[Termes descripteurs IGN] spécification de contenuRésumé : (auteur) The INSPIRE KEN (Knowledge Exchange Network) of EuroGeographics and the INSPIRE Thematic Cluster on themes Elevation and Ortho-imagery organized in September 2015 a workshop dedicated to the implementation of coverage data and on relevant download services, mainly focused on themes orthoimagery and Elevation. The proposed presentation aims to expose the main learnings of this workshop and of the subsequent activities that followed the event. On the positive side, Web Coverage Services (WCS) are, at least in theory, powerful tools to deliver and better harmonize the data expected by INSPIRE. The workshop was also an opportunity to exchange experiences about implementation of coverage data and services: whereas NMCAs are beginners, other communities, such as hydrographic or meteorological ones are quite more advanced. On the negative side, there are remaining issues that might prevent data producers to transform quickly their coverage data and that, in opposite, might encourage them to expect clarifications and wait until the 2020 dead-line. The first point is related to the INSPIRE regulation that is not yet complete (Implementing Rule about WCS as a download service is still under preparation) or might evolve in the future (e.g. due to the standard evolution from GMLCOV to CIS v1.1). The second point is related to the state-of-play of technologies: it is unsure that the current WCS servers and client applications are mature and scalable enough to deal with huge volumes of coverage data. A typical issue for data producers is to decide on the approach to provide coverage data of a vast territory in a digestible way for the download services. The third point is related to the INSPIRE data specifications that have brought at conceptual level some extensions to the coverage standards that are supposed to be useful to satisfy relevant use cases, but are ignored by existing WCS implementations; these extensions might bring in practice possible duplicities or even inconsistencies. There are for instance several ways to document coverage metadata or the coverage extent that often bring to confusion among implementers. Summing up, the future publication of the technical guidelines drafted by MIG-T MIWP-7b subgroup
on WCS (related to implementation and provision of INSPIRE coverage data using WCS download services) and the imminent adoption of the CIS v1.1 standard by OGC give the floor to updating the related INSPIRE data specifications in the short term.Numéro de notice : C2016-008 Thématique : GEOMATIQUE Nature : Communication nature-HAL : ComSansActesPubliés-Unpublished DOI : sans Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=82188 Documents numériques

[Termes descripteurs IGN] projetRésumé : (auteur) The workshop aims to explain how the ELF project articulates with INSPIRE, presenting these interrelations as a modern love story! Coming from the European Commission family, INSPIRE was a handsome and clever guy; though young, he already performed significant achievements by setting up the legal framework for the European Spatial Data Infrastructure. However, he felt alone and needed some help to transform this legal framework into an operational platform delivering harmonized data. Coming from the EuroGeographics family, the ELF initiative was also young but with similar ambitions as INSPIRE and with some practical achievements coming from a previous project (ESDIN). Of course, this common viewpoint brought them closer and they fell in love very quickly! In a classical tale, it would be the end of the love story but in a modern tale, the two protagonists have to decide about how to manage their respective assets and how to raise their children … all topics that may be cause of fruitful cooperation but also of dispute! For instance, do the ELF specifications bring any improvement to the beautiful INSPIRE house or are proposing a competitive place of living? How difficult or easy was the birth of the so expected operational services children? What about the ELF products and ELF licences? Should we consider them as the common children of ELF and INSPIRE (as built on INSPIRE) or is INSPIRE just their stepfather (as no equivalent in INSPIRE)? The INSPIRE GeoPortal and the ELF platforms look like just half-brothers, not sharing the same objectives and not being based on same technologies? Nevertheless, do they live quietly together or are they always fighting? Is it the same case for the ELF and INSPIRE tools, do they address the same issues (and might duplicate) or are they complementary? Last but not least, what is the future of this love story? Will the promising children grow in beauty, strength, efficiency… or will they just become exasperating teen-agers? Will they get new children? How will the children’s financial future be secured? Will the European Commission and EuroGeographics families provide some financial help? Might they divorce or in opposite will they get officially married? Our story tellers will explain in detail how our very active protagonists have organised their modern family life, struggling to make their various achievements live in a (relatively) harmonious way and how their future might look like.

