# Hike&Fly Peaks Switzerland

Fetch information about paragliding flights from alpine peaks.

Map: https://dbrgn.github.io/hnf-peaks/

## Prerequisites

- Bash

- PostgreSQL + PostGIS

- Python 3

- The following Python packages: beautifulsoup4, psycopg2

## 0: Start services

The easiest way to run PostGIS is through Docker:

    docker run -d --name hnf-peaks-pg \

          -e POSTGRES_USER=$(id -u -n) \

          -e POSTGRES_HOST_AUTH_METHOD=trust \

          -p 127.0.0.1:5432:5432 \

          docker.io/postgis/postgis:16-3.4-alpine

## 1: Download OSM Data

This will download the OpenStreetMap database and extract all peaks with an

elevation >1000m:

    ./1-load-osm-data.sh 

## 2: Query XContest

This will process all peaks and query XContest for the number of flights that

launched from within 350 m around the peak:

    export XCONTEST_USER=...

    export XCONTEST_PASS=...

    ./2-query-xcontest.py 

The data will be written to a file called `data-YYYY-MM-DD.csv`.

**WARNING:** X-Contest does rate limiting, so unless you are whitelisted by

them, you will probably get blocked after a while. Furthermore, do not run this

command on the evening of a hammer day, choose a time when XContest is not

busy.

## 3: Postprocess Data

To calculate some aggregations:

    ./3-postprocessing.py  pilots 

To generate GeoJSON from the data:

    ./3-postprocessing.py  geojson
