UN SIT PER IL PPE DEL CENTRO STORICO DI PALERMO: IL CASO STUDIO DEL MANDAMENTO CASTELLAMMARE
2015
In this work a Geographic Information System was realised at the service of municipal administration of Palermo, to integrate, manage and store city plan information regarding the urban district Castellammare whereof detailed executive plan of inner city, correlating basic cartography, current urban instrument, cadastral cartography, current restriction schemes, monumental and historical monuments, street numbers and street network. Quantum GIS vers. 1.8 of Free and Open-Source Software (FOSS) community was exclusively utilized to the fulfilment of GIS. To the experimentation and the fulfilment of WebGIS a free server was used in cloud on the Amazon, where a virtual machine, based on MapSer…
Ottimizzazione di cartografia numerica per GIS
2005
The goal of the current research is to give the definition of standards for structure of digital cartography (relating to different nominal scales and semantic content) compatible with GIS, WEB-GIS, LBS. On the grounds of the critical analysis of those systems and the running of the related software, it was defined a possible model of cartographic structure, applied to a real case. La ricerca, tuttora in corso, è orientata alla definizione di standard di strutturazione della cartografia numerica (in relazione alle diverse scale nominali e al contenuto semantico) compatibile con i GIS, WEBGIS, LBS. Sulla base delle analisi critiche di tali sistemi e del funzionamento dei relativi software è …
CADASTRAL MODELS IN EU MEMBER STATES
2019
Abstract Cadastres are always related to land: they are a creation of man as effect of his relationship with land. The different conditions of the Cadastre in 14 EU Member States, including the former EU Candidate States (that nowadays are also EU members), are shown in this paper. Half of EU countries store cadastral and registration data in the same database. Basically two original models of cadastral system exist in the EU, related with systems of land registration : 1) in the Central European model (beyond the area of the Germanic “Grundbuch”) Cadastre emerges as a graphic basis (map) of land registration (Land Registry), so that physical changes must be reflected in the Cadastre and le…
Cartes et élections : la construction des circonscriptions électorales aux Etats-Unis, entre égalité et équité
2003
Maps and Elections : The Construction of Electoral Districts in the USA. Decennal census-led redistricting in the United States is the occasion for court actions focused nowadays on the political representation of ethnic minorities. Computer tools make possible the building of districts specifically tailored for Blacks or Hispanics, but blatant racial gerrymandering is now rejected by the US Supreme Court. This paper examines the most relevant judicial decisions and describes several local cases.
Information systems for preservation of cultural heritage
2000
The preservation of the cultural heritage has become at present a subject of fundamental importance in Italy, above all because of the numerous unhappy events, due to not only natural reasons, happened in these last years. Besides this problem is particularly urgent in Sicily, because of the existence of a considerable cultural heritage and in absence of a complete and systematic inventory. To tackle such a complex subject, the use of informatics is required, since the traditional methods, based especially on paper documentation, are absolutely inadequate. Particularly, this work deals with the cultural heritage inventory selected according to: - historical urban centres; - archaeological s…
ISIS: a semantic mediation model and an agent based architecture for GIS interoperability
2003
The diversity of spatial information systems promotes the need to integrate heterogeneous spatial or geographic information systems (GIS) in a cooperative environment. The paper describes the research project ISIS (Interoperable Spatial Information System) which is a semantic mediation approach to support GIS interoperability. Its key characteristic is a dynamic resolution of semantic conflicts which is adequate for achieving autonomy, flexibility and extensibility. We propose a spatial OO data model and a mediation architecture based on multi-agent paradigm to support GIS interoperability.
A GIS-based method for evaluating the walkability of a pedestrian environment and prioritised investments
2020
Abstract Despite the large investments made in the construction and modernisation of railway infrastructure, poor quality pedestrian routes may discourage users from using public transport. In fact, very little attention is generally paid to pedestrian mobility. Therefore, a method for evaluating the quality of pedestrian paths and the accessibility to railway stations has been developed. This method considers the main factors influencing the walkability of an urban area and makes it possible to establish the priorities for intervention, i.e. to identify the arcs of a pedestrian network that require prioritised action. The methodology is a decision support tool that can be used by policymak…

Automatic research of the capitalization rate for the residential automated valuation: an experimental study in Cosenza (Italy).
2017
When a market oriented approach is not applicable because of the lack of comparable sales data (Ciuna et al. 2014a), International Valuation Standards suggest the use of the Income Approach, which has the task of simulating the market through an economic and financial scheme. The central question of this approach is due to the quantification of the capitalization rate, whereas it is generally extracted in a market segment different from that of the subject. This paper intends to propose an automated valuation model of the capitalization rate based on a real estate database built through a computerized geocoding automatic procedure, starting from the application of statistical models of mult…
