    Abstract. Railways were a key mode of transporting goods and people for industrial and urban development in the late modern age. Their special part in economic growth comes with their role in the development of cultural heritage along their pathways. However, because of competing urban construction, many railway heritages are in danger, such as the Yunnan-Vietnam Railway (YVR) in China, an important international narrow-gauge railway built in 1901, acknowledged as a railway heritage in 2018. As a typical linear heritage, the railway integrates both the natural and cultural landscapes, related to the large spatial extent and complex composition of single heritage elements. Geographic Information Systems (GIS) offer a great support in the investigation, assessment, and management of railway heritage. In this research, the huge cultural heritage related to the YVR was studied using a combined geo-historical and GIS approach. This paper aims to 1) give a brief review of the current status of the application of GIS on linear railway heritages studies, including heritage resources surveys, spatial analysis, thematic mapping and public service, 2) introduce the case study of the Yunnan-Vietnam Railway, and 3) present a geodatabase design for the Yunnan-Vietnam Railway heritage management.</p

    The current work models urban growth in the continuous built-up areas of 47 Spanish cities from the mid-nineteenth century through to the present day. We did this by compiling a comprehensive Geographic Information System (GIS) dataset, based on a series of historic maps and aerial images, and then used this to study urban growth and to make spatial comparisons. Our chosen indicator of expansion: population density, was calculated by dividing the total population of each city (based on its municipal area) by its built-up area during each period. Our results revealed four different stages of growth, each of which was characterised by a certain political and economic reality. They showed the clogging up of the walled city, the shaping of the urban ensanches, the maturity of the compact city and the process of metropolisation

    The GIS Architecture Elements for the Coastal Areas Along the Adriatic Sea

    The study of the national and cross-border Adriatic coastal areas will be approached by using an interdisciplinary method. A comparative reading will focus on an analysis of the main variations undergone by the area and will try to define all the elements involved in those areas where a conflicting presence exists between high quality environmental factors on the one hand and anthropological aggression on the other. In this paper we present the aim of the GES.S.TER. project, that is the creation of a protocol for territorial analysis – namely the G.I.S.A.E. Adriatic (Geographical Information System for Activities along the Coast). The Project is financed by the Interreg IIIA Programme Adriatic Cross Border from 2004 to 2007 (prof. Donatella Cialdea is the Head of GESS.S.TER.). Moreover the Project will be a case-study analysed by the GISIG - Geographical Information Systems International Group. The areas covered by the project include the national Adriatic coast, in particular the coastal area of Molise, and the cross-border coasts of Albania and Croatia (both partners in the project). In the definition of the characteristics that a territorial information system of aid to the GES.S.TER project should have, the parameters for the collection of data and for the reordering of the information, which was already in our possession, have been established. Another necessary step has been that of revising and coordinating the existing sources, keeping in mind that the final purpose of the system is to define the objective landscape qualities, we find ourselves having to face the problem of combining, and consequently, comparing, information coming from different sources. Five resource systems have been selected: physical-environmental; landscape-visual; historical-cultural; agricultural-productive; Demographic-tourism. A further source of information comes from the analysis carried out during the drawing up of the Vast Area Environmental Landscape Territorial Plans and we have defined the criteria for the selection of the indicators. These indicators will be useful for an evaluation of transformations through time of the territories, in order to prepare the documents for the strategic environmental assessment procedures too.

    FORMALIZING INFORMALITY: THE PRAEDIAL REGISTRATION SYSTEM IN PERU

    Get PDF
    The Praedial Property Registration system has been presented as an alternative system to traditional registries for the formalization of immovable property. Much of the earlier design and pilot work for the Praedial Property Registration system was done by the Peruvian private organization, Instituto Libertad y Democracia (ILD). They claim that in Peru they "have formalized over 150,000 properties much more quickly, and at dramatically less costs, than traditional titling and registration programs" in three-and-a-half years during the early 1990s. This property formalization system has been trademarked as PROFORM. It is being offered to other countries as a quick and inexpensive way to convert informal property in the hands of a large proportion of the population into legally recognized private property, and as a source of capital for the grassroots development of these countries. This study assesses the functioning of this system in Peru and its replicability in other countries. There is no easily accessible documentation on how this property formalization program has actually functioned in Peru, and it is therefore difficult for development agencies to determine its applicability elsewhere. This assessment of the Registro Predial in Peru is an attempt to document the functioning of an important component of this formalization program. The study examines different aspects of property formalization and related institutions and processes. The scope of this assessment, therefore, includes not only the Registro Predial registration system, but also the titling process (prior to registration) and the credit worthiness and credit opportunities for titled and registered property in both urban and rural areas in Lima that fall under the jurisdiction of the Registro Predial. The study also examines the concepts and legal framework of titling, registration, ownership rights, and possession rights within the Peruvian context.Land titles--Registration and transfer--Peru, Land tenure--Government policy--Peru, Land administration--Peru, Land Economics/Use,

