Euroscope ESE to VATGlasses convertor

File structure

The final target file is outputs/lf.json. Each section of that json are generated in separate files first:

lf.json section	File	Type	Script
airports	outputs/airports.json	Dynamic	generate_airports.py
airspace	outputs/airspace.json	Dynamic	generate_airspaces.py
callsigns	outputs/callsigns.json	Static
groups	outputs/groups.json	Static
positions	outputs/positions.json	Dynamic	generate_positions.py

The script merge_all.py takes all 5 above files and merge them into outputs/lf.json

Install the prerequisites

• Install the required python libraries:

pip install -r requirements.txt

• Copy the latest Euroscope ESE files in inputs\LFXX.ese

Generate the target files

• Run the following command to generate the outputs/airports.json

python generate_airports.py

• Run the following command to generate the outputs/airspaces.json

python generate_airspaces.py

• Run the following command to generate the outputs/positions.json

python generate_positions.py

• Run the following command to generate the target outputs/lf.json

python merge_all.py

Test the results

You can use the script export_geojson.py to generate GeoJSON file and visualize them with https://geojson.io/

usage: export_geojson.py [-h] --input-files [INPUT_FILES ...] [--output-file OUTPUT_FILE] [--show] --flight-level FLIGHTLEVEL [--positions [POSITIONS ...]] [--sector-regexp SECTOR_REGEXP]

optional arguments:
  -h, --help            show this help message and exit
  --input-files [INPUT_FILES ...], -i [INPUT_FILES ...]
                        VATGlass input file
  --output-file OUTPUT_FILE, -o OUTPUT_FILE
                        GeoJSON output file
  --show, -s            Show on geojson.io
  --flight-level FLIGHTLEVEL, -f FLIGHTLEVEL
                        Flight Level
  --positions [POSITIONS ...], -p [POSITIONS ...]
                        Space separated list of position codes
  --sector-regexp SECTOR_REGEXP
                        Regular Express to filter sector

For example:

• All positions at FL300 (will generate only CTR positions)

python export_geojson.py -i outputs/lf.json -o output.geojson --flight-level 320

• PAR and PG approach at FL180

python export_geojson.py -i outputs/lf.json -o output.geojson --flight-level 180 --positions PAR PGN

• Marseille, Nice Approach and Tower at 1000 feet

python export_geojson.py -i outputs/lf.json -o output.geojson --flight-level 10 --positions MM MNA MN

GeoJSON exports

The current VatGlasses data are pre-exported in GeoJSON format and stored in the exports folder. You can use the following links to visualize the data in geojson.io:

FL	x00	x10	x20	x30	x40	x50	x60	x70	x80	x90
3xx	FL300	FL310	FL320	FL330	FL340	FL350	FL360	FL370	FL380	FL390
2xx	FL200	FL210	FL220	FL230	FL240	FL250	FL260	FL270	FL280	FL290
1xx	FL100	FL110	FL120	FL130	FL140	FL150	FL160	FL170	FL180	FL190
0xx	FL000	FL010	FL020	FL030	FL040	FL050	FL060	FL070	FL080	FL090
