GPLIGC
GPLIGC is a software package for glider^* pilots. IGC flight data files can be analysed and visualised.
The package contains two components:
^*and all others who want to view GPS track logs (para-glider pilots, hang-glider pilots and even pilots of radio-controlled (sail)planes. See here)

GPLIGC, analysation
openGLIGCexplorer, 3d visualisation (can be used as a viewer for digital elevation data too)

GPLIGC can be used on Linux, Unix, Windows and Mac OS X.
The software can be used under the terms of the GNU General Public License. (GPL)

openGLIGCexplorer

Free software (open source, GPL-licensed)
Supported platforms: Linux, Windows, MacOSX, OpenBSD, FreeBSD, NetBSD, other unices
3d mode or 2d orthographic mode
Egocentric movement of the viewpoint, Swivel/rotate (move mouse with button pressed)
Digitised maps can be used
Digital elevation model can be used
Flight-track can be colourscaled (alt, speed, vertical speed)
Terrain elevation can be encoded with 6 colourmaps (2 of these colourmaps can be used at the same time)
Movable marker
Movie modes
Altitude above Ground can be displayed (if DEM data is present)
OpenAir(tm) airspace description files can be used
Stereoscopic view modes for "real 3d"
Offscreen rendering (only on Unix with GLX 1.3), hardware independent offscreen rendering with mesa
Can be used as a commandline rendering tool (e.g. for contest servers etc). See Online plotter

Requirements
GPLIGC is developed with (and for) Linux, but should work on most Unix systems too. Installation packages are available for Windows and Linux. For all other Unix-like systems (BSD's, MacOSX) you can use the Linux/Unix installation package, and an additional binary package for your platform, or just compile the binaries by yourself.
The Windows Version will need ActiveState ActivePerl (which is freely available) to run.
For running GPLIGC on Mac OS X, you need to have fink, to install Perl/Tk and Gnuplot.

GPLIGC needs

Perl 5 and the Perl/Tk module (on Windows platforms: ActiveState ActivePerl. If your Active Perl is version 5.10 or above, please install the Tk module from the Perl Package Manager)
The Gnuplot software. (GPLIGC will work without this)

openGLIGCexplorer needs

Hardware-accelerated OpenGL 3d (recommended) or OpenGL software rendering.
Digital elevation model (additional, but recommended)

Gentoo: Gentoo Linux users can install gpligc from the sunrise-overlay.
If you haven't used overlays before, just emerge layman, add source /usr/portage/local/layman/make.conf to your /etc/make.conf. Thereafter, sync the overlay-list: layman -S and add the sunrise overlay: layman -a sunrise. Now you can proceed with emerge gpligc.

Work in progress...
If you like testing of pre-release software, CVS-snapshots are available between the stable releases in the develop directory. For new features check the CHANGES and the most recent Manual

Bug reports, feature requests, patch submission, support requests
All this can be done with the Trackers on this page: http://sourceforge.net/projects/gpligc

Screenshots
Some screenshots can be seen at the screenshot page

Online plotter
Here you can upload your igc-files and see how the openGLIGCexplorer can visualise them. To the online-plotter

Digital Elevation Models available:
