Central to the entire discipline of heritage restoration and conservation is the concept of information management. Nevertheless, traditionally, conservation and restoration has been a poorly documented discipline, which has led not only to a lack of standardization and awareness about the processes carried out in the past, but also poses problems both when new restoration works are necessary and for the preventive conservation of the elements of heritage. This study sets out to propose a conceptual framework to explore the relationship between conservation of heritage and information management on the basis of case studies; in particular: a spatial data infrastructure (SDI) of a regional government concerning an endangered plant (wild grapevine) with an important potential for cultural and touristic uses in a wine-making region; an open data guide—the Digital Guide of Andalusian Cultural Heritage; a university repository connected to Europeana, which contains reports and outcomes of projects of geometric documentation of elements of heritage; a repository of an organization in charge of the protection and care of the heritage; and finally, two examples of the use of heritage building information models (HBIM) in complex monuments. After discussing the characteristics of each case, this paper concludes that, although the availability of information and tools is growing, further progress is still necessary concerning the interoperability, outreach and reuse of the different solutions.

For decades, human activities have gradually destroyed the natural habitats of wild grapevine, Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi, and nowadays this species is endangered in southern Europe. In this paper, 94 populations of this species have been localized and characterized in the Andalusian region in the Iberian Peninsula between 1989 and 2013. Location, ecological aspects, and sanitary characteristics are described. Must properties and in vitro tolerance to calcareous conditions were also checked. The paper also contains a global description of female and male individuals. Two hundred individuals from six river basin populations have been sampled, and their genetic structure analyzed by using 25 nuclear microsatellites loci to investigate the gene diversity of wild grape populations in Andalusia at two levels: total individuals and at river basin populations. Also, the genetic relationship of wild and cultivated accessions has been tested. Wild grapevine is considered the ancestor of the cultivated varieties and should be preserved as this material could be used to start breeding programs of cultivated varieties and also to restore riverbank forests, which constitute one of the worst preserved ecosystems in the area.

Keywords: 3D modelling, Old photographs, Film negatives, Structure from Motion (SfM), Perspective geometry, Monoscopic methods in photogrammetry Three-dimensional models with photographic textures have become a usual product for the study and dissemination of elements of heritage. The interest for cultural heritage also includes evolution along time; therefore, apart from the 3D models of the current state, it is interesting to be able to generate models representing how they were in the past. To that end, it is necessary to resort to archive information corresponding to the moments that we want to visualize. This text analyses the possibilities of generating 3D models of surfaces with photographic textures from old collections of analog negatives coming from works of terrestrial stereoscopic photogrammetry of historic buildings. The case studies presented refer to the geometric documentation of a small hermitage (done in 1996) and two sections of a wall (year 2000). The procedure starts with the digitization of the film negatives and the processing of the images generated, after which a combination of different methods for 3D reconstruction and texture wrapping are applied: techniques working simultaneously with several images (such as the algorithms of Structure from Motion – SfM) and single image techniques (such as the reconstruction based on vanishing points). Then, the features of the obtained models are described according to the geometric accuracy, completeness and aesthetic quality. In this way, it is possible to establish the real applicability of the models in order to be useful for the aforementioned historical studies and dissemination purposes. The text also wants to draw attention to the importance of preserving the documentary heritage available in the collections of negatives in archival custody and to the increasing difficulty of using them due to: (1) problems of access and physical conservation, (2) obsolescence of the equipment for scanning and stereoplotting and (3) the fact that the software for processing digitized photographs is discontinued.

The concept of mock-up, which share with the drawing the expressive synthesis for the analysis of the architectural form and evolution, is an invaluable asset for the preservation of the heritage. To mark the 175th anniversary of the Práxedes Mateo Sagasta’s secondary school of Logroño (Spain), an exhibition about the history of the institution was organized at the premises of La Rioja Library. The current school building became operational in 1900 and was built on the former site of a Carmelite convent. In fact, the convent rooms were the first location for the school, after the expropriations of religious communities during the mid-19th century. For the benefit of the aforementioned exhibition, it was considered interesting to generate a three-dimensional (3D) virtual reconstruction of the convent buildings to show how it would have looked. However, the lack of sufficient contemporary graphic information was a challenge, so it was decided that an efficient solution would be to generate the virtual reconstruction from a paper craft model, which had been created by the librarian of the secondary school as a result of his research on this matter. This text describes the 3D modelling of that cut-out element by means of monoscopic photogrammetry (perspective drawing) and the use of non-realistic rendering based on the appearance of the paper mock-up (and not trying to recreate the real image of the buildings) so as to provide a suggestive view of the convent and create interactive exhibition items. Moreover, the text deals with the long-term preservation and the improvement of the re-use of the 3D models. The former by resorting to institutional repositories —from which users can download the full detailed versions— and the latter employing versions able to be visualized in 3D warehouses (such as Sketchfab) and augmented reality (AR) applications.Highlights:A significant part of the architectural heritage is represented by mock-ups of different materials (paper, wood, metal and so on).Virtual modelling and augmented reality (AR) can be appropriate tools for materializing, recovering and disseminating scale models to the public.Techniques for geometric documentation and visual representation need to be adapted in order to tackle the peculiar features of these elements (size, materials, fragility, etc.).
