Follow-up Comment #1, task #14639 (project gnuastro):
The region covered by most surveys can be represented with a convex polygon
(see gal_polygon_ordered_corners
<https://www.gnu.org/software/gnuastro/manual/html_node/Polygons.html>).
However, some larger surveys (like the GOODS or CANDELS) can have saw-like
borders which are represented by a concave polygon.
Therefore to be generic, this task is not independent of task #13658 (Work on
concave polygons too). Once `gal_polygon_ordered_corners' also works on
concave polygons (task #13658 is complete), the suggested program by this task
will also work on any generic survey field.
