Methodology for the metric restoration of the historical cartography applied to Francisco Coello's cartografic series of the Royal Site of Aranjuez

Hojas Kilométricas (Kilometric Sheets). Specifically, the study focuses on those sheets referring to the city centre and surrounding area of the Royal Site of Aranjuez, a town in the south of the Province of Madrid. The aim of this study is to restore the actual size and measurements of scanned images of the Hojas Kilométricas. This would allow us, among other things, to reestablish both the format and scale of the original plans. To achieve this goal it is necessary to rectify and then georeference these images, i.e. assign them a geographic reference system. This procedure is essential in the overlaying and comparison of the Hojas Kilométricas of the Royal Site with other historical cartography as well as other sources related to the same area from different time periods. Subsequent research would allow us, for example, to reconstruct the time-evolution of the urban area, to spot new construction and to pinpoint the locations of any altered or missing buildings or architectural features. In addition, this would allow us to develop and integrate databases for GIS models applicable to the management of our cultural heritage.

GIS analysis of the accuracy of Tomas Lopez's historical cartography in the Canary Islands (1742 - 1746)

The accuracy of Tomás López´s historical cartography of the Canary Islands included in the “Atlas Particular” of the Kingdoms of Spain, Portugal and Adjacent Islands” is analyzed. For this purpose, we propose a methodology based on Geographic Information Systems (GIS), a comparison of digitized historical cartography population centres with current ones. This study shows that the lineal error value is small for the smaller islands: Lanzarote, El Hierro, La Palma and La Gomera. In the large islands of Tenerife, Fuerteventura and Gran Canaria, the error is smaller in central zones but increases towards the coast. This indicates that Tomás López began his cartography starting from central island zones, accumulating errors due to lack of geodetic references as he moved toward the coast.

GIS analysis for the study of rural depopulation: the Kingdom of Valencia (Tomas Lopez 1789)

One of the more aspects that have shaped the landscape is the human impact. The human impact has the clearest indicator of the density of settlements in a particular geographic region. In this paper we study all settlements shown on the map of the Kingdom of Valencia, Spain Geographic Atlas (AGE) of Tomas Lopez (1788), and their correspondence with the current ones. To meet this goal we have developed a specific methodology, the systematic study of all existing settlements in historical cartography. This will determine which have disappeared and which have been renamed. The material used has been the historical cartography of Tomas Lopez, part of the AGE (1789), the Kingdom of Valencia (1789), sheets numbers (78, 79, 80 and 81); Current mapping of the provinces of Alicante, Valencia, Castellon, Teruel, Tattagona and Cuenca; As main software ArcGis V.9.3. The steps followed in the methodology are as follows: 1. Check the scale of the maps. Analyze the possible use of a spherical earth model. 2. Geo-reference of maps with latitude and longitude framework. Move the historical longitude origin to the origin longitude of modern cartography. 3 Digitize of all population settlements or cities. 4 Identify historic settlements or cities corresponding with current ones. 5. If the maps have the same orientation and scale, replace the coordinate transformation of historical settlements with a new one, by a translation in latitude and longitude equal to the calculated mean value of all ancient map points corresponding to the new. 6. Calculation of absolute accuracy of the two maps, i.e. the linear distance between the points of both maps. 7 draw in the GIS, the settlements without correspondence, in the current coordinates, and with a circle of mean error of the sheet, in order to locate their current location. If there are actual settlements exist within this circle, they are candidates to be the searched settlements. We analyzed more than 2000 settlements represented in the Atlas of Tomas Lopez of the Kingdom of Valencia (1789), of which almost 14.5% have no correspondence with the existing settlements. The rural landscape evolution of the Valencia, oldest kingdom of Valencia, one can say that can be severely affected by the anthropization suffered in the period from 1789 to the present, since 70% of existing settlements actually have appeared after Tomas Lopez¿s cartography, dated on 1789

Entornos termodinámicos. Una cartografía crítica en torno a la energía y la arquitectura

