The church of San Miguel de Sotosalbos in Segovia is one of the best examples of the segovian romanique. It has one unique nave with rectangular apsel, being remarkable the porch, which cornice is decorated with superb modillons and metopes. The objective was the photogrammetric survey of its four facades and roof plan at scale 1:30 with a precission of 6 mm and a pixel size below 6 mm respectively. |

Photographs of the surroundings were taken and the temporary adhesive targets location and metric references were planned. The different taking locations previously were studied with the aim of managing the later accesses. The case of the North facade is remarkable, because there was enough frontal clearance for being able to make its documentation with a certain facility, but the massive presence of trees and vegetation forced to take the photographs from an elevated positions to avoid them. The main problem to reach the necessary elevation arose from the impossibility to locate a crane or a platform in the northwest zone of the monument that could pass through the access road without damaging the neighbouring buildings and other elements, because of the road narrowness and terrain instability. |

We looked for other aerial means to provide us the necessary elevation, distances and angles for the documentation; but the presence of an inhabited nucleus, the electrical and telephone laying in the monument surroundings and the insufficient diaphanous space available to initiate the manoeuvres ruled out the possibility of using certain elements such as air balloon or helicopter. Finally we complete this facade documentation using a captive helium zeppelin. |
