Résumé :
Purpose. The purpose of the article is to research the peculiarities of creation (updating) of digital topographic maps at the scale of 1:50 000/1:10 000 which would satisfy the requirements for the development of the seamless Topographic Database of the Main State Topographic Map at the scale of 1:50 000. Methodology. The basis for the research is the analysis of the possibilities of applying the theory of databases and knowledge bases, International Standards and specifications and vectorization method. Results. The article examines the peculiarities of creation (updating) digital topographic maps of the scale 1:50000 for the formation of the Main State Topographic Map of Ukraine for the purpose of the creation and maintain the seamless topographic database for national needs, which is located on the Geoportal to ensure the relevance of a single digital topographic basis by topographical monitoring of the territories and for the development of the National Spatial Data Infrastructure in Ukraine. The rules of topological relations between features of the digital topographic maps of the scale 1:50 000 are also defined and given. The peculiarities of providing automated quality control of updated digital topographic maps are investigated. The creation of the seamless Topographic Database of the Main State Topographic Map in the conditions of transfer the cartographic paradigm to geoinformation creates new requirements for the creation (updating) of digital topographic maps of the scale 1:50 000/10 000: creation of spatial schemes, description of the internal design of models and rules of digital description of geospatial features, unification of the features catalog and their attributes, as well as rules of topology between topographic features to ensure topological consistency of geometry in accordance with standards and specifications; creation of the “Validate” software package for checking of created (updated) digital topographic maps at a scale of 1:50 000/10 000 to ensure automated quality control of updated digital topographic maps; creation of new virtual and associated features in the TDB of the Main State Topographic Map. This will increase the intellectual level of geospatial data creation. Scientific novelty and practical significance. The creation of the Main Topographic Map Topographic Database takes into account the use of new virtual and associated features, the use of rules of topological relations between digital topographic map features, providing automated quality control of updated digital topographic maps.

Résumé :
The Antarctic digital topographic database is the outcome of a truly international collaborative project between 11 nations. Data capture was co-ordinated in the UK, under the auspices of the Scientific Committee on Antarctic Research (SCAR), during a two-year period. Over 200 maps, at scales ranging from 1:200 000 to 1:5 000 000, were digitized for the project and reference was made to a similar number of satellite images (mostly Landsat photographic products). Editing and harmonization of the data derived from the different sources has produced a seamless map of Antarctica which has the most up-to-date coastline now available. The topographic database created, to be published on one CD-ROM, will form the foundation for future GIS needs in Antarctic research. Products already derived from the database include digital elevation models and customized maps; the latter can be reproduced by research groups to meet their own mapping needs.

Résumé :
Supervised classification of remotely sensed images is a classical method to update topographic geospatial databases. The task requires training data in the form of image data with known class labels, whose generation is time-consuming. To avoid this problem one can use the labels from the outdated database for training. As some of these labels may be wrong due to changes in land cover, one has to use training techniques that can cope with wrong class labels in the training data. In this paper we adapt a label noise tolerant training technique to the problem of database updating. No labelled data other than the existing database are necessary. The resulting label image and transition matrix between the labels can help to update the database and to detect changes between the two time epochs. Our experiments are based on different test areas, using real images with simulated existing databases. Our results show that this method can indeed detect changes that would remain undetected if label noise were not considered in training.

Résumé :
From the beginning of the twentieth century, topographic maps for the Libyan state carried out by various compilers, where the first mapping was carried out by the Italian Military Geographical Institute, the Soviet Union Military, and the U.S. Army, followed by mapping carried out by the Libyan state from the 1950s to the 2000s. Most of these maps have not been digitized and updated using the techniques of geographic information systems and remote sensing. This paper discusses on the objectives, methodology and results of the Libya Topography Project, “Libya Topo” for updating the previously compiled topographical map at scale, 1:250000. Open spatial data from different platforms (OSM, Logistics Cluster, Landsat 8 satellite imagery, and SRTM data, etc.). Also, POIs extracted from previously compiled topographic and geological maps. Spatial database for each UTM zone created to store the features and raster. As for the cartographic style, the map layout adopted is the style of the U.S. Defense Mapping Agency maps. The results of the project are an update of 121 topographical map sheets using Quantum (GIS), those will be freely available for the interested users on request (e.g., environmentalists, academics, and university students, etc.).

