Hi there,

I am currently in the trial period and started my first planning today. Unfortunately I couldn't set my home airport as it is a glider site. While finding a rough circle with something in it I recognized some other glider sites that are no more available (because they are closed in the meantime). I am wondering whether some sites are shown precisely and some aren't. What is the source of data as it seems to be not accurate.

Please help out,
joseffe