En los últimos años, y a la luz de los retos a los que se enfrenta la sociedad, algunas voces están urgiendo a dejar atrás los paradigmas modernos —eficiencia y rendimiento— que sustentan a las llamadas prácticas sostenibles, y están alentando a repensar, en el contexto de los cambios científicos y culturales, una agenda termodinámica y ecológica para la arquitectura. La cartografía que presenta esta tesis doctoral se debe de entender en este contexto. Alineándose con esta necesidad, se esfuerza por dar a este empeño la profundidad histórica de la que carece. De este modo, el esfuerzo por dotar a la arquitectura de una agenda de base científica, se refuerza con una discusión cultural sobre el progresivo empoderamiento de las ideas termodinámicas en la arquitectura. Esta cartografía explora la historia de las ideas termodinámicas en la arquitectura desde el principio del siglo XX hasta la actualidad. Estudia, con el paso de los sistemas en equilibrio a los alejados del equilibrio como trasfondo, como las ideas termodinámicas han ido infiltrándose gradualmente en la arquitectura. Este esfuerzo se ha planteado desde un doble objetivo. Primero, adquirir una distancia crítica respecto de las prácticas modernas, de modo que se refuerce y recalibre el armazón intelectual y las herramientas sobre las que se está apoyando esta proyecto termodinámico. Y segundo, desarrollar una aproximación proyectual sobre la que se pueda fundamentar una agenda termodinámica para la arquitectura, asunto que se aborda desde la firme creencia de que es posible una re-descripción crítica de la realidad. De acuerdo con intercambios de energía que se dan alrededor y a través de un edificio, esta cartografía se ha estructurado en tres entornos termodinámicos, que sintetizan mediante un corte transversal la variedad de intercambios de energía que se dan en la arquitectura: -Cualquier edificio, como constructo espacial y material inmerso en el medio, intercambia energía mediante un flujo bidireccional con su contexto, definiendo un primer entorno termodinámico al que se denomina atmósferas territoriales. -En el interior de los edificios, los flujos termodinámicos entre la arquitectura y su ambiente interior definen un segundo entorno termodinámico, atmósferas materiales, que explora las interacciones entre los sistemas materiales y la atmósfera interior. -El tercer entorno termodinámico, atmosferas fisiológicas, explora los intercambios de energía que se dan entre el cuerpo humano y el ambiente invisible que lo envuelve, desplazando el objeto de la arquitectura desde el marco físico hacia la interacción entre la atmósfera y los procesos somáticos y percepciones neurobiológicas de los usuarios. A través de estos tres entornos termodinámicos, esta cartografía mapea aquellos patrones climáticos que son relevantes para la arquitectura, definiendo tres situaciones espaciales y temporales sobre las que los arquitectos deben actuar. Estudiando las conexiones entre la atmósfera, la energía y la arquitectura, este mapa presenta un conjunto de ideas termodinámicas disponibles —desde los parámetros de confort definidos por la industria del aire acondicionado hasta las técnicas de acondicionamiento pasivo— que, para ser efectivas, necesitan ser evaluadas, sintetizadas y recombinadas a la luz de los retos de nuestro tiempo. El resultado es un manual que, mediando entre la arquitectura y la ciencia, y a través de este relato histórico, acorta la distancia entre la arquitectura y la termodinámica, preparando el terreno para la definición de una agenda termodinámica para el proyecto de arquitectura. A este respecto, este mapa se entiende como uno de los pasos necesarios para que la arquitectura recupere la capacidad de intervenir en la acuciante realidad a la que se enfrenta. ABSTRACT During the last five years, in the light of current challenges, several voices are urging to leave behind the modern energy paradigms —efficiency and performance— on which the so called sustainable practices are relying, and are posing the need to rethink, in the light of the scientific and cultural shifts, the thermodynamic and ecological models for architecture. The historical cartography this PhD dissertation presents aligns with this effort, providing the cultural background that this endeavor requires. The drive to ground architecture on a scientific basis needs to be complemented with a cultural discussion of the history of thermodynamic ideas in architecture. This cartography explores the history of thermodynamic ideas in architecture, from the turn of the 20th century until present day, focusing on the energy interactions between architecture and atmosphere. It surveys the evolution of thermodynamic ideas —the passage from equilibrium to far from equilibrium thermodynamics— and how these have gradually empowered within design and building practices. In doing so, it has posed a double-objective: first, to acquire a critical distance with modern practices which strengthens and recalibrates the intellectual framework and the tools in which contemporary architectural endeavors are unfolding; and second, to develop a projective approach for the development a thermodynamic agenda for architecture and atmosphere, with the firm belief that a critical re-imagination of reality is possible. According to the different systems which exchange energy across a building, the cartography has been structured in three particular thermodynamic environments, providing a synthetic cross-section of the range of thermodynamic exchanges which take place in architecture: -Buildings, as spatial and material constructs immersed in the environment, are subject to a contiuous bidirectional flow of energy with its context, defining a the first thermodynamic environment called territorial atmospheres. -Inside buildings, the thermodynamic flow between architecture and its indoor ambient defines a second thermodynamic environment, material atmospheres, which explores the energy interactions between the indoor atmosphere and its material systems. -The third thermodynamic environment, physiological atmospheres, explores the energy exchanges between the human body and the invisible environment which envelopes it, shifting design drivers from building to the interaction between the atmosphere and the somatic processes and neurobiological perceptions of users. Through these three thermodynamic environments, this cartography maps those climatic patterns which pertain to architecture, providing three situations on which designers need to take stock. Studying the connections between atmosphere, energy and architecture this map presents, not a historical paradigm shift from mechanical climate control to bioclimatic passive techniques, but a range of available thermodynamic ideas which need to be assessed, synthesized and recombined in the light of the emerging challenges of our time. The result is a manual which, mediating between architecture and science, and through this particular historical account, bridges the gap between architecture and thermodynamics, paving the way to a renewed approach to atmosphere, energy and architecture. In this regard this cartography is understood as one of the necessary steps to recuperate architecture’s lost capacity to intervene in the pressing reality of contemporary societies.

Integration of Virtual Map Rooms as a support tool in historical and social research

At the present time almost all map libraries on the Internet are image collections generated by the digitization of early maps. This type of graphics files provides researchers with the possibility of accessing and visualizing historical cartographic information keeping in mind that this information has a degree of quality that depends upon elements such as the accuracy of the digitization process and proprietary constraints (e.g. visualization, resolution downloading options, copyright, use constraints). In most cases, access to these map libraries is useful only as a first approach and it is not possible to use those maps for scientific work due to the sparse tools available to measure, match, analyze and/or combine those resources with different kinds of cartography. This paper presents a method to enrich virtual map rooms and provide historians and other professional with a tool that let them to make the most of libraries in the digital era.
