[Termes IGN] système d'information géographiqueRésumé : (Auteur) The use of remote sensing data with other ancillary data in a geographic information system (GIS) environment is useful to delineate groundwater potential zonation map of Ken-Betwa river linking area of Bundelkhand. Various themes of information such as geomorphology, land use/land cover, lineament extracted from digital processing of Landsat (ETM+) satellite data of the year 2005 and drainage map were extracted from survey of India topographic sheets, and elevation, slope data were generated from shuttle radar topography mission (SRTM) digital elevation model (DEM). These themes were overlaid to generate groundwater potential zonation (GWPZ) map of the area. The final map of the area shows different zones of groundwater prospects, viz., good (5.22% of the area), moderate (65.83% of the area) poor (15.31% of the area) and very poor (13.64% of area).

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) The process of topographic map production at the national mapping agencies is undergoing steady change. The pressure to reduce production cost in particular hassled to the development and use of new approaches. Traditionally, separate datasets and models have been used to produce topographic maps of different scales and even the sources of data often differ. As a consequence, the derived datasets on different scales are usually inconsistent and thus cannot be updated in a common process. With the transition to GIS-based cartography, these disadvantages will be overcome. The research and development presented here have been carried out within an application-oriented research project of the University of Zurich in cooperation with the company Axes Systems. The focus has been on improving automated generalisation for topographic map production. A multiple representation database with extended linkage information was first implemented. These so-called vertical relations enable the storage of meta-information, which is needed to make the generalisations used during incremental updates. Second, a data model of horizontal relations was developed, to model contextual information explicitly. Examples of applications are the subdivision and partition of datasets, and the modelling of feature groups. Third, a service-oriented architecture was established, enabling a platform-independent development and the provision of generalisation functionality. In addition, an embedded workflow management system was introduced, consisting of a workflow editor and workflow engine, to support the interactive configuration of the generalisation process and the automated execution of generalisation services.

[Termes IGN] WebSIGRésumé : (Auteur) Geocoding is an uncertain process that associates an address or a place name with geographic coordinates. Traditionally, geocoding is performed locally on a stand-alone computer with the geocoding tools usually bundled in GIS software packages. The use of such tools requires skillful operators who know about the issues of geocoding, that is, reference databases and complicated geocoding interpolation techniques. These days, with the advancement in the Internet and Web services technologies, online geocoding provides its functionality to the Internet users with ease; thus, they are often unaware of such issues. With an increasing number of online geocoding services, which differ in their reference databases, the geocoding algorithms, and the strategy for dealing with inputs and outputs, it is crucial for the service requestors to realize the quality of the geocoded results of each service before choosing one for their applications. This is primarily because any errors associated with the geocoded addresses will be propagated to subsequent decisions, activities, modeling, and analysis. This article examines the quality of five online geocoding services: Geocoder.us, Google, MapPoint, MapQuest, and Yahoo!. The quality of each geocoding service is evaluated with three metrics: match rate, positional accuracy, and similarity. A set of addresses from the US Environmental Protection Agency (EPA) database were used as a baseline. The results were statistically analyzed with respect to different location characteristics. The outcome of this study reveals the differences among the online geocoding services on the quality of their geocoding results and it can be used as a general guideline for selecting a suitable service that matches an application's needs.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Both Geographic Information Systems and Information Retrieval have been very active research fields in the last decades. Lately, a new research field called Geographic Information Retrieval has appeared from the intersection of these two fields. The main goal of this field is to define index structures and techniques to efficiently store and retrieve documents using both the text and the geographic references contained within the text. We present in this paper two contributions to this research field. First, we propose a new index structure that combines an inverted index and a spatial index based on an ontology of geographic space. This structure improves the query capabilities of other proposals. Then, we describe the architecture of a system for geographic information retrieval that defines a workflow for the extraction of the geographic references in documents. The architecture also uses the index structure that we propose to solve pure spatial and textual queries as well as hybrid queries that combine both a textual and a spatial component. Furthermore, query expansion can be performed on geographic references because the index structure is based in an ontology.
