Integración de sensores aéreos y terrestres para la producción de cartografía multiescala 3D en la Alhambra y su territorio.

Abstract

The production of new digital cartography and ortophotos for the monuments of the Alhambra and Generalife is part of the SIALH project, which aims for the development of the Information System of the Alhambra. Map production in the area of the Alhambra is a challenge due to various factors such as the heritage value of the elements to be represented, the complex topography of the territory under study and the requirements of precision and detail exceeding the usual standards in cartography. The need for a multiscale cartography which must support both local-scale projects (up to 1:5000) and detailed planimetric surveys also
constitutes a challenge. The methodology employed combines aerial (LiDAR, digital photogrammetry) and ground sensors (laser scanning) to ensure maximum precision while emphasizing the role of data model as a key element for ensuring the multi-scale information and its usability in projects of very different scales.
