[EN] Since ancient times, human beings have been interested in knowing their environment in order to make the right decisions in territorial management. The spatial component is a feature of great importance in the assets ...
Accuracy analysis of a mobile mapping system for close range photogrammetric projects

Navarro Tarin, Santiago; Lerma García, José Luis (Elsevier, 2016-11)

[EN] Image-based mapping solutions require accurate exterior orientation parameters independently of the cameras used for a survey. This paper analyses the inclusion of up to two stereo-based geometric constraints in the ...
Actualización de cartografía catastral urbana mediante LiDAR y SIG

Sánchez Lopera, José; Lerma García, José Luis (Grupo de Tecnologías de la Información Geográfica, Asociación de Geógrafos Españoles, 2012-03)

[EN] This paper presents a methodology to automatically update urban cartography using LiDAR (Light Detección And Ranging) data and GIS (Geographic Information Systems). It is worth having access to large scale urban ...
Airborne light detection and ranging (LiDAR) point density analysis

Balsa Barreiro, José; Avariento Vicent, Joan Pere; Lerma García, José Luis (Academic Journals, 2012-08)

The point density is a preeminent parameter on airborne laser scanner surveys. It is not only related to accuracy but costs and savings. The lack of uniformity of the point density across the survey is well-known in ...
Analysis and Development of Augmented Reality Applications for the Dissemination of Cultural Heritage

Blanco Pons, Silvia (Universitat Politècnica de València, 2021-12-27)

[ES] La RA consiste en la superposición de elementos virtuales sobre el entorno real, de manera que el usuario percibe estos elementos como si formaran parte de la realidad que está visualizando. Las aplicaciones de RA en ...
Analysis of repeatability on videogrammetry for infants' cranial deformation
