INTERPRETACION DE RESULTADOS: Es por ello que lo que obtenemos es negativo en latitud y longitud porque estamos en la parte sur y oeste con respecto al meridiano y ecuador : -12.220334,-76.927418 RELACION DE ANGULOS DE LATITUD – LONGITUD Y DISTANCIAS EN LA SUPERFICIE TERRESTRE. 1)Para que se produzca un desplazamiento de 1m hacia una dirección única(longitud o latitud) , se calculara cuando tendrá que variar el ángulo: Se asumirá como un sector circular: ° 2) La mínima detección de distancia: R=6367500;%Radio prom de la tierra en m d=angulo*pi*R/180 = 0.1852 m=18.52cm
