Dang I forgot to get my ruler out for that airport to make sure the lines are straight!
Seriously I think I spent 20+ hours on that airport faithfully/meticulously tracing over the satellite image. You wouldn’t believe how much time goes into editing these airports.
The airport editing team does a fantastic job. You should see (1) how bad some of these airports are when we first get them and (2) how bad some of the satellite images are.
This airport was shared between Henrik and myself. We had to literally cut and paste 10 different aerial views and realign them for scale. Not every airport has a complete image therefore we have to scavenge what is available. I had this exact problem recently doing the EBBR refresh. The standard image is circa 2008 and the building areas to the north were distorted. Although we have a tool to help us we can only source satellite from Microsoft/Bing. Google has some great imaging but we CANNOT use it directly. When we do it is painstaking piecing together and adjusting.