    NATMAP – Canada’s National Geoscience Mapping Program: 1991 – 2003

    Get PDF
    The National Geoscience Mapping Program (NATMAP) was developed by the Geological Survey of Canada (GSC) in 1991 to support Canada’s natural resources industry by filling gaps in the fundamental geoscience database, and to respond to emerging environmental and societal issues. The 12-year, multi-million dollar program operated through close collaboration between the GSC and the provincial and territorial geoscience agencies; it also incorporated participation from universities and some support from industry. Projects ranged from mapping and assessing the surficial geology of the Oak Ridges Moraine in Greater Toronto, documenting the geological framework of the Slave Province in the Northwest Territories, to research on the evolution of oil and gas in the Magdalen Basin off Canada’s east coast. The program, whose thirteen projects included components in nine provinces and three territories, came to a successful end in 2003. Now, almost twenty years after fieldwork began on the first of the NATMAP projects, impacts of this major contribution to Canada’s geoscience realm have been recognized from several perspectives. As expected, a wealth of new, high-quality geoscience knowledge was acquired for various areas across Canada, knowledge that became and remained readily accessible. Early socio-economic impacts from applying this knowledge can now be recognized and documented. In addition, NATMAP’s legacy must also include recognition of how it led to establishing an important and effective framework under which cooperative and collaborative geoscience is designed and conducted by GSC and provincial and territorial geoscience agencies, and also how the organization of NATMAP became the first step in the evolution of the way in which the GSC plans and undertakes the whole of its geo-science program in response to meeting the varied geoscience needs of Canadians. Perhaps a final testament to the success of NATMAP resides with many of this country’s young geologists, now following professional careers in the public and private sectors, who received invaluable training as student participants in one or another of the NATMAP projects. SOMMAIRE Le Programme national de cartographie scientifique (NATMAP) a Ă©tĂ© dĂ©veloppĂ© en 1991 par la Commission gĂ©ologique du Canada (CGC) en appui Ă  l’industrie des richesses naturelles en comblant les lacunes de la base de donnĂ©es gĂ©oscientifiques, et pour ĂȘtre en mesure de rĂ©pondre aux problĂšmes sociaux et environnementaux Ă©mergeants. Ce programme de plusieurs millions de dollars Ă©talĂ© sur 12 ans a Ă©tĂ© mise en Ɠuvre en Ă©troite collaboration entre la CGC, les services gĂ©oscientifiques des provinces et des territoires; il y a Ă©galement eu participation d’universitĂ©s ainsi qu’une certaine collaboration du secteur privĂ© de l’industrie. Les projets allaient de la cartographie et de l’étude de la gĂ©ologie des dĂ©pĂŽts meubles de la moraine d’Oak Ridge dans la rĂ©gion du Grand Toronto, Ă  la documentation de la structure gĂ©ologique de la Province des Esclaves dans les Territoires du Nord-Ouest, Ă  la recherche sur l’évolution du pĂ©trole et du gaz dans le bassin de la Madeleine au large de la cĂŽte Est du Canada. Ce programme dont les treize projets comportaient des composantes dans neuf provinces et trois territoires s’est terminĂ© avec succĂšs en 2003. Maintenant, prĂšs de vingt ans aprĂšs le dĂ©but des premiers travaux de terrain des premiers projets, les retombĂ©es dans le domaine gĂ©oscientifique sont reconnues et ce de diffĂ©rents point de vue. Comme il fallait s’y attendre, une abondance de nouvelles connaissances gĂ©oscientifiques de haute qualitĂ© ont Ă©tĂ© ainsi acquises de diverses rĂ©gions du Canada et sont dĂ©sormais disponibles. On peut dĂ©jĂ  mesurer et documenter les premiĂšres retombĂ©es socio-Ă©conomiques dĂ©coulant de l’application de ces connaissances. C’est aussi NATMAP qui a permis l’édification d’un important et efficace rĂ©seau de collaboration et de coopĂ©ration permettant la planification et la rĂ©alisation de projets gĂ©oscientifiques menĂ©s par la CGC et les services gĂ©oscientifiques des provinces et des territoires. Il faut aussi reconnaĂźtre comment l’organisation de NATMAP a Ă©tĂ© la premiĂšre Ă©tape de l’élaboration de la façon dont la CGC planifie et dĂ©fini l’ensemble de sa programmation gĂ©oscientifique afin de rĂ©pondre aux divers besoins gĂ©oscientifiques de la population. Finalement, un dernier aspect des retombĂ©es positives de NATMAP sont tous ces jeunes gĂ©oscientifiques au pays qui poursuivent une carriĂšre dans le domaine et qui ont Ă©tĂ© formĂ©s par leur participation en tant qu’étudiants aux projets de NATMAP