Texte intégral
Résumé :
Theories of socio-cultural change regarding the transition from the Chalcolithic to the Bronze Age in Cyprus have since the nascence of prehistoric archaeology on the island been the subject of lively debate between archaeologists who argue for internal versus external evolution processes. Yet, despite all efforts, a coherent model explaining the evident material culture differences between the two epochs remains elusive, an indication that the current polarization of theories masks inherent complexities of the archaeological record. Moving beyond the internal/external dichotomy, the present thesis argues for one such explanatory model and approaches this notable transition from three distinct and less explored aspects, namely chronology, pottery analysis and topography. Starting with chronology, the thesis assesses previous chronological schemata, examines issues of methodology, performs an in-depth data quality analysis, and, on the basis of the creative dialogue between absolute and relative dating data, proposes a novel chronology for the island. This chronology transcends linearity by adopting cultural period overlaps and differential regional adoption of technologies. Moving to spatial matters, the study disentangles space-time systematics for sites dating from the Middle Chalcolithic to the Philia Phase. In effect, it establishes a ceramic typology for the Chalcolithic that is applicable to the entire island; clarifies and records in a custom-made recording system, dubbed CARMA (Cyprus ARchaeological MAterials Relational Database System), the research history and material assemblages of each site; situates sites in the physical landscape of Cyprus and performs socio-spatial analyses, where the results of pottery analysis are interwoven with the spatial relationships between sites. The last analysis provides positive evidence for cultural uniformity in the Middle Chalcolithic, for the emergence of regional cultures in the Late Chalcolithic and the abandonment of settlements at the beginning of the Philia Phase, and for the co-existence of spatially distinct cultures during the Philia Phase. Lastly, the results of the chronology and spatial studies inform the data synthesis in the final section, where a different narrative of socio-cultural change is developed. This argues for the emergence of divergences already in the Late Chalcolithic, for the co-existence and uneven bi-directional interaction of indigenous and foreign populations during the Philia Phase, and for the development of regionalism in the Early Bronze Age as a result of variable adoption of technologies, entanglement and resistance to cultural identity assimilation.

Résumé :
Cette thèse traite de l'intégration de bases de données topographiques qui consiste à expliciter les relations de correspondance entre bases de données hétérogènes, de sorte à permettre leur utilisation conjointe. L'automatisation de ce processus d'intégration suppose celle de la détection des divers types d'hétérogénéité pouvant intervenir entre les bases de données topographiques à intégrer. Ceci suppose de disposer, pour chacune des bases à intégrer, de connaissances sur leurs contenus respectifs. Ainsi, l'objectif de cette thèse réside dans la formalisation, l'acquisition et l'exploitation des connaissances nécessaires pour la mise en œuvre d'un processus d'intégration virtuelle de bases de données géographiques vectorielles. Une première étape du processus d'intégration de bases de données topographiques consiste à apparier leurs schémas conceptuels. Pour ce faire, nous proposons de nous appuyer sur une source de connaissances particulière : les spécifications des bases de données topographiques. Celles-ci sont tout d'abord mises à profit pour la création d'une ontologie du domaine de la topographie. Cette ontologie est utilisée comme ontologie de support, dans le cadre d'une première approche d'appariement de schémas de bases de données topographiques, fondée sur des techniques d'appariement terminologiques et structurelles. Une seconde approche, inspirée des techniques d'appariement fondées sur la sémantique, met en œuvre cette ontologie pour la représentation des connaissances sur les règles de sélection et de représentation géométrique des entités géographiques issues des spécifications dans le langage OWL 2, et leur exploitation par un système de raisonnement
This PhD thesis deals with topographic databases integration. This process aims at facilitating the use of several heterogeneous databases by making the relationships between them explicit. To automatically achieve databases integration, several aspects of data heterogeneity must be detected and solved. Identifying heterogeneities between topographic databases implies comparing some knowledge about their respective contents. Therefore, we propose to formalise and acquire this knowledge and to use it for topographic databases integration. Our work focuses on the specific problem of topographic databases schema matching, as a first step in an integration application. To reach this goal, we propose to use a specific knowledge source, namely the databases specifications, which describe the data implementing rules. Firstly, they are used as the main resource for the knowledge acquisition process in an ontology learning application. As a first approach for schema matching, the domain ontology created from the texts of IGN's databases specifications is used as a background knowledge source in a schema matching application based on terminological and structural matching techniques. In a second approach, this ontology is used to support the representation, in the OWL 2 language, of topographic entities selection and geometry capture rules described in the databases specifications. This knowledge is then used by a reasoner in a semantic-based schema matching application

