More than fifteen years ago airspace-v.com was launched. A web site with map data for general aviation. In the meantime resources for mapping and for aviation information have changed and improved a lot. Web site airspace-v.com is under refurbishment now. It is becoming an application of OpenStreetMap showing information collected from public sources on the net. Here you can see which information is presented on the map and you can learn a few implementation details for efficient database querying of distances and a file based location name lookup that is extremely fast.
