide soaring sites on the WWTPE.
