Puede que ya te hayas dado cuenta de que en la ventana de CloudCompare estamos en una caja 3D que se parece a nuestro mundo real pero que tiene sus propias referencias. A diferencia de un SIG, que determinar\u00e1 si dos puntos en dos capas diferentes est\u00e1n en el mismo lugar comparando sus coordenadas XY, en CloudCompare esto se har\u00e1 calculando la distancia en las referencias 3D internas. Cuando quiera asignar un valor RGB a un punto de la nube de puntos, buscar\u00e1 el p\u00edxel m\u00e1s cercano en la imagen. Pero como estamos en un mundo 3D, este p\u00edxel no es necesariamente el que tiene la misma XY, sino el que tiene la menor distancia XYZ. En un terreno irregular, esto puede ser muy diferente del resultado que obtendr\u00edamos con un SIG.<\/p>\n\n\n\n<p>Cuando cargamos la nube de puntos (v\u00e9ase la imagen de arriba), los valores Z eran de unos 589 metros. Nuestra ortofoto no tiene coordenadas Z, es decir, tiene valores Z =0. Si dejamos el desfase Z tal y como est\u00e1 (con valor 0) podemos estar seguros de que los puntos m\u00e1s cercanos no corresponder\u00e1n a las coordenadas XY correctas. Vamos a desplazar los p\u00edxeles de la imagen 589 metros.
