Representação dos waypoints obtidos.
A vermelho a localização do veículo e os pontos pretos são os waypoints.
Para complementar a intrepertação. (A linha reta une o início da rota e o destino)
Outros exemplos que mostram que nem todos os waypoints estão corretos.
Calcular distâncias entre a posição do veículo e os waypoints.
Verificação dos pontos de início e fim de cada etapa e sua instrução.
Criação de uma metodologia para fecho dos waypoints.
