Technical description

• All data is collected from the OGN network (Open Glider Network).
• The real time feed is achived by letting the browser connect to our own APRS-IS server through a websocket connection (with no intermediate database-server).
• The heatmap that is shown when you zoom out is generated once every hour.
• The initial map position is based on your IP address. This is achived by using the GeoLite2 data created by MaxMind, available from http://www.maxmind.com.
• The geographical data like city locations is received from http://www.geonames.org/.
