This question already has an answer here:
Using QGIS 2.16.3, I wish to create a buffer zone around a single point in my multiple point file with a fixed radius of 5 km. Therefore, I made a selection and created a new layer only containing this point.
Next, I used Vecor -> Geoprocessing Tools to create a buffer zone with a fixed radius. Interestingly, the result is an oval buffer zone instead of a circular one, thus the radius is clearly not fixed, but flexible. What do I have to alter to make the bufer zone circular?
I have attached pictures of my input in the buffer zone tool, as well as a picture of my result.
