Le géoréférencement. Dans la plupart des projets SIG [système d'information géographique], on procède tout d'abord à un découpage géographique de l'espace, qui délimite la zone d'étude. La première étape est de géoréférencer cet espace, c'est-à-dire le délimiter précisément par des coordonnées cartographiques (ou géographiques). C'est cette conformité qui permettra de superposer des plans de diverses natures. Pour assurer cette superposition, les différentes couches d'informations géographiques doivent avoir le même système de projection.  3, record 1, French, - g%C3%A9or%C3%A9f%C3%A9rencement

¿Cómo es el registro de una imagen? En primer lugar, debemos saber cómo registrar una imagen en otra. En este caso contamos con una imagen principal (Master), es decir, la parte escaneada de un mapa, y una imagen secundaria (Slave). Para empezar, leemos las coordenadas (números de fila y columna) de algunos puntos destacados de la imagen principal y las buscamos en la imagen secundaria. A continuación pedimos al programa que ejecute la transformación del contenido de la imagen completa. Después de este proceso se pueden superponer las dos imágenes.  1, record 2, Spanish, - registro%20de%20la%20imagen

Modifying the geometry of an image (which may be from either a remotely sensed or map data source) [that] usually involves rectification and/or registration.  3, record 3, English, - resampling

Record number: 3, Textual support number: 1 CONT

Overview of resampling methods. From the perspective of space, a satellite camera or sensor takes images that provide unique Earth information at scales ranging from very small to very large. To better understand an image, its shape, scale and perspective often are changed by rectification, orthorectification or map projection to relate it to real world coordinates. During that process, however, gaps between pixels may form, requiring that images be resampled to fill in those missing pixels. There are basically 3 methods of resampling : nearest neighbor, bilinear interpolation and cubic convolution.  4, record 3, English, - resampling

Depending upon the relation between the DEM [Digital Elevation Model] and radar resolutions, the interpolation method used to resample from map to radar image geometry can become important.
