Il colore delle "architetture urbane" di Asmara: conservazione e valorizzazione
No full textIl colore dei fronti, unitamente all’intonaco e al suo supporto, viene oggi considerato documento/monumento testimonianza per l’intrinseco valore materiale, ma anche immateriale, che riconduce ad una “cultura del fare”, affinata nel tempo, irripetibile e non riproducibile.
Il valore del colore delle architetture della città di Asmara trova riscontro nella storia architettonica ed urbanistica dei suoi tessuti edilizi, si fonda su un’approfondita analisi storica delle fonti dirette e indirette e necessariamente su rilievi alla scala del progetto, si basa sulla conoscenza delle tecniche costruttive, dei materiali utilizzati e delle valenze cromatico-decorative dei fronti, valutandone anche le situazioni di degrado esistenti.
Questo percorso teorico/operativo vede mutare l’atteggiamento verso le superfici dell’architettura da meri strati di sacrificio - disinvoltamente sostituiti perché ritenuti semplici protezioni del supporto sottostante - a materia signata degna di essere conservata in quanto testimonianza dei segni che l’uomo e il tempo vi hanno impresso

Specifiche tecniche per il rilievo delle aree verdi nell'ambito del GIS tematico del comune di Milano
No full textThe pourpose of this work, started with the Progetto Verde Milano in 2004, is the definition of the measuring procedure and of the statement of contents to use to implement the topographic database of the green areas with the ones step by step acquired by the Administration of Milan.The data thus
collected will respect the conditions that allow the correct updating of the GIS of the green areas.
The statement has been edited at first to allow the conversion from CAD files, which cannot be used to implement a thematic GIS, into a shapefile, which is the proper file for a GIS.
The document is divided in three parts:
1. technical statement for topographic measuring;
2. contents statement;
3. supplying and graphic reproduction of data.
The first part defines the aspects concerning the topographic measuring, specifying the operative steps of the measure taking, the instruments to use, the metrical precision required for every different kind of objects and the positioning procedure in the correct coordinate system.
The second part concerns the structure of the database and the definition of the thesaurus of the objects to be measured, in such a way that they correspond to those used in the GIS of the green areas.
The third part defines the features of the measuring output, in order to test the conformity of the final data to the measuring and contents specificatios. The structure of this statement makes possible the creation of omogeneous files from different sources. In this way the implementation with new areas follows unique and standard procedure and can be easily managed, as well as correctly represented in the correspondent WebGIS. The format and the contents are conform to the indications IntesaGIS and to the Regional content statement
CONSERVATION AND VALORIZATION OF THE HISTORICAL HERITAGE THROUGH LASER SCANNER TECNOLOGY
Full text linkIn Italy there is a very widespread multitude of buildings important and interesting in the field of Cultural Heritage. Several of them have been abandoned in the last decades and now they show all the deterioration and the structural damages due to abandon. This is also the case of about forty traditional farmsteads located in the close suburbs of the city of Milano and belonging to the local administration. Among these farmsteads, Cascina Linterno, for its rich historical background going back to the 14th century and
earlier, was chosen to carry out a test in the planning process with the participation of local associations under the supervision of a group of experts in the field of structural assessment, preservation and design from Politecnico of Milan. Time and resources saving and effectiveness of appropriate activities is the main guideline of this process, where the first step consists necessarily on the topographical survey. The choice of Terrestrial Laser Scanner to carry out the survey complied naturally most necessities, but it was also meant to provide new hallenges in the fruition of the point cloud by groups of experts without topographical knowledge. The aim is to analyze the procedures and the output needed by the different specialists involved in this kind of intervention on Cultural Heritage, in order to provide friendly tools to work directly on the point cloud, taking advantage of its rapidity in acquisition and of its richness of details, thus avoiding the production of traditional “lossy” layouts
