[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] urbanismeRésumé : (auteur) Context: why do we need a national website and infrastructure ? Until now, when some professional or citizen need to access urbanistic rules on a local area, he has to move to the competent authority head office. In 2020, all the urbanistic rules will be available on www.geoportail- urbanisme.gouv.fr. This website contributes to three goals:
o Apply INSPIRE directive;
o Facilitate urbanism stakeholders jobs;
o Simplify access by citizens to the urbanistic rules and maps;
Indeed urbanistic data are in the scope of INSPIRE (at least Annex I theme 8 and Annex III theme 4 and 11).
Digitalizing and gathering urbanistic data: Urbanistic data are produced and diffused by municipalities or state services. Most of the time these documents and maps are paper based. French strategy to reach INSPIRE requirements consists in two steps. First all the data will be digitized by producers between 2016 and 2020 using national CNIG standard. Then the data gathered on the national urbanism website will be processed in order to fulfil INSPIRE data model. The national CNIG standard specification are close to INSPIRE data model but much more easy to understand from local actors points of view. The first version of this standard was published in 2013 and a second one was ublished in 2014. Accessing urbanistic data: Further than the website, the infrastructure is INSPIRE compliant since view service, download service and discovery services are settled. Moreover data can be uploaded in the infrastructure by file upload or directly using download services from other infrastructure. Costs and expected benefits: Citizens and professional access to urbanistic rules and maps will be facilitated by this website. For data producers, such as municipality, digitalization costs 500€ on average per document. Considering that each paper based version costs 100€, the return on investment should be reached fast. Furthermore, data updating costs will be decreased a lot on a digitalized version than on a paper based. Last but not least data model transformation to reach INSPIRE requirements will be done only once thanks to national CNIG standard. This allows mutualisation of skills and costs.Numéro de notice : C2016-004 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=82184 Documents numériques

[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] orthoimageRésumé : (Auteur) Avec Géoportail, le territoire français possède l’un des meilleurs outils d’information géographique qui soient. Et pourtant, beaucoup trop de Français vont sur Google Maps/Earth, en ignorant les trésors de notre site... même les personnels d’administrations qui sont en partenariat avec l’IGN... Ne parlons pas des randonneurs, alpinistes, spéléologues ou nombreux autres utilisateurs issus de la civilisation de loisirs. Il m’a paru utile de faire une synthèse de tous les documents, articles, communications ayant un rapport avec Géoportail et de montrer l’immense supériorité de cet outil d’information géographique en ce qui concerne notre territoire.

[Termes IGN] web sémantiqueRésumé : (auteur) Geoportals provide integrated access to geospatial resources, and enable both authorities and the general public to contribute and share data and services. An essential goal of geoportals is to facilitate the discovery of the available resources. Such a process relies heavily on the quality of metadata. While multiple metadata standards have been established, data contributers may adopt different standards when sharing their data via the same geoportal. This is especially the case for user-generated content where various terms and topics can be introduced to describe similar datasets. While this heterogeneity provides a wealth of perspectives, it also complicates resource discovery. With the fast development of the Semantic Web technologies, there is a rise of Linked-Data-driven portals. Although these novel portals open up new ways to organize metadata and retrieve resources, they lack effective semantic search methods. This article addresses the two challenges discussed above, namely the topic heterogeneity brought by multiple metadata standards and the lack of established semantic search in Linked-Data-driven geoportals. To harmonize the metadata topics, we employ a natural language processing method, namely Labeled Latent Dirichlet Allocation (LLDA), and train it using standardized metadata from Data.gov. With respect to semantic search, we construct thematic and geographic matching features from the textual metadata descriptions, and train a regression model via a human participants experiment. We evaluate our methods by examining their performances in addressing the two issues. Finally, we implement a semantics-enabled and Linked-Data-driven prototypical geoportal using a sample dataset from Esri's ArcGIS Online.
