Anomaly Detection Using Remote Sensing for the Archaeological Heritage Registration

The aim of this work is an approach using multisensor remote sensing techniques to recognize the potential remains and recreate the original landscape of three archaeological sites. We investigate the spectral characteristics of the reflectance parameter and emissivity in the pattern recognition of archaeological materials in several hyperspectral scenes of the prehispanic site in Palmar Sur (Costa Rica), the Jarama Valley site and the celtiberian city of Segeda in Spain. Spectral ranges of the visible-near infrared (VNIR), shortwave infrared (SWIR) and thermal infrared (TIR) from hyperspectral data cubes of HyMAP, AHS, MASTER and ATM have been used. Several experiments on natural scenarios of Costa Rica and Spain of different complexity, have been designed. Spectral patterns and thermal anomalies have been calculated as evidences of buried remains and change detection. First results, land cover change analyses and their consequences in the digital heritage registration are discussed.

A data model for Cultural Heritage within INSPIRE.

Esta monografía presenta los fundamentos, contexto y detalles técnicos de un Esquema de Aplicación para la incorporación de datos espaciales relativos al patrimonio cultural en el marco definido por la directiva europea INSPIRE sobre información geográfica. Abstract: This monograph presents the background, context and technical details of an Application Schema for the inclusion of cultural heritage spatial data into the INSPIRE framework. Nowadays, INSPIRE provides the most relevant framework for the dissemination and exchange of geographical data, covering many different thematic fields, particularly relevant for envi-ronmental datasets. Although cultural heritage elements are partially addressed within INSPIRE, there is no specific documentation on how these data should be considered, structured and published. This text aims to provide technical guidelines for decision makers, public administrations and the scientific community for the definition and implementation of harmonized datasets for cultural heritage, according to the interoperability principles of INSPIRE.

The historical heritage of domestic architecture is a reliable model for a satisfactory design. The case of the Mediterranean region

The purpose of this paper is to expose the importance of observing cultural systems present in a territory as a reference for the design of urban infrastructures in the new cities and regions of rapid development. If we accept the idea that architecture is an instrument or cultural system developed by man to act as an intermediary to the environment, it is necessary to understand the elemental interaction between man and his environment to meet a satisfactory design. To illustrate this purpose, we present the case of the Eurasian Mediterranean region, where the architectural culture acts as a cultural system of adaptation to the environment and it is formed by an ancient process of selection. From simple observation of architectural types, construction systems and environmental mechanisms treasured in mediterranean historical heritage we can extract crucial information about this elemental interaction. Mediterranean architectural culture has environmental mechanisms responding to the needs of basics habitability, ethnics and passive conditioning. These mechanisms can be basis of an innovative design without compromising the diversity and lifestyles of human groups in the region. The main fundament of our investigation is the determination of the historical heritage of domestic architecture as holder of the formation process of these mechanisms. The result allows us to affirm that the successful introduction of new urban infrastructures in an area need a reliable reference and it must be a cultural system that entailing in essence the environmental conditioning of human existence. The urban infrastructures must be sustainable, understood and accepted by the inhabitants. The last condition is more important when the urban infrastructures are implemented in areas that are developing rapidly or when there is no architectural culture.

Using cloud technologies for engaging people with cultural heritage

Cultural heritage is an important asset of Europe which is largely underexplored. One of the main reasons is that the general public do not really incorporate cultural activities in their life style. Currently, curators and professionals in the heritage sector face the toughest challenges on how to attract, engage and retain visitors of heritage institutions (libraries, museums, archives and historical societies). TAG CLOUD FP7 European project seeks to overcome this situation and promote lifelong engagement with culture by personalising the visitors? cultural experiences through cloud technologies.

