A demonstração de rota permite especificar uma origem e um destino como um par de coordenadas de latitude/longitude ou como um ID de lugar. Para copiar as coordenadas de latitude/longitude, encontre e clique em um local no mapa e cole no formulário.
Depois de selecionar Receber trajeto, a demonstração vai mostrar a resposta do método computeRoutes como um trajeto no mapa.
Confira o código-fonte de exemplo completo
A demonstração a seguir permite testar a criação de vários tipos de rotas. Clique no mapa para copiar as coordenadas de latitude/longitude de um local. Cole as coordenadas no formulário para receber rotas.
