Un rilievo speditivo di emergenza. Forte San José a Cartagena de Indias (Colombia)

The recent methods of survey and modeling based on digital images or laser scanner technologies, todaywidely tested, are an exceptional support for the rapidity of acquisition, especially in emergency situa-tions where it is necessary to quickly acquire a documentation in order not to stay long in a place. The Fort San Jose, designed by Juan de Herrera between 1714 and 1725 and completed by Antonio de Arévalo after almost 50 years, completes the defense of navigable access to the bay of Cartagena de In-dias between the island of Bocachica and Isla Bomba. Placed on an artificial island in front of the fort of S. Ferdinando it has undergone frequent flooding in recent years due to a sinking process. Studies relating to emergency expeditious surveys are limited and episodic, detailed in most cases in the archaeological field where urgent excavations must be carried out and phenomena and situations that can be lost must be recorded rapidly. The Italian Ministry of Heritage and Cultural Activities in 2013prepared card systems to document the damage following natural disasters. In the case of study, modern surveying methods are used, integrating the use of laser scanner technol-ogies for accessible areas and aerial photogrammetry for those facing the sea. The objective is to draw up an architectural survey that documents the state of consistency of the fortress that has never been de-tected to date and in this way initiate a monitoring of the ongoing processes. At the same time, it consti-tutes an indispensable cognitive support for possible activities and intervention strategies that aim to put an end to instability