Acústica de las iglesias jesuíticas como parte del patrimonio integral en Córdoba y San Ignacio Miní

En esta investigación se aborda el tema del comportamiento acústico de las Iglesias Jesuíticas de la ciudad de Córdoba (Argentina) y San Ignacio Mini ubicada en la localidad de San Ignacio, provincia de Misiones (Argentina), construidas hace dos siglos atrás y declaradas Patrimonio de la Humanidad, con el objetivo de evaluar los parámetros que determinan la comprensión de la palabra y la aptitud de cada una de las iglesias para el canto y la música religiosa. En una primera etapa la investigación se orientó a profundizar en las características constructivas interiores de cada templo y a proponer una metodología de análisis para comparar los resultados de las mediciones objetivas, realizadas mediante la implementación de mediciones in situ, con los resultados de las apreciaciones subjetivas resultantes de la elaboración de encuestas, a los fines de caracterizar acústicamente cada espacio sonoro. Se seleccionaron, para la caracterización objetiva de cada templo, aquellos parámetros que permiten sintetizar las propiedades acústicas relacionadas con la música y la palabra, y aquellos que posibilitan medir la proporción efectiva de las primeras reflexiones, consideradas como índices subjetivos de la capacidad de distinción del sonido por parte del oyente. Se comparan los valores alcanzados con las preferencias subjetivas obtenidas en las encuestas de opinión. Se relevaron tiempos de reverberación altos en todas iglesias, fuera de los considerados óptimos para cada recinto. Se analizaron los índices de calidad y se comprobó cómo influyen los diferentes materiales en el comportamiento acústico de cada recinto. Para la evaluación subjetiva se implementó una encuesta ya validada en la que se privilegió la fácil asociación entre parámetros acústicos y psicoacústicos, esto posibilitó encontrar aquellos parámetros objetivos, simulados con público, que estuviesen fuertemente relacionados con el juicio subjetivo, así como aquellos con menor correlación. La búsqueda y relevamiento de material grafico, fotográfico y otros documentos históricos posibilitó la reconstrucción de cada iglesia para su modelización y la evaluación del comportamiento de todos los templos con la presencia de feligreses, no habiéndose podido realizar mediciones bajo esta condición. El interés por obtener datos acústicos más precisos de la Iglesia San Ignacio Mini, que actualmente se encuentra en ruinas, llevó a utilizar herramientas más poderosas de cálculo como el método de las fuentes de imagen “Ray Tracing Impact” por medio del cual se logró la auralización. Para ello se trabajó con un archivo de audio que representó la voz masculina de un sacerdote en el idioma jesuítico-guaraní, recuperando así el patrimonio cultural intangible. ABSTRACT This research addresses the acoustic behavior of the Jesuit Churches in Cordoba City (Argentina) and San Ignacio Mini (located in the town of San Ignacio, Misiones, Argentina), built two centuries ago and declared World Heritage Sites, with the objective to evaluate the parameters that determine the speech comprehension and the ability of each of the churches for singing of religious music. The first step of the work was aimed to further investigate the internal structural characteristics of each temple and to propose an analysis methodology to compare the objective results of in situ measurements with the subjective results of surveys, in order to characterize acoustically each sound-space. For the subjective characterization of each temple, those parameters that allow synthesizing the acoustic properties related to music & speech and measuring the subjective indices for the recognition of sounds, were selected. Also, the values were compared with the ones obtained from the surveys. High reverberation times were found in all churches, which is not considered optimal for the enclosed areas of the temples. The quality indices were analyzed and it was found how the different materials influence in the acoustic behavior of each enclosure. For subjective evaluation, a survey was implemented (that was previously validated) where the association between acoustic and psychoacoustic parameters was privileged; this allowed to find those objective parameters who were strongly related to the subjective ones, as well as those with lower correlation. Photographic and graphic material and other historical documents allowed the reconstruction of each church for its modeling, and also the evaluation of the performance of all the temples in the presence of their congregation. The interest in obtaining more accurate acoustic data of the San Ignacio Mini Church, which is now in ruins, led to the use of most powerful methods, as for example the image-sources "Ray Tracing Impact" method. For this, an audio archive was used, representing a male voice of a priest in the Jesuit-Guaraní language; recovering in this way intangible cultural heritage.

Toynbee and the global comprehension of the historical heritage

Toynbee entendió que la historia es algo que sucede a personas como nosotros y de nuestro mismo mundo. Así toda la historia y todos aquellos restos que hemos recibido del pasado deben ser la base sobre la que reconstruir una relación más honesta entre nosotros, nuestras necesidades y nuestras mejores aspiraciones. Esta es la idea principal sobre la que gira la comprensión global de nuestra responsabilidad en la preservación de nuestra herencia natural y cultural. En cualquier lugar son abandonadas piezas históricas sin uso sin concederles un sentido. Redescubrir el nexo entre diferentes objetos arquitectónicos y poner de manifiesto para la gente común que sentido quieren transmitirnos es una de las más importantes e interesantes pro-puestas para explicar nuestra historia.

