[Termes IGN] spécification de produitRésumé : (Auteur) The Geospatial Information Authority of Japan [formerly the Geographical Survey Institute of Japan] (GSI) began the publication of Digital Maps (Basic Geospatial Information) on July 30, 2012 as a survey result of vector data mainly composed of 'Digital Japan Basic Maps', the data sets of maximum-scale geospatial data covering the whole of Japan. Since Digital Maps (Basic Geospatial Information) are basically provided online, they can offer new information on a daily basis as a result of surveys that reflect major changes to the land, compared to traditional survey results. However, it is necessary to use special software in order to utilize Digital Maps (Basic Geospatial Information) as map data. So the online publishing of 'Digital Topographic Map 25000' (hereinafter referred to as 'Digital Topographic Map') began on August 30 2012 so that map information that immediately reflects major changes to the land can be used more conveniently as a survey result in a raster image file format on a 1:25,000 scale level. Using this Digital Topographic Map, maps can be created that optimize the benefits of online publication by selecting the display range and size, as well as some display colors of map symbols and representations according to the intended use of the purchasers. Another feature is the ability to always provide the latest version of map images, as the images are generated from the Digital Japan Basic Map of Japan database as soon as the order is received from the purchaser, rather than from archived images. This paper presents the concept and specifications of the 'Digital Topographic Map' as the new survey result, and an overview of the content of the development of the system being provided.

[Termes IGN] traitement de donnéesRésumé : (Auteur) Lidar systems have been proven as a cost-effective tool for the collection of high density and accurate point cloud over physical surfaces. The collected point cloud does not exhibit homogenous point distribution due to the characteristics of the scanning system and/or the physical properties of the scanned surfaces. In order to effectively process the lidar point clouds, local point density variations should be quantified and taken into account for the definition of processing parameters. In this paper, new approaches are presented for the estimation of local point density indices while considering the 3D relationship among lidar points, the physical properties of the reflecting surfaces, and the noise level in the datasets collected by different laser scanners. The impact of considering the estimated local point density variations on the quality of lidar data segmentation results is then investigated by performing a quality control procedure. Quantitative evaluation of segmentation results highlights the efficacy of utilizing the estimated local point density indices for the derivation of more accurate segmentation.

[Termes IGN] visualisationRésumé : (auteur) Nowadays, a huge amount of geodata is available. In this context, efficient discovery and retrieval of geographic data is a key issue to assess their fitness for use and optimal reuse. Such processes are mainly based on metadata. Over the last decade, standardization efforts have been made by the International Standard Organization (ISO) and the Open Geospatial Consortium (OGC) in the field of syntactic interoperability between geographic information components. Among existing standards, ISO-19115 standard provides an abstract specification of metadata for geospatial data discovery and exploration, ISO-19110 defines feature catalogues, and ISO-19131 defines data product specifications. Yet, information provided by these standardized metadata is not always formalized enough to enable efficient discovery, understanding and comparison of available datasets. Notably, information regarding geodata capture rules can be represented only through free text into the standard metadata (ISO 19131).More generally, geospatial database capture specifications are a very complex but very rich source of knowledge about geospatial data. They could be used with benefits in geospatial data discovery process if they would be represented in a more formal way than in existing ISO standards. In this context, we propose a model to formalize geospatial databases capture specifications. Firstly, we extend existing standards to represent information that was insufficiently formalized. Second, we propose an OWL representation of our global model. This ontological approach enables to overcome the limitations related to string-based queries and to provide efficient access to data capture information. Finally, we implement this model as a Web application allowing users to discover the available geospatial data and to access to their specifications through a user-friendly interface.

[Termes IGN] spécificationRésumé : (Auteur) We analyze the state of the art of content-based retrieval in Earth observation image archives focusing on complete systems showing promise for operational implementation. The different paradigms at the basis of the main system families are introduced. The approaches taken are considered, focusing in particular on the phases after primitive feature extraction. The solutions envisaged for the issues related to feature simplification and synthesis, indexing, semantic labeling are reviewed. The methodologies for query specification and execution are evaluated. Conclusions are drawn on the state of published research in Earth observation (EO) mining.

[Termes IGN] Web Map ServiceRésumé : (Auteur) Internet-based Geographical Information Services (GIServices) have exploded in depth and variety over the past few years. More and more academic institutions, private companies, and even individuals publish their own geographical information resources in the form of GIServices on the Internet. In today's resource-rich environment, fast and accurate service discovery is a significant problem for industry and academia, as well as regular users. To solve this problem, researchers introduced Service-Oriented Architecture (SOA) to the domain of GIServices. Being the core of SOA, a registry catalogue implements message exchange services. But current catalog service mechanisms lack the capability to search services, to monitor and to provide accurate descriptions for quality of service in an active manner. Therefore, current catalogue services are not able to overcome problems such as limited registered resources, inaccurate registration information and the uncertainty of service status in various geospatial applications. A catalogue framework for GIServices is proposed that effectively integrates the Quality of GIServices (QoGIService) theory, as well as service crawling/search and dynamic monitoring techniques. A prototype application focused on Web Map Services (WMS) was established that mitigated the abovementioned problems through active service evaluation and real-time quality monitoring mechanisms.
