flugfeld

Maintained list of worldwide airfields with gliding activity with number of launches and link to OpenAIP.

This list is used internally at WeGlide to make airports appear on the map based on their 'importance' in the gliding world. We are syncing the number of flights from the airfields (uploaded on WeGlide) on a yearly basis.

Additionally, this repo contains all kinds of sectors/regions one might want to filter for. Contributions are always welcome!

OpenAIP Link

To link flugfeld to OpenAIP, you first need to register at OpenAIP and get a custom API client. Then you can download and parse the data

export X_OPENAIP_CLIENT_ID=your_client_id
python -m src.download

This command will use the existing mapping to WeGlide primary keys in pk_mapping.json and ignore new airports that are not present in this file. To also download new airports and assign new IDs, run

export X_OPENAIP_CLIENT_ID=your_client_id
python -m src.download --new

Missing airfield

If you find an airfield with gliding activity missing, there are two steps.

• make sure it is available on OpenAIP - if not, you can add it there
• add the missing row and open a pull request

Airfield not in administrative region

OpenAIP does not provide administrative regions. All airfields that are not in this list (For example EDDF) only belong to a country, not to a particular region. If there is in fact gliding activity on this airfield, you can add it here.

Number of launches

The provided number of launches is used as an indicator as to when airports appear on the map. If you add a new airfield, you may add a reasonable number. Number of launches is only important in comparison with near by airfields, as we compute a 'reign' parameter.

Naming

Naming of the gliding sites is following local conventions, so if you spot an error, please open a pull request.

Missing

Areas with missing information include:

• Russia
• South America
• Japan

This in parts due to airport information missing on OpenAIP

Sectors

The sectors.json file describes all sectors that do not match administrative regions. You may add relevant sectors of your choice. Just copy and paste the content of the file here or look at the GitHub preview to get an overview of already existing sectors.

Order of languages is German, English, French, Dutch, Czech, Italian, Polish.

Multi Regions

Multi regions are filters that combine multiple regions or countries. You may add relevant multi regions of your choice. Multi regions can contain both, countries and regions.

Tiles

To render mbtiles from geojson, we suggest using tippecanoe. Install on OS X with

git clone https://github.com/felt/tippecanoe.git
cd tippecanoe
make -j
make install

Then, to render the tiles

tippecanoe -Z3 -z14 -f -r1 -pk -pf -y id -y openaip_id -y name -y reign -y elevation -y runway_rotation -y lng -y lat -y radio_frequency -y radio_description -J airport_filter.json -o airport.pmtiles airport.geojson

To have a look at the tiles, run the code below and open localhost:8080 in your browser.

docker run --rm -it -v $(pwd):/data -p 8080:80 maptiler/tileserver-gl