Abstract The Topographic in scale of 1:5000 to 1:50000 have been established positively since 1965 in Taiwan. In these years, the large scale topographic were essential because of the county governments developed the local constructions. And that the quality of topographic data affects the plan execution, policy decision and tactic results. So during the topographic building time slice, the topographic data quality of examination is vital. Depending on the above reasons, this study confer with the quality examination standard model for GIS topographic database and then the results can be treated as the basis of quality examination for GIS topographic database. First of all, this research concludes six elements that affect the quality of spatial database as follows: (1) database field format, (2) database completeness, (3) database logical consistency, (4) map-alignment inside database, (5) the relationship of map and attribute data inside database, (6) attribute data accuracy. This study takes the six elements as the basis to design the standard quality examination method for GIS topographic database. Next step of this study, considers the spatial characteristic of GIS database, accordingly the original data lie in spatial distribution. Therefore the density of the spatial data distribution is also a consideration. This study integrated the traditional sampling method and data distributive characteristic to choose the proper method for the examination of GIS topographic database. The numbers of exam samples are depending upon population distributive density percent in the Urban-Land-Use-Map. Finally, this research investigates at actual data samples to examine the data spatial accuracy and attribute correctness. This study used the ANOVA to discuss the difference among the 5%, 7%, and 10% samples, and the result is almost the same ( α＝0.05，confidence level ＝ 95％). This result shows that we can use the 5% samples to achieve the goal of quality examination for GIS topographic database.

Résumé :
The research problem undertaken in the study is the occurrence of dispersed and concentrated built-up (in particular residential) area patterns caused by suburbanisation processes in a large urban agglomeration, on the example of the Warsaw metropolitan area. The research concerned the period after 1989, when the political and economic transformation in Poland began. The historical and contemporary socio-economic conditions of suburbanization and urban sprawl are described, which have the features of a spontaneous, chaotic dispersion, quite different than in Western countries. It is partly to blame for faulty spatial planning. The succession of urban development into rural areas is subordinated to the factors of the construction market. In the empirical part of the analysis, topographic data on all buildings in the urban agglomeration and databases on land use derived from satellite images were used to investigate settlement changes. A multidimensional study was carried out relating to various spatial scales, types of spatial relations and territorial units. Measures of spatial concentration of point patterns as well as landscape metrics were used for this purpose. The indicators used were subject to critical methodological evaluation afterwards. The study was performed in several temporal cross-sections. The locations of new development in agricultural, forest and wasteland areas have been identified. Finally, recommendations for the implementation of appropriate spatial policy and improvement of the spatial order in the Warsaw agglomeration were formulated

Résumé :
Both this, article II and another one, article I, titled “Geometric Quality In Geographic Information” published in this encyclopedia propose the theoretical aspects of the method to evaluate the geometric integrity of Digital Elevation Models obtained by different techniques and therefore, different stochastic hypotheses are considered. In the article I we considerer the classical topographic or aerial photogrammetry stereo images method (included ASTER or SPOT images) and we assume consistent stochastic hypotheses. In this Article II we consider IFSAR techniques and the stochastic hypotheses are specific according to the particular geometry involved in this technique.

Résumé :
Both this article, referred to as Article I, and another one, Article II, entitled “Geometric Quality in Geographic Information IFSAR DEM Control”, published in this encyclopedia propose a method to evaluate the geometric integrity of Digital Elevation Models obtained by different techniques. Therefore, the theoretical aspect of the method to evaluate the geometric integrity and different stochastic hypotheses will be presented in both of them. Herein, we consider the classical topographic or aerial photogrammetry stereo images method (included ASTER or SPOT images) and we assume consistent stochastic hypotheses. In the Article II we consider Interferometry SAR (IFSAR) techniques and the stochastic hypotheses are specific according to the particular geometry involved in this technique.

Résumé :
The issue of city walkability is nowadays a theme in evidence. The chapter proposes a two-level reasoning. At the city level, the goal is to recognize the parts where actions aimed at improving walkability can be more effective. The second level is more detailed: lacking pedestrian paths' specific graphs, the urban space is modeled through a raster with 1x1 m. cells. Considering a series of criteria, an impedance has been assigned to each cell (i.e., the cost of travelling the cell on foot). This approach is applied to the city of Torino (Italy), but it is largely generalizable. To calculate this impedance, inter alia, the Torino geo-topographic database was used. The elaborations described in this chapter are seen as an aid to stakeholders to reason on city walkability and to compare different points of view in an explicit and articulated way.
