CALCULO DE AZIMUTES E RUMOSPara os cálculos de azimutes : N Az = arc cosse ( N/D1-2) 2 Onde : = N,2- N,1 Az1-2 N D1-2 = Distancia de 1 e 2 1 E E
Neste caso a distancia de DeltaN e D1-2 deu-se através do Programa Autocad conforme figura 1. Arc cós(6.54/8.42) => Az 1-2 =39°2´18.87”
Rumos de 1-2= Az 1-2
Rumos1-2=39°2´18.87”NE
Para os demais pontos :
Utiliza-se a formula Azi,i+1= Azi-1,i+ângulo externo de i -180
Az2-3= 39°2´18.87”+266°46´12”-180° =>-------------------- Az2=125°48´30.8”
Az3-4= 125°48´30.8”+106°49’48”-180°=>--------------------Az3= 52°38’18.87”

Az6-7=140°58’42.8”+167°43’12”-180°=>---------------------Az6=128°41’54.8”
Az7-8=128°41’54.8”+269°15’36”-180°=>---------------------Az7=217°57’30.8”
Az8-9=217°57’30.8”+269°04’48”-180°=>---------------------Az8=307°02’18.8”
