About
The goal of this website is to present Glider tracking data in a user friendly way. All data published on this website is received from the OGN network (Open Glider Network).
The OGN community project maintains a unified tracking platform for gliders and other GA aircraft. Currently OGN focuses on tracking aircraft equipped with FLARM, FLARM-compatible devices or OGN tracker.

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/.
