[Termes IGN] service webRésumé : (auteur) When an Inspire infrastructure is designed, many issues are raised to make sure that the infrastructure will be interoperable, useful and convenient to maintain, many issues that go beyond Inspire requirements. Building persistent identifiers is one of these issues. The path to URI (Unique Resource Identifiers) has required several steps. The first step was at the general French level. It was necessary to define national recommendations to make sure the national infrastructure would be working. Based on the ARE3NA study about PIDs, guidelines have been designed. This document has two aspects: A pedagogic aspect first: Defining PIDs seemed a huge amount of work for many data providers. The guidelines contain an overview of existing technologies, their advantages/disadvantages and on which criteria you could pick one or the other. A minimum set of requirements: Some data providers had already defined PID so the goal was to minimize the impact of these guidelines. It appeared that the moot point in the Inspire infrastructure was to be able to make a link between dataset metadata and the service that serves this dataset. Thus, the main recommendation has been to recommend a resolvable data identifier, pointing at least to the dataset metadata. Once these guidelines have been published, IGN France has decided to work on a new URI policy. This definition was done in a context where a new database product was being designed. We had the experience of the Datalift research project around linked data and of IGN register. The choice was quickly made to use persistent URLs as identifiers. The work was carried out in a group gathering people from different backgrounds: production, research, standardization, Inspire and developments. The first step was to define on which kind of resources an identifier had to be defined (objects, metadata, CRS, documents, etc). Then for each kind of template a URL pattern was designed. This pattern had to take into account existing identifiers, potential use cases and best practices from other organisms and from the datalift project. Future works will consist in defining on which kind of resources these URLs will point and developing a redirection tool, able to point to these resources. It is still a work progress and there is a lot to do to be able to produce linked data but this first approach to sensitize producers with a first reasonable step.

[Termes IGN] Web Feature ServiceRésumé : (auteur) Urban planning data are produced and diffused by municipalities or state services. French strategy to reach INSPIRE requirements consists in two steps. First, all the data will be digitized by producers by 2020 using national CNIG standard. Then the data gathered on the national urban planning website will be processed in order to fulfil INSPIRE data model. This gathering will be made manually or automatically, through web services. Two types of services are foreseen: OGC WFS and ATOM feed.
Inspire download service technical guidelines based on WFS were not sufficient to reach expected level of interoperability. Another profile has been defined based on OGC WFS standard. This profile is compliant with the Inspire download service direct access conformance class. Some requirements have been added on the content of GetCapabilities response document: keywords, abstract, profile, metadataUrl. Some constraints have been added at the service level: Two formats have to be supported (GML and SHAPE-ZIP, to be compliant both with OGC WFS standard and the original national CNIG standard), several coordinates systems have to be provided (for France and its overseas territories) in addition to European reference systems to be compliant with national requirements. Additional requirements have been added to describe more precisely published data. As the national CNIG standard is based on a shapefile implementation, a GML encoding of this standard has been provided (as a GML schema), as well as the list of features types to be provided. As a huge amount of data is foreseen, it is not an option to harvest data on a regular basis so an update system has been set up. The mechanism is based on the updateSequence attribute of the GetCapabilities document. A filter is then done based on identifiers to find updated objects.
This profile is being implemented so it is regularly amended based on comments/feedbacks. The goal will be to have a profile able to provide the level of interoperability to make the French urban planning infrastructure work. This infrastructure will also be the INSPIRE-compliant infrastructure offering data harmonized at a national level. This experience could be useful to other member states willing to set up such an infrastructure, even in other domains. Indeed, this approach enforces Inspire technical guidelines as a common starting point on which specific/national requirements can be built on.Numéro de notice : C2016-006 Affiliation des auteurs : IGN (2012-2019) Thématique : GEOMATIQUE Nature : Communication nature-HAL : ComSansActesPubliés-Unpublished DOI : sans Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=82186 Documents numériques

[Termes IGN] utilisation du solRésumé : (auteur) What landscapes best represent the land uses and land covers (LU/LC) of the continental United States? Would the set include a cornfield? A forest? A backyard? Combining principles of landscape ecology and computer science, we identified a small set of “exemplar landscapes”, representing distinct LU/LC pattern types of the conterminous US. We first partitioned the 1992 US National Land Cover Dataset into 193 705 landscapes, and quantified patterns with standard measures of LU/LC composition and configuration. Using the values to estimate similarity of LU/LC patterns between landscapes, we applied an algorithm developed to find representatives in large sets. In the resulting 17‐member set of exemplar landscapes, patterns created and managed by human activity are by far the most evident features. This set of representatives summarizes the nation's LU/LC, demonstrating the degree to which human‐influenced patterns dominate: aggregations of rectangular fields, farmlands within cleared forests, shrublands/pasture, and suburbs. The algorithm's selection of an exemplar for each group may have other ecological applications when an objectively determined subset of representative items is needed.

Ce stage a été réalisé du 1er juillet 2008 au 31 octobre 2008. Il consistait à réaliser un outil d'analyse pour le système SIEL-BUS. Ce système permet de localiser les bus à chaque instant pour, par exemple en tirer une information voyageur plus précise. Le Recorder permet de faire une analyse statistique a posteriori de ces informations pour estimer la qualité de localisation, recenser les alarmes qui ont eu lieu, vérifier le respect des itinéraires ... Le Recorder a déjà été développé en plusieurs versions qui ne sont plus utilisées actuellement à cause de problèmes de licences et d'obsolescence. Cette version est donc entièrement basée sur des logiciels libres. Le Recorder est constitué de deux entités qui fonctionnent en réseau. La première forme un noyau principal, qui réalise l'ensemble des calculs et qui est hébergé sur un serveur. La seconde entité est un exécutable qui permet aux utilisateurs d'accéder à une interface graphique à partir de leur poste, quel qu'il soit. Cette interface leur permet de commander au serveur toutes les actions d'analyses et d'enregistrement souhaitées par l'utilisateur. Note de contenu : 1. Présentation du projet
