The tricky task of drawing a representative aerobatic box at a specific location over a fully detailed ground map has just got much easier with the release of an excellent new App from British unlimited pilot Steven Bakhtiari. Next time you have this job just point your browser at https://box.contest.aero/ and follow the instructions. Judging positions at 150m from the box edge are optionally switched on, the box can be adjusted in rotation, and repositioned by clicking at a revised centre spot.

Here is a typical representation of the result. You can also send the exact location / image to a colleague by copying and sending the full browser address - the recipient clicks the link and hey-presto the same result is shown.
