Re: [Paparazzi-devel] Circle and surveying questions

[Pascal Brisset]

Hi Daniel,

note that you can define a "sector" as a polygon in the flight plan and 
you will get a C function to efficiently check if a point is inside or 
outside this sector (the code is currently limited to y-monotone 
polygons). The polygon is described as a clockwise list of waypoints.

   Example in http://paparazzi.enac.fr/wiki/index.php/Flight_Plans#Sectors

So you could copy the survey_rectangle code  and only replace the "cross 
the south or north border" condition by a "cross the polygon border" 
condition implemented with the "InsideMySector()" function.
