Version 1.2 of the open source (and free) flight data analysis and
visualization Software GPLIGC has been released and is available for
download at:

http://pc12-c714.uibk.ac.at/GPLIGC/GPLIGC.php

GPLIGC can be used with Linux, Unix and Windows.
So far only IGC flight data file format is supported.

Requirements:
GPLIGC: ActiveState ActivePerl, Gnuplot (both are freely available)
openGLIGCexplorer: Hardware accelerated openGL recommended.

Features of Version 1.2 (released 22 aug 2003)

GPLIGC (analysis)

* free software (open source)
* supported platforms: linux, unix, windows (95?/NT?/98/ME?/2000/XP)
* Altitude- (gps,baro), Vario-, Speed-, Engine Noise Level-Plotting
(with Gnuplot)
* Histogram plotting of speed and vario (with Gnuplot)
* Indicated airspeed plotting (if supported by logger)
(with Gnuplot)
* 3D Track plotting (with Gnuplot)
* All Gnuplots can be made as postscript, eps,png, fig, pnm
* Information about pilot, plane, task (if set in logger)
* Task distance and task speed calculation
* FAI triangle detection
* Online Contest 2003 task optimization
* Online Contest 2003 “.olc”-file output
* 2D track and baro view. Every logged value can be displayed.
* Absolute altitude calibration
* Thermal statistics
* Glide-distance statistics
* FAI “photo”-sectors and 300, 500 or 1000m cylinders.
* Units supported: m/s, knots, ft/min, km/h, m, ft, km, nm

openGLIGCexplorer (visualization)

* free software (open source)
* supported platforms: linux, unix, windows (95?/NT?/98/ME?/2000/XP)
(?=not yet tested)
