Hi,

are there any open/free tools to datamine on database of many IGC files?

There is a threat that the free airspace for gliding in Slovakia is going to be significantly restricted. We need tools which help prepare arguments about airspace usage and frequency of our flights.

If I was starting from scratch I would probably try to import all the flights into a GIS database (PostGIS) and do the data cleaning and queries there. Does anybody have experience with this?

Thanks for you help,
Tibor Arpas