Los árboles singulares en el paisaje. Propuesta de un modelo para su evaluación: el caso del territorio histórico de Álava

La Tesis Doctoral que se presenta trata de profundizar en el conocimiento del patrimonio arbóreo, en la cuestión de la evaluación y la singularidad a nivel de ejemplares y agrupaciones. La metodología incorpora nuevas herramientas, modelos y criterios utilizados en la valoración del paisaje y de los recursos naturales. Siendo el árbol un generador de espacio y habitats, solo o en masa, es vínculo entre la naturaleza y el ser humano, las comunidades y sus costumbres. Desde estos parámetros se indagan los procesos que permiten estimar el significado, la importancia y el valor del árbol para llevarlo a una consideración de Singular y/o Monumental. El estudio se basa en los sistemas de catalogación, tras el reconocimiento, localization y selección de ejemplares. Así mismo, se explora la relación sistémica entre árbol y entorno para poner de relieve la importancia del árbol en la configuración de determinados paisajes culturales y ecológicos -como son los robledales de antiguos trasmochos en Euskadi-. Sobre un primer inventario se realiza un estudio pormenorizado de cada árbol registrado y, en un procedimiento paramétrico, se definen criterios -ecológicos y paisajísticos, etnográficos y culturales- de selección de elementos y de evaluación. La obtención de distintos índices de singularidad para los árboles, utilizando modelos tanto cualitativos como cuantitativos, sirve como vía hacia una categorization de los árboles muestreados. A partir de la figura de "Árbol Singular", recogida en la Ley 16/ 1994, de Conservación de la Naturaleza del País Vasco se realiza una revisión del marco legislativo y el régimen de protección, haciendo un análisis a nivel local, autonómico y estatal. Dicho examen pone de manifiesto la diversidad de contextos y significados bajo los que se presentan los árboles. Se muestra también una (in)definición: cierta ambigüedad en torno a la definición que induce a diferentes interpretaciones y nomenclaturas en un intento de delimitar la categoría para regularlo jurídicamente. Estas figuras concebidas desde las políticas de protección ambiental, no siempre resultan del todo efectivas. El Catálogo de Árboles Singulares del País Vasco, creado por Decreto como instrumento para poner en valor estos recursos naturales, no ha sido actualizado desde hace casi veinte años. Sin embargo, se han llevado a cabo iniciativas de ampliación como el trabajo impulsado por el Departamento de Medio Ambiente y Biodiversidad de la Diputación Foral de Álava para el inventario de los árboles singulares del Territorio Histórico de Álava y la propuesta de catálogo a partir del cual se desarrolla esta Tesis Doctoral. Desde estas reflexiones y el desarrollo de modelos para la evaluación y catalogación de los ejemplares registrados, la investigación trata de descifrar cómo observamos a los árboles con los que nos vinculamos, cómo son identificados, a través de qué otros parámetros intangibles les damos valor, y por qué necesitamos clasificarlos. El trabajo concluye con propuestas y acciones alternativas para la conservación y mejora de los árboles que se proponen como singulares, entre ellas, la divulgación y la sensibilización para garantizar el compromiso y la ampliación en el futuro de un catálogo abierto para los árboles de interés. ABSTRACT The PhD thesis here presented tries to deepen the knowledge of tree heritage, the issue of evaluation and singularity where it comes to either specimen or groups. The methodology includes new tools, models and criteria to be used in the assessment of landscape and natural resources. With the tree being a creator of space and habitats, alone or in groups, it is a link between nature and humans, societies and their habits. Using these parameters processes are being sought after: processes that allow us to assess the meaning, the importance and the value of trees in order to lead us to considering a tree as being a 'Singular tree' and/or 'Heritage tree'. The research is based on cataloging systems, after recognizing, localizing and selecting of specimen. This way, the systemic relation between the tree and its surrounding is being explored to get a view on the importance of trees in certain cultural and ecological landscapes -such as the oak fields consisting of ancient pollards in the Basque Country-. After a first inventory a detailed study is performed of each registered tree and, using a parametric method, criteria for selection of elements and evaluation are defined -ecological and those concerning the landscape, as well as ethnographical and cultural-. The creation of different indexes of singularity for trees, using qualitative as well as quantitative models, serves as a way to categorize the selected trees. A revision is done on legislation and the protection regimen, analyzing on a local, autonomic state and national level, parting from the concept of the Singular Tree, as included in the Law 16/1994, of Nature Conservation of Basque Coutry. This review proves the diversity of contexts and meanings in which the trees are being presented. Also an (un)definition appears; certain ambiguity of the definition which induces different interpretations and nomenclatures in an attempt to limit categorization in order to legally regulate. These concepts created out of environment protection politics do not always turn out to be completely effective. The Catalogue of Singular Trees in the Basque Country, created by decree as an instrument to value these natural resources, has not been updated since almost twenty years. However, there have been initiatives of amplification such as the work promoted by the Environment and Biodiversity Service of Provincial Council of Alava to create the inventory of singular trees of the Historical Territory of Álava and the catalogue proposal which forms the starting point of this PhD thesis. Parting from these considerations and the development of models for evaluation and cataloging of the registered specimen, the investigation attempts to unravel the way we observe the trees with which we link, how they are identified, by which intangible parameters we assess them and why we need to classify them. This study ends with proposals and alternative actions for the conservation and improvement of the trees that are being proposed as being singular. Among them are the publication and creating of awareness to guarantee the commitment and the development of an open catalogue for significant trees.

