Hi, 

I noticed that sometimes the area highlighting feature of SkyDemon generates self-intersecting polygons. For example, this NOTAM:

D) DAILY 1600 - 2130
E) NIGHT VFR TRAINING FLIGHTS (NVG OPS)
BURGENLAND AREA OBERWART:
473120N 0161150E
472750N 0163820E
470250N 0160720E
470050N 0162850E
START HELIPORT OEAMTC OBERWART LODO
PARTICIPATING HELICOPTER: OEXEK OR OEXEQ (EC 135) MONITORING
134,675MHZ
F) GND G)2500FT AGL


is displayed as a self-intersecting polygon - see the images in this gallery: http://imgur.com/a/Sx3i8

I assume this happens due to the order of the vertices (coordinates) in the NOTAM - I think this feature would look much nicer if there was some algorithm involved which can detect this condition and re-order the vertices Smile

Kind regards
Martin
