Distance rings around waypoint

[flying_barista]

Thanks to all who have created oruxmaps. I have been using oruxmaps in competition hot air ballooning. One feature that would make it even better for me is the ability to draw four accurate distance circles around a waypoint.



One of the tasks in a competition is to fly the balloon and keep it within a three tiered set of concentric circles. It is like trying to fly within a giant three tiered wedding cake. The base of the cake is 2-4km in diameter, the next layer is 1-2km and the top usually 1km in diameter, each layer is usually 500 feet high. In most cases the pilot achieves a higher score the longer they stay in the top narrow layer, and sometimes once the balloon leaves the wedding cake it cannot re-enter, so precision is very important to a good result.



If I could drop a waypoint and then add these rings around it that would be awesome. Thanks for considering my request.