Maragogipinho - as vozes do barro: práxis educativa em culturas populares

Este trabalho apresenta uma observação acurada do universo da cerâmica no povoado de Maragogipinho, Bahia. A pesquisa revela quem são os mestres e mestras do barro, dá a conhecer o seu processo criativo e educativo. Esses homens e mulheres são protagonistas do patrimônio cultural imaterial brasileiro, eles detêm e socializam conhecimentos que perpassam gerações, saberes tecidos em práticas de ensino não sistematizadas e nem legitimadas pelas culturas hegemônicas. A educação artesanal está fundada na ancestralidade, na repetição e na invenção, no constante diálogo entre a tradição e a emergência da modernidade: novas formas de criação e antigos segredos de ofício se misturam, numa tensão permanente entre transformação e conservação. O artesão e a artesã vivem o seu legado cultural e o mantêm vivo, reinventando-o e atualizando-o eternamente. Essa herança conserva a conexão com o passado, mas se reveste de novos símbolos e significados no presente para fortalecer a identidade dos autores e de suas comunidades, e para dar sentido ao futuro.

On Modeling an Innovative Monitoring Network for Protecting and Managing Cultural Heritage from Risk Events

In this paper the model of an Innovative Monitoring Network involving properly connected nodes to develop an Information and Communication Technology (ICT) solution for preventive maintenance of historical centres from early warnings is proposed. It is well known that the protection of historical centres generally goes from a large-scale monitoring to a local one and it could be supported by a unique ICT solution. More in detail, the models of a virtually organized monitoring system could enable the implementation of automated analyses by presenting various alert levels. An adequate ICT solution tool would allow to define a monitoring network for a shared processing of data and results. Thus, a possible retrofit solution could be planned for pilot cases shared among the nodes of the network on the basis of a suitable procedure utilizing a retrofit catalogue. The final objective would consist in providing a model of an innovative tool to identify hazards, damages and possible retrofit solutions for historical centres, assuring an easy early warning support for stakeholders. The action could proactively target the needs and requirements of users, such as decision makers responsible for damage mitigation and safeguarding of cultural heritage assets.

Conversion of a digital camera into a non-contact colorimeter for use in stone cultural heritage: The application case to Spanish granites

In this study, a digital CMOS camera was calibrated for use as a non-contact colorimeter for measuring the color of granite artworks. The low chroma values of the granite, which yield similar stimulation of the three color channels of the camera, proved to be the most challenging aspect of the task. The appropriate parameters for converting the device-dependent RGB color space into a device-independent color space were established. For this purpose, the color of a large number of Munsell samples (corresponding to the previously defined color gamut of granite) was measured with a digital camera and with a spectrophotometer (reference instrument). The color data were then compared using the CIELAB color formulae. The best correlations between measurements were obtained when the camera works to 10-bits and the spectrophotometric measures in SCI mode. Finally, the calibrated instrument was used successfully to measure the color of six commercial varieties of Spanish granite.

