The historic built environment is the quintessential embodiment of diachronicity and cultural continuum of societies through time. This richness is inscribed in materiality of heritage assets in the form of stratification that appears as constructive patchwork, bearing the implicit and explicit traces of historical evolution, intelligible through their configuration. Mainly intended for archaeological excavation work, Harris' method, which is based on a set of inherent principles and rules, is consensually adopted for the study of architectural stratification. In this article, we aim to approach buildings stratification from non-destructive perspective in their spatio-morphological and temporal multidimensionality, by proposing an ad-hoc integrated workflow for architectural assets. We first propose a conceptual model, conceiving historical edifices in terms of nested physical and chronological entities. Then, we present an interactive information management system for the integration and multimodal visualization of stratigraphic data, and the analyses performed within the same workspace. Besides the possibility of managing simultaneously geometrical and non-geometrical data, this approach provides both relative and quantified chronology visualization, for an integral understanding of buildings morphogenesis. On a practical level, the system shows to improve insight by providing a retrospection on different morphological past states of buildings, which support reconstitution tasks and conservation planning.

Purpose This paper aims to suggest feasible solutions to overcome the problem of unmanned aerial vehicles integration within the existing airspace. design/methodology/approach It envisages innovative time-based separation procedures that will enhance the integration in the future air traffic management (ATM) system of next generation of large remotely piloted aircraft system (RPAS). 4d navigation anddynamic mobile area concepts, both proposed in the framework of Single European Sky ATM Research program, are brought together to hypothesize innovative time-based separation procedures aiming at promoting integration of RPAS in the future ATM system. Findings Benefits of proposed procedures, mainly evaluated in terms of volume reduction of segregated airspace, are quantitatively analyzed on the basis of realistic operational scenarios focusing on monitoring activities in both nominal and emergency conditions. Eventually, the major limits of time-based separation for RPAS are investigated. Practical implications The implementation of the envisaged procedures will be a key enabler in RPAS integration in future ATM integration. Originality/value In the current ATM scenario, separation of RPAS from air traffic is ensured by segregating a large amount of airspace areas with fixeddimensions, dramatically limiting the activities of these vehicles.

4Record is a tool for creating and. controlling spatiotemporal (4d) paths in a Virtual Environment (VE). It has been originally developed as a component of an application that uses 4d CAd models of buildings (with time as 4(th) dimension showing the building process progression) for the interactive visualization of construction processes. However its plug-in like design allows the integration in different applications. 4Record allows recording and replaying user navigation through space and trough building process time, removing and re-recording these paths at any desired point (in space and time), and to save or load them. We separated main 3d interaction in the VE from path recording and traveling through the building process time of the 4d model anddeveloped one input device for each task. Using a dedicated input device similar to mobile devices like mp3 players or voice recorders as physical control for time travel and path recording, we want novice users to become quickly familiar with 4Record and to achieve a high ease of use of the whole interface.
