Transformaciones urbanas en torno a las reales puertas de la Villa de Madrid (1656-1860)

La estructura urbana de Madrid comenzó a dibujarse con los primeros asentamientos fortificados del siglo IX. Sus posteriores ampliaciones estuvieron acotadas por los sucesivos recintos que delimitaron los contornos de una capital en constante expansión. De carácter inicialmente defensivo, luego fiscal y sanitario, estas estructuras estuvieron articuladas en torno a las puertas de acceso a la Villa, estableciendo un sistema general de cerramiento y comunicación que permitiera el control de personas y mercancías en su tránsito hacia el interior de la ciudad. La modestia inicial con que las puertas y tapias del recinto edificado en tiempos de Felipe IV desempeñaron sus funciones de espaldas al exterior de la Villa fue remplazada por un creciente protagonismo, de carácter simbólico y ornamental, que trascendió a su propia arquitectura para inspirar algunas de las importantes transformaciones urbanas operadas en su entorno. Relacionada principalmente con el ideal ilustrado de embellecimiento de la ciudad, la renovación de sus puertas principales se completaba con la reedificación y regularización de sus cercas, y la conformación de nuevos paseos en las afueras de la capital, cuyo trazado vertebrará en buena medida la ocupación de la periferia y la consiguiente definición de la trama urbana del Madrid de hoy. El presente trabajo de investigación indaga sobre la significación urbana de las Reales Puertas de la Villa de Madrid, a partir de la revisión de su establecimiento en los sucesivos recintos de la capital, con especial atención a las transformaciones urbanas operadas en ella desde la definición de su último límite hasta la proyección futura del Madrid ampliado según el anteproyecto de Carlos Mª de Castro. La observación conjunta de las componentes arquitectónica y urbana de las puertas de la Villa de Madrid se ofrece a partir de un relato cronológico de los hechos, fundamentado en su justificación documental y la secuencia visual registrada en la cartografía histórica de la ciudad. La incorporación de aportaciones gráficas de nueva elaboración, de carácter y alcance diversos, proporciona una superposición espacio-temporal que posibilita la lectura comparada de las arquitecturas de las Reales Puertas de la Villa de Madrid y de las transformaciones urbanas operadas a partir de ellas, determinantes en gran medida la configuración de la ciudad actual. ABSTRACT Madrid’s current urban structure has its roots in the first fortified settlements of the IX century. Its subsequent expansions due to the capital’s constant growth were limited by successive enclosures, built originally as a defense mechanism, but later used for fiscal and sanitary purposes as well. The construction of these structures pivoted around the gates that gave access to the city, establishing an enclosure that allowed control of both people and goods on their way into the city. The gates and walls originally built by Felipe IV performed their purpose with a modesty that was later replaced by an increasing symbolic and ornamental prominence, eventually surpassing their own architecture to inspire profound urban changes around them. With the purpose of embellishing the city, the main gates were renovated, the walls were rebuilt and standardized, and new avenues were laid out outside the city. These changes dictated in large part the settling on the suburbs and the resulting configuration of Madrid’s urban scene as we know it today. This research explores the urban significance of the Royal Gates of Madrid through the study of the enclosures that marked the limits of the city. Special attention is given to the urban changes since the last enclosure was established through to Carlos Mª de Castro’s draft for Madrid’s future projection. The architectonic and urban facets of Madrid’s gates are examined simultaneously in a series of chronological events, based on relevant documentation and the graphical record found in Madrid’s historic cartography. This thesis includes new graphic contributions, which allow the comparison of the architecture of the Royal Gates of Madrid as they evolved in time and space. These documents are essential in order to understand the urban transformations that took place based on the Gates, having largely determined the city’s current configuration.

Traditional Building Adaptation to New Requirements: Historic Center of Arequipa, Perú

The traditional buildings in the historic center of the city of Arequipa, Perú, recently declared of human heritage, are of volcanic tuff both in walls and in vaulted roofs on the ground floor. Having been built in the 18th century and up to the beginning of the 20th century, they have suffered many damages from the seismic movements registered in this region. Due to this, many of them have had to be rebuilt. In this presentation, the different changes to adapt the city of Spanish colonial origin to the present tertiary use are analyzed.

