• Geometric locus associated with thriedra axonometric projections. Intrinsic curve associated with the ellipse generated 

      Gonzaga Vélez, Pedro Upna Orcid; Gimena Ramos, Faustino Upna Orcid; Gimena Ramos, Lázaro Upna; Goñi Garatea, Mikel Upna Orcid (Springer, 2017)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In previous work on the axonometric perspective, the authors presented some graphic constructions that allowed a single and joint invariant description of the relations between an orthogonal axonometric system, its related ...
    • Multitemporal evaluation of topographic correction algorithms using synthetic images 

      Sola Torralba, Ion Upna Orcid; Álvarez-Mozos, Jesús Upna Orcid; González de Audícana Amenábar, María Upna Orcid; Torres Escribano, José Luis Upna Orcid (SPIE, 2012)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Land cover classification and quantitative analysis of multispectral data in mountainous regions is considerably hampered by the influence of topography on the spectral response pattern. In the last years, different ...
    • Pohlke theorem: demonstration and graphical solution 

      Gimena Ramos, Faustino Upna Orcid; Gimena Ramos, Lázaro Upna; Goñi Garatea, Mikel Upna Orcid; Gonzaga Vélez, Pedro Upna Orcid (Springer, 2017)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      It is known that the axonometric defined by Pohlke, is geometrically known as a means of representing the figures of space using a cylindrical projec-tion and proportions. His theorem says that the three unit vectors ...