Geological risk assessment of Amtoudi Agadir in southern Morocco: a key case for sustainable cultural heritage

Medieval fortified granaries known as “agadirs” are very common in southern Morocco, being catalogued as world cultural heritage by United Nations. These Berber buildings (made of stones and tree trunks) usually located on rocky promontories, constitute historical testimonials related to the origin of Morocco, and, as tourist attractions, have a positive impact on the local economy. The sustainability of these ancient monuments requires geological-risk evaluations of the massif stability under the agadir with the proposal of stabilization measures, and an architectonic analysis with appropriate maintenance of the structural elements. An interdisciplinary study including climate, seismicity, hydrology, geology, geomorphology, geotechnical surveys of the massif, and diagnosis of the degradation of structural elements have been performed on the Amtoudi Agadir, selected as a case study. The main findings from this study are that the prevalent rocks used for construction (coming from the underlying substratum) are good-quality arkosic sandstones; the SW cliffs under the agadir are unstable under water saturation; some masonry walls are too thin and lack interlocking stones and mortar; and failures in the beams (due to flexure, fracture, and exhaustion in the resistance due to insect attacks or plant roots) are common. The basic risk assessment of ancient buildings of cultural heritage and their geologic substratum are needed especially in undeveloped areas with limited capacity to implement durable conservation policies. Therefore, recommendations have been provided to ensure the stability and maintenance of this important archaeological site.

Teaching-learning process of historical heritage: a Journey as a beginning, path and end

The implantation of new university degrees within the European Higher Education Area implies the need of innovative methodologies in teaching and learning to improve the skills and competencies of students and to answer the growing needs that society continuously demands to heritage management experts. The present work shows an application of the teaching methodology proposed during the international workshop entitled “I International Planning Preservation Workshop. Learning from Al Andalus”, which included the participation of the University of Alicante and Granada, Università Politecnico di Milano and Hunter College City University of New York; where we tried to dissolve traditional boundaries derived of interuniversity cooperation programs. The main objective of the workshop was to discuss and debate the role of urban Historical Centers within the Global Heritage by the integrated work through multidisciplinary teams and the creation of a permanent international working group between these universities to both teach and research. The methodology of this workshop was very participatory and considered the idea of a new learning process generated by "a journey experience." A trip from global to local (from the big city to the small village) but also a trip from the local (historical) part of a big city to the global dimension of contemporary historical villages identified by the students through a system of exhibition panels in affinity groups, specific projects proposed by lecturers and teachers or the generation of publications in various areas (texts, photographs, videos, etc.). So, the participation of the students in this multidisciplinary meeting has enhanced their capacity for self-criticism in several disciplines and has promoted their ability to perform learning and research strategies in an autonomous way. As a result, it has been established a permanent international work structure for the development of projects of the Historical City. This relationship has generated the publication of several books whose contents have reflected the conclusions developed in the workshop and several teaching proposals shared between those institutions. All these aspects have generated a new way of understanding the teaching process through a journey, in order to study the representative role of university in the historical heritage and to make students (from planning, heritage management, architecture, geography, sociology, history or engineering areas) be compromised on searching strategies for sustainable development in the Contemporary City.

The Conservation of our Built Heritage, in Particular Statues in Aberdeen, Evaluated Through a Social and Historical Context and Their Impact, Through the Use of 3D Scanning

Cultural heritage sites all over the world are at risk due to aggressive urban expansion, development, wars and general obsolescence. Not all objects are recorded in detail although they may have social and historical significance. For example more emphasis is placed on the recording of castles and palaces than on crofters’ cottages or tenement blocks, although their history can be just as rich. This paper will investigate the historic fabric of Aberdeen through the use of digital scanning, supported by a range of media including old photographs and paintings. Dissemination of social heritage through visualisations will be explored and how this can aid the understanding of space within the city or specific area. Focus will be given to the major statues/monuments within the context of the city centre, exploring their importance in their environment. In addition studying why many have been re-located away from their original site, the reasons why, and how we have perhaps lost some of the social and historical importance of why that monument was first located there. It will be argued that Digital Media could be utilised for much more than re-creation and re-presentation of physical entities. Digital scanning, in association with visualisation tools, is used to capture the essence of both the cultural heritage and the society that created or used the sites in association with visualisation tools and in some way re-enacting the original importance placed upon the monument in its original location, through adoption of BIM Heritage.

