IGC to Google Earth converter

igc2kmz IGC to Google Earth converter

igc2kmz converts paraglider and hang glider track logs into Google Earth KML format with lots of features, notably:

• track colored by altitude, climb rate, ground speed and total energy
• shadow feature makes it easier to judge the track's altitude by eye
• animation of the flight
• photos automatically placed where they were taken and with an optional comment
• XC optimisation output
• altitude graph and high and low points labelled
• thermal and glide analysis
• time marks

It's used by the following XC league servers:

• Leonardo
• UK National XC League

Just upload your flight to one of these and you can download your flight in Google Earth format without having to install any extra software on your computer.

It is designed to run on XC league servers, and as such is not designed to be directly used by pilots.

Requirements

• Python version 2.*, not version 3.0

Get the code

Download either the zip archive or the tar.gz archive.

Unpack this archive somewhere.

If you want to track development then you can checkout the source code with git instead of downloading an archive:

git clone git://github.com/twpayne/igc2kmz.git

Run it

Change to the directory where you unpacked the archive and run:

bin/igc2kmz.py -i <input-filename>.igc -o <output-filename>.kmz

Customise it

You can set various parameters via the command line, including the time zone offset in hours relative to UTC. For example, use -z 2 for Central European Time during the summer. For individual flights you can override the pilot name and glider type (otherwise they are taken from the IGC file), set the line color and width, add optimized XC information and photos with comments. Run bin/igc2kmz.py --help for a full list of options. For example use, look at the Makefile.

Rebuild the examples

You can rebuild the example files with the command make examples. This will build the olc2002 flight optimizer, optimize a number of flights, and create the KMZ files in the examples/ subdirectory. Be warned that the flight optimization step can take a long time (30 minutes on a 2.4GHz Core 2 Duo).

igc2kmz's Issues

Simple web frontend draft

Hi, thanks for the very useful tool for all paragliding people, I've created a simple php web frontend for igc2kmz, it is just a hack job, still posting here for your reference:

https://github.com/cyberorg/igc2kmz

README - Place this folder in Linux web server's document root, open http://localhost/igc2kmz/ Make sure uploaded_files folder is writable by web server user. See http://prime.cyberorg.co.in/igc2kmz for example.

igc2kmz on Leonardo produces empty KML file error

Hi Tom,
I've noticed for a while now that your excellent igc2kmz part of Leonardo has not been functioning, specifically the "most detailed, bigger size" part. I found it so useful when trying analyse where I went wrong on a flight. Is there any hope of seeing it brought back to life?
Thank you for all your excellent work for the paragliding community which I hugely appreciate as a very mediocre pilot.
Best wishes,
Chris

Leonardo Igc2Kmz not working

The attached igc file does not generate the kmz file.

2016-09-11-XCM-ELQ-01.igc.txt

Also the leonardo file http://www.paraglidingforum.com/leonardo/flight/1501562#

Both the igc files are created using oudie 4.

can't parse HFDTE records with "DATE:" in them

HFDTE records now contain "DATE:" e.g.:
H F DTE DATE: DD MM YY, NN CRLF
the regex HFDTE_RECORD_RE ignores these records.

Default output filename

Hi Tom,

when no output file is given by default filename should have same name (without extension) than input

python bin/igc2kmz.py -i examples/MyTrack.igc

should output MyTrack.kmz (instead of igc2kmz.kmz)

fileName, fileExtension = os.path.splitext('/path/to/somefile.ext')

could help

I also wonder why using this -i flag (option and not 1 positional argument).
A flag could be use to define if this positional argument is a IGC filename, an URL ...

You might have a look at click http://click.pocoo.org/
it's a very convenient package for CLI parsing.

C records are not taken into account

C records are not taken into account when ouput a kmz file.

igc2kmz (most detailed, bigger file) issue

Hello,

Once you click to download the most detailed file, it downloads a 0 KB file. At first I thought it was user specific, so I tried several users and random tracklogs. All of them seem to have the same issue and the downloaded file is always of file size 0KB. Once it launches in google earth, it gives a no information in file error.

thank you.

Shoaib.

Batch convert IGC to KMZ

Hi Tom (again),

it will be nice to provide a batch convert feature.

glob can help https://docs.python.org/2/library/glob.html

I have a directory with several IGC files. I would like to create a KMZ file (one per IGC file)

in such a case -o flag should be an output directory

Kind regards

Invalid C record

Hello,

I output from Condor Soaring an IGC file

$ python bin/igc2kmz.py -i 20150509.igc -o 20150509.kmz

raises a warning

WARNING:root:20150509.igc: invalid record 'C210615130110210615000003'

It will be nice if igc2kmz could support these C records and display both circuit (C records) and also track (B records).

An example of such a file

Total energy compensation (unit)

Total energy compensation should be named "climb (with energy compensation)" and should be given in meter per second (as climb)

see #1

Color is lagging

I noticed that color (Colored by climb) is lagging.
See screenshot you can see that color is blue when altitude is increasing
which is odd because positive vertical speed should be red.
Maybe you could numerically shift data points.

Formula to calculate climb with energy compensation seems to be false

Hi Tom,

As I said in #5
Formula to calculate climb with energy compensation seems to be false

Kind regards

Colored by compensated vertical speed

Hello,

it will be nice to add a new kind of color for track.
Track "Colored by compensated vertical speed"

You need to calculate total energy (kinetic energy + potential energy)
see https://en.wikipedia.org/wiki/Variometer#Total_energy_compensation_in_theory

It's very useful for gliders pilots.

Kind regards

Sébastien
