Such a road ranged between Mexico City and Santa Fe, New Mexico, USA. Some remnants still survive in Mexico, but their geographic location, position, length and condition are not well known. By means of fieldwork and a search of historic records left by the Spaniards, three segments of the Royal Road were identified. Three high-resolution multispectral images from the Pleiades satellite were acquired. Such images cover three zones where the Royal Road segments were located, and fieldwork was carried out. Due to degradation, the segments of the Royal Road show a low contrast with respect to the surroundings but a distinctive texture. A procedure of enhancement and sharpening was applied to the images based on the Vector Laplacian operator and Principal Component Analysis (PCA). Such a procedure enhances the texture and the edges of the Royal Road segments. An RGB false color composite formed by the Laplacian operator, the first principal component, and band 4, produced an image where the Royal Road segments are clearly observed. By means of fieldwork, the geographic coordinates and condition of the Royal Road segments were identified.]]></p></abstract>

Tal camino corría entre la Ciudad de México y Santa Fe, en Nuevo México, USA. Algunos remanentes aun sobreviven en México, pero su localización, longitud y condición no son bien conocidas. Por medio de trabajo de campo y de una investigación de los registros dejados por los españoles, se identificaron tres segmentos del Camino Real. Se adquirieron tres imágenes multiespectrales de alta resolución del satélite Pleiades. Tales imágenes cubren tres zonas donde fueron identificados los segmentos del Camino Real y se llevó a cabo un trabajo de campo. Debido a la degradación, los segmentos del Camino Real muestran bajo contraste con respecto al entorno pero una textura distintiva. Se aplicó un procedimiento de realce y agudizamiento a las imágenes con base al operador Vectorial Laplaciano y al análisis de componentes principales (ACP). Tal procedimiento realza la textura y los bordes de los segmentos del Camino Real. Un compuesto RGB falso color formado por el operador Laplaciano, la primera componente principal y la banda 4, produjo una imagen donde los segmentos del Camino Real son claramente observados. Por medio de trabajo de campo se identificaron las coordenadas y las condiciones de los segmentos del Camino Real.]]></p></abstract>
