LOPEZ BLANCO, Jorge; VALDEZ MUCINO, Ivonne  e  UGALDE RIVERA, Jesús. Corrección fotogramétrica de segmentos digitizados de fotografías aéreas aplicando un SIG, para la determinación del uso del suelo en la sierra de Quetzaltepec, México. Invest. Geog [online]. 1996, n.33, pp.9-30. ISSN 2448-7279.

The application of a photogrammetric method, in a GIS environment, to correct the position of segment's coordinates digitized on near vertical aerial photos, is presented. The distortions corrected with the method are caused by relief displacement and central projection. The photo exposure station was determined according to coordinates (X₀,Y₀,Z₀) and rotation angles (w,φ,k). The results of processing 16 aerial photographies led us to generate a map of land use units for 1989. The total root mean square error per photo goes from 14.6 to 40.2 m. The information was proccessed in a GIS installed in a personal computer.
