A new methodology to estimate the discrete-return point density on airborne lidar surveys

Balsa Barreiro, José; Lerma García, José Luis (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2014-02)

The distribution of the discrete-return point density in airborne lidar flights obtained from an oscillating mirror laser scanner is analysed and alternative formulations to determine its value are presented. The point ...
A recreational carrying capacity assessment of the 16th century Spanish Fort of Santiago on the Island of Chikly, Tunisia

Viñals Blasco, Mª José; Martínez, I.; Abdennadher, A.; Teruel Serrano, Mª Dolores (WIT Press, 2014)

The increase in cultural tourism has revealed the vulnerability of the heritage resources during the phase of tourism exploitation and, thus, the need to set limits and to establish visitor management tools to ensure the ...
A review and analyses of plumb-line calibration

Lerma García, José Luis; Cabrelles López, Miriam (Wiley: 12 months, 2007)

[EN] Radial and decentring distortion parameters have long been reported as fundamental elements in camera calibration, especially in digital close range photogrammetry. This paper reports on an investigation for the ...
A robust and hierarchical approach for the automatic co-registration of intensity and visible images