Similarities and Differences in Barrel Vaults of Traditional and Stately Houses in the Historic Centre of Arequipa, Perú

The traditional architecture of the centre of the city of Arequipa has been analyzed by comparing floor-plans of houses from the eighteenth and nineteenth centuries in order to explain the reasons behind the arrangement of their constructional elements and the evolution of said elements and floor-plans. The historic centre of Arequipa, a city located in the South of Perú, South America (Latitude 16°23' South, Longitude 71 °31' West), is based on a ground plan from 1540 that was set during the city's Spanish foundation. It was declared Patrimony of the Humanity by UNESCO. The manorial architecture is widely known for its decorated fronts and one-of-a-kind designs, but its differences with respect to the popular architecture are not based exclusively on decorative aspects. Peru's colonial period finished around 1825, but the barrel-vault, construction style continued in Arequipa through 1868, when an earthquake destroyed the city. Thereafter, the vaults were replaced by roofs made of rails, with cinders made out of the lava stone. The stately houses belonged to the founding families who settled around the main square on forty nine blocks that formed a square-grid, street layout. Also belonging to this category are the houses of landlords and traders from post-colonial times.

Learning&Information Technologies Cartography

Nowadays, many researches focus their efforts in studies and applications on the Learning area. However, there is a lack of a reference system that permits to know the positioning and the existing links between Learning and Information Technologies. This paper proposes a Cartography where explains the relationships between the elements that compose the Learning Theories and Information Technologies, considering the own features of the learner and the Information Technologies Properties. This intersection will allow us to know what Information Technologies Properties promote Learning Futures.

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.

Cartography for cooperative manoeuvres with autonomous land vehicles

This article presents a cartographic system to facilitate cooperative manoeuvres among autonomous vehicles in a well-known environment. The main objective is to design an extended cartographic system to help in the navigation of autonomous vehicles. This system has to allow the vehicles not only to access the reference points needed for navigation, but also noticeable information such as the location and type of traffic signals, the proximity to a crossing, the streets en route, etc. To do this, a hierarchical representation of the information has been chosen, where the information has been stored in two levels. The lower level contains the archives with the Universal Traverse Mercator (UTM) coordinates of the points that define the reference segments to follow. The upper level contains a directed graph with the relational database in which streets, crossings, roundabouts and other points of interest are represented. Using this new system it is possible to know when the vehicle approaches a crossing, what other paths arrive at that crossing, and, should there be other vehicles circulating on those paths and arriving at the crossing, which one has the highest priority. The data obtained from the cartographic system is used by the autonomous vehicles for cooperative manoeuvres.

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

El Entorno Aumentado: Imperativo informacional para una ecología digital de lo arquitectónico

Esta tesis se suma a los intentos teóricos de clarificar la impronta del dominio digital en lo arquitectónico. Propone una cartografía crítica para reconstruir el proceso de tal convergencia considerando aquellos acontecimientos reveladores que lo han pautado. La integración de la extensión digital propia las tecnologías de la información y la comunicación en el contexto tradicional arquitectónico ha supuesto el advenimiento de un ecosistema artificial complejo. A esta realidad o proceso concurrente se la denomina el Entorno Aumentado. La línea principal de investigación explora el desarrollo de la interacción hombre-máquina, en sendas trayectorias sincrónicas convergentes. El análisis se aborda por tanto desde la consideración de esa naturaleza dual, atendiendo simultáneamente a la humanización del dominio digital o cómo la computación se adapta a la condición natural de ser humano, y a la digitalización del ser humano o cómo éste asume el imperativo digital. El análisis resulta vertebrado desde la condición panóptica del punto de observación del acontecimiento: la cuarta pared, entendida como pantalla y punto de inflexión que estructura la convergencia de los entornos físico y digital. La reflexión acometida sobre la construcción del Entorno Aumentado procura la verificación de la tesis, que es central en esta investigación: la multiplicación dimensional del lugar físico mediante su extensión con un campo informacional procedente del dominio digital, y sus efectos en la construcción de la nueva ecología digital propia del Entorno Aumentado. Esta circunstancia se produce tras la eclosión de la Revolución Digital en la segunda mitad del siglo XX, el consecuente incremento de la interacción entre los entornos digital y físico, y el alcance de un nivel superior de comunicación en los procesos arquitectónicos. Los síntomas del Entorno Aumentado se hacen notar en nuestra contemporaneidad; en ese sentido, la tesis alcanza un diagnóstico del cambio. La fractura y obsolescencia del límite espacio-temporal establecido por las dicotomías históricas privado-público, casa-ciudad, trabajo-ocio,…etc., o la vigencia del proyecto procedimental son algunas de sus consecuencias en el modo de abordar la disciplina arquitectónica. Abstract This dissertation aims to complete the theoretical attempts to clarify the digital domain imprint on the architectural realm. It constructs a critical cartography to reconstruct the process of such convergence, considering those principal events who have scheduled it. The integration of TIC’s digital extension through the traditional architectural context has meant the advent of an artificial complex ecosystem. This reality or concurrent process is called The Augmented Environment. The key research attempt explores man-machine interaction process in both synchronous converging trajectories. The analysis therefore addresses from the consideration of this dual nature, focusing simultaneously in humanizing digital domain process or how the computer fits the natural condition of human beings, and in digitalizing human beings or how it affords the digital imperative. The analysis is structured from the panoptic condition of the event scope: the fourth wall as screen that structures the convergence of physical and digital environments. The examination of The Augmented Environment’s assembly pretends the verification of the central point of this research: the dimensional multiplication of physical space by extending informational fields from the digital domain, and its effects on the construction of the Augmented Environment new digital ecology. This circumstance occurs after the arrival of the Digital Revolution in the second half of the twentieth century, with the consequent increase in the interaction between digital and physical environments, and the reach of a higher level of communication in architectural processes. The Augmented Environment signs are alive nowadays; in that sense, the thesis reaches a diagnostic of the changes. The fracture and obsolescence of the time-space limit established by historic dichotomies as private-public, home-city, working-leisure...etc., or the validity of the procedural design are some of its consequences on the architectural discipline.