Structural Analysis with ANSYS on Stone Constructions in the Historical Spanish Heritage

According to the importance of rehabilitation and recovery of Architectural Heritage in the live of people, this paper is aimed to strengthen the traditional methods of stone vaults calculation taking advantage of the technological characteristics of the powerful program ANSYS Workbench. As an example of this, it could find out the possible pathologies that could arise during the construction history of the building. To limit this research, the upper vault of the main chapel of the Santiago parish church in Orihuela -Alicante- is selected as a reference which is a Jeronimo Quijano´s important building work in the XVI century in the Renaissance. Moreover, it is an innovative stone masonry vault that consists of 8 double intercrossed arches with each other and braced by severies. During the seventeenth century there was a lantern in the central cap and it is unknown why it was removed. Its construction could justify the original constructive solution with intercrossed arches that freed the center to create a more enlightened and comfortable presbytery. By similarity with other Quijano’s works, it is considered a small lantern drilling the central spherical cap. It is proposed to carry out a comparative study of it with different architectural solutions from the same period and based on several common parameters such as: a vault of square plant with spherical surround, intercrossed arches, a possible lantern, the dimension of the permitted space, similar states of loads and compact limestone masonry. The three solutions are mainly differentiated by their size and the type of lantern and its comparison lets us know which one is the most resistant and stable. The other two building works maintain some connection with the Quijano's professional scope. It has selected the particular case of the Communion chapel of the Basilica in Elche (a large prismatic lantern with a large cylindrical drum that starts from the own arches and an upper hemispherical dome), for its conservation, its proximity to Orihuela and its implementation during the century XVIII. Finally, a significant Dome Spanish Renaissance complete the selection: a cross vault of the Benavides Chapel of the Saint Francisco Convent in Baeza - Jaén-, designed by Andres of Vandelvira in the sixteenth century (a large hemispherical dome that starts from the own arcs). To simplify the calculation and standardize the work that have to be contrasted, all of them were considered with some similar characteristics: 30 cm constant thickness, the intercrossed arches were specifically analyzed and had identical loads, Young's modulus and Poisson's ratio. Regarding the calculation solutions, in general terms, the compressive stresses predominate, influencing on it the joint collaboration of the filling material on the vault, the vault itself, the thick side walls, the buttresses and the top cover weight . In addition, the three solutions are suitable, being the Orihuela one the safest and the Baeza one the riskiest for its large dimensions. Thus, the idea of intercrossed arches with suitable thickness would allow carry out the heaviest lantern and this would confirm it as a Renaissance architectural typology built in stone.

Tourism potential analysis of the castles of Vinalopó, Spain: an opportunity for social and tourist development of cultural heritage

Within the overall framework of the renewal process of coastal tourist destinations, cultural heritage has frequently been used as a key argument for the introduction and development of strategies for the diversification and differentiation of the traditional tourist product based on sun and sand. This is the situation of the province of Alicante, identified with the Costa Blanca geotourism brand, where there are important economic issues that could contribute to the renewal of this coastal tourist destination. One of the most significant heritage values of this space consists of a series of medieval fortresses located along the axis of the Vinalopó River, which has acted since prehistoric times as a natural route from within the provincial mainland to the coast. It is precisely the argument of this historical, territorial and landscape content that has been used repeatedly in recent years to develop initiatives aimed at the creation of a tourist product, currently inexistent, based on the route of the castles of Vinalopó. This communication aims to analyse the degree of tourism potential of the fortresses located in the towns of Biar, Banyeres de Mariola, Sax, Villena, Novelda, Elda, Petrer and Elche, which constitute the core of municipalities where these medieval fortresses are located, finally pointing out some proposals for the creation of a heritage tourism product.
