# Building
In this repo, clone FGdata.
Save the [dsf2aptdat.py](https://github.com/mherweg/d-laser-fgtools/blob/master/dsf2aptdat.py) as well in this repository.
Then build the container with `docker build --tag aptupdate .`

# Usage
You need a bunch of working directories under a `<path>` of your choice:
* logs
* output
* data
* tmp
* work
* stg

You need to put the elevation data into this.
This requires the .arr.gz files.
Those are expected to be put under work/SRTM-3/
And are supposed to have the structure of `<10x10 degree area name>/<1x1 degree area name>/<tile name>.arr.gz`

Start the container with
`docker run -it --name aptupdate -v <path>/logs/:/aptuptd/logs -v <path>/output/:/aptuptd/output -v <path>/data/:/aptuptd/data -v <path>/tmp/:/aptuptd/tmp -v <path>/work/:/aptuptd/work -v <path>/stg/:/aptuptd/stg --rm aptupdate bash`

In there all you should need to do is run `./aptupd.py`

You find the output in the respective directory.
under data, you'll find a file `airports-done.json` after the first run.
This keeps track of the built airports and their version to only run updates on airports which got changed on the xplane gateways
If you wanna rebuild an airport, open the file, look for the airport in question and change its id, then re-run the process again.
