LOPEZ BLANCO, Jorge  e  ARIAS CHALICO, Teresita. Elaboración de videomapas mediante la corrección fotogramétrica de imágenes de video en color: La región de La Montaña de Guerrero. Invest. Geog [online]. 1998, n.37, pp.21-35. ISSN 2448-7279.

A photogrammetric method to correct the position of pixels coordinates on near vertical axis video imagery was applied. Distortions corrected with that method are caused by relief displacement and photographic projection and it is carried out by means of a photogrammetric resection procedure. A digital terrain model with a 4 m pixel-size was performed In order to determine the photogrammetric correction. Video imagery processed allowed us to produce a corrected videomosaic that include an area of almost 20 square kilometers. The total root mean square error in the photogrammetric resection procedure per image goes from 6 to 25 m. The results of processing these images will allow us to produce a map of land use/land cover units.