GIS for cartographic accuracy analysis of settlements in the province of Madrid (AGE Tomas Lopez 1804).

Purpose: In this paper we study all settlements shown on the map of the Province of Madrid, sheet number 1 of AGE (Atlas Geográfico de España of Tomas Lopez 1804) and their correspondence with the current ones. This map is divided in to zones: Madrid and Almonacid de Zorita. Method: The steps followed in the methodology are as follow: 1. Geo-reference of maps with latitude and longitude framework. Move the historical longitude origin to the origin longitude of modern cartography. 2 Digitize of all population settlements or cities (97 on Madrid and 42 on Almonacid de Zorita), 3 Identify historic settlements or cities corresponding with current ones. 4. 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. 5. Calculation of absolute accuracy of the two maps. 6 draw in the GIS, the settlements accuracy. Result: It was found that all AGE settlements have good correspondence with current, ie only 27 settlements lost in Madrid and 2 in Almonacid. The average accuracy is 2.3 and 5.7 km to Madrid and Almonacid de Zorita respectively. Discussion & Conclusion: The final accuracy map obtained shows that there is less error in the middle of the map. This study highlights the great work done by Tomas Lopez in performing this mapping without fieldwork. This demonstrates the great value that has been the work of Tomas Lopez in the history of cartography.

Promotion of intangible heritage as a tool to strengthen revitalisation of historic centres: the case of de Monumenta Programme in the City of Porto Alegre (Rio Grande do Sul State) Brazil

The preservation of tangible cultural heritage does not guarantee effective revitalisation of urban historic areas as a whole. The legacy of our history consists not only of paintings, sculptures, architectural monuments and public spaces, but also the safeguarding of immaterial aspects of social life, such as oral traditions, rituals, practices, knowledge and craft skills. From 1999 to 2013, 26 Brazilian cities benefited from the Monumenta Programme - a national cultural policy that involved institutions, the private sector and the local community. The purpose of the programme was to stimulate economic growth and increase cultural and social development of the historic centres. Moreover, it sought to increase the number of residents in the benefited areas as defined in its agenda (IDB, 1999; MinC & Programa Monumenta, 2006). Using the Historic Centre of Porto Alegre as a case study, this paper examines how this cultural programme enables demographic change through the promotion of intangible cultural heritage, e.g. by supporting educational projects. The demographic flow was analysed using the microdata of the Populations Censuses (years 2000 and 2010) available from the Brazilian Institute of Geography and Statistics. The results showed an increase in low-income residents the areas that participated in the programme. This increase may have been motivated by a set of cultural-educational projects under the auspices of the Monumenta Programme. The retraining of artisans of Alfândega Square, the training of low-income youth for restoration work and the implementation of the "Black Route Museum in Porto Alegre" (Bicca, 2010) are just some examples of what was done to improve the local community's economy, to encourage social cohesion and to enhance the awareness of cultural diversity as a positive and essential value in society.
