Such imagery represent a unique data source, which combined with photo interpretation and reality-based 3D reconstruction techniques, can offer a more complete modelling procedure because it adds the fourth dimension of time to 3D geometrical representation and thus, allows urban planners, historians, and others to identify, describe, and analyse changes in individual scenes and buildings as well as across landscapes. Particularly important to this approach are historical aerial photos, which provide data about the past that can be collected, processed, and then integrated as a database. The proposed methodology employs both historical (1945) and more recent (1973 and 2000s) aerial images from the Trentino region in North eastern Italy in order to create a multi-temporal database of information to assist researchers in many disciplines such as topographic mapping, geology, geography, architecture, and archaeology as they work to reconstruct building phases and to understand landscape transformations (Fig. 1). year: 1945 year: 1973 year: 2005 Figure 1: Examples of multi-temporal aerial imagery used in the project to acquire spatio-temporal data and identify anthropomorphic changes landscapes. 1. INTRODUCTION Since the advent of photography in the XIX century, the possibility of acquiring images from the air has been recognised as an invaluable source of data, especially for military strategic planning. Prior to satellite imagery, aerial photographs were the primary source of information about the Earth’s surface. Images from balloons, airplanes, helicopters, and even modern unmanned drones, are important sources of information for mapping purposes; however, these images offer many other potential uses that are typically not investigated once the map is produced. In particular, historical aerial imagery are often overlooked despite the fact that they store unique information about the past, that is useful for many disciplines including topographic mapping, geology, geography, architecture and archaeology. In the era of digital photogrammetry, historical photos represent a unique resource that, together with photo interpretation and reality-based 3D reconstruction techniques, can offer a more complete modelling procedure, by adding the fourth dimension of time to 3D geometrical representations. A spatio-temporal or 4D modelling approach allows researchers to identify, describe, and subsequently analyse changes in individual scenes and buildings as well as across landscapes. Such data about change through time assist researchers as they work to reconstruct changes in buildings and understand landscape transformations. For example, researchers have used multi-temporal imagery for many purposes like: (1) investigation of land cover dynamics (Ratcliffe & Henebry, 2004; Sandric et al., 2007), (2) detection of change detection in historic city centers (Patias et al., 2011), (3) creation of 4D interactive presentations of heritage sites (El-Hakim et al., 2008), (4) modelling of architectural changes (Stefani et al., 2011), (5) 4D city modelling (Schindler, 2010) and (6) urban analyses (Vizzari, 2011). The article presents a spatio-temporal modelling approach using the Trentino region (Italy) as a case study. The employed methodology makes use of both historical and more recent aerial images and orthophotos (Fig. 1) in order to acquire data to create a multi-temporal database of information. Rigorous photogrammetric measurement techniques for image triangulation, Digital Surface Model (DSM) production and orthoimage generation were applied to historical photos dating back to the Second World War (WWII) in order to derive metric and geo-referenced information about past scenes.
