Technical test, the goal is to get the network coverage at a specific address sent as a url query.

Based on data from https://www.data.gouv.fr/s/resources/monreseaumobile/20180228-174515/2018_01_Sites_mobiles_2G_3G_4G_France_metropolitaine_L93.csv saved here in script/mobile_network_data_original.csv

To install the project you need poetry :

poetry install

After insrtallation is successful, use this command to run it :

poetry run uvicorn network_api.api:app

The service use preprocessed data to found the coverage level for a query. The preprocess is done by the script convert_data.py which generate a json from the input csv.

The script does the following :

• Transform Lambert93 coordinates to standard GPS coordinates.
• Sort datapoint into list for each provider
• Build a 2d adaptative grid to optimize runtime operation

The adaptive grid works by spliting every area in four area recursively until each induvidual area only contains a certain amount of datapoint. Each area have a "outer limit" around it to make sure that any point inside the area can find the closest Datapoint.

To regenerate the file use this command :

poetry run python script/convert_data.py
