Given is a map with an airport. Within a distance of 5km around the runway there is a so called no fly zone for drones (in Switzerland). I want to show this zone in a map.
What I would like to do is the following:
- Add a polygon around the runway (that's ok, exept that I prefer to enter the exact geo-position in decimal format instead of clicking the map).
- Add a second polygon that is exactly 5km from each side away
- Crop the corners, because these are now more than 5km away from the runway corner. To simplify one more point at 45° would be ok; I don't need a curve.
How can this be achieved with QGIS? Or better with another tool?
I have tried using buffer as suggested in the answer and this is the result:
Why does the buffer appear distorted instead of a uniform 5km?
