I'd like to create custom buffers in QGIS. Each buffer will surround a point. The buffers don't overlap. And each buffer has to have two constants:
There is a 50m radius space around the point which is within the buffer.
The buffer as a whole covers 10 acres.
The shape of the buffer will vary from buffer to buffer, so this detail is immaterial. What's important is, the buffers cover ten acres, including the 50m.
The above illustration is an example of what I'd want the polygons to look like, they can be of any shape in the world - so long as each one covers, in total, 10 acres.