[Termes descripteurs IGN] spécification de contenuRésumé : (auteur) The INSPIRE Directive has set up the legal and technical framework for harmonising the existing data related to the themes of annexes I, II and III. INSPIRE specifications provide common data models that ensure the first step towards interoperability; However, as most of the features and attributes of these data models are “voidable”, it is likely that different INSPIRE datasets will not be homogeneous in their content and level of detail. This background led the UN-GGIM: Europe Regional Committee to setup in 2014 the Work Group A (WG A) on Core Data to deal with core data specifications and quality, production issues, funding and data availability. Core data specifications will complement the INSPIRE initiative by defining the priorities on the core content that will be recommended to be made available, either by harmonising existing data when practicable or by producing new data when necessary. The first phase of WG A has been to define core data themes among the 34 INSPIRE themes. To carry out this selection of core data themes, WG A applied a methodology consisting mainly in a bottomup approach based on identifying user needs, with focus on the Sustainable Development Goals (SDGs) agreed by Member States in the framework of the United Nations 2030 Agenda for Sustainable Development. Therefore, defining the core data scope has consisted in selecting the INSPIRE themes that are the most widely required by the SDGs. As a result, 13 INSPIRE themes have been considered as core:
- INSPIRE Annex I: Geographical Names; Administrative Units; Addresses; Cadastral Parcels; Transport Networks; Hydrography.
- INSPIRE Annex II: Elevation; Land Cover; Orthoimagery.
- INSPIRE Annex III: Statistical units; Buildings; Area management/restriction/regulation and
reporting units; Land use.
The next phase of WG A will be, for each selected theme, to decide on the technical specifications that should ensure homogeneous data on whole geographic Europe, from geometric point of view (e.g. homogeneous levels of detail) and from semantic point of view (e.g. mandatory content for the selected feature types and attributes). These future specifications should be profiles of the INSPIRE ones, they are expected to be both less demanding regarding the number of filled feature types and attributes but more demanding regarding the quality aspects. In addition, the UN-GGIM WG A work might feed other UN-GGIM initiatives at world level, such as the global Working Group on fundamental geospatial data themes.Numéro de notice : C2016-007 Thématique : GEOMATIQUE Nature : Communication nature-HAL : ComSansActesPubliés-Unpublished DOI : sans Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=82187 Documents numériques

[Termes descripteurs IGN] Styled Layer DescriptorRésumé : (auteur) The European Location Framework (ELF) project aims to provide harmonised, INSPIRE-based data from NMCAs. Based on this harmonised data, ELF has designed several view products using SLD standard, namely the Administrative BaseMap, the Topographic BaseMap and the Cadastral Index Map. In addition, ELF has transformed the INSPIRE documentation about portrayal into operational Style Layer Descriptor (SLD) files. The SLD standard is composed of two parts: the filter that defines the feature type and selection criteria to be used in the layer and the portrayal rules themselves (symbol, applicable scales, positioning rules for labels). When designing a view product, the first phase is obviously to design the SLD file. First difficulty was the complex data model of some INSPIRE themes (especially Transport Network), considered as not convenient for the selection criteria aiming to define the layers: choice was made to use simplified models derived from the INSPIRE. Then, it should be decided how to design the SLD file; e.g. for the Administrative BaseMap, the selection criteria and portrayal rules were elaborated using QGIS and then exported as SLD but some manual work remained to deal with the labels. The ELF project has developed an SLD editor tool that facilitates the modification of existing SLD files- regarding the portrayal rules. The second phase is the use of SLD when implementing view services. In general, the SLD standard has been a very useful tool in the ELF context, especially for the view products using a decentralised production process: the Topographic BaseMap and the Cadastral Index Map are based on national WMS set up by various NMCAs using different implementation solutions, such as Map Server, GeoServer, ArcGIS server, Intergraph WebMapServer. Globally, the use of SLD standard has enabled data providers to get (relatively) homogeneous rendering in a multiple actors, multiple tools -and multiple versions context. However, some difficulties remain: for instance, the SLD file has to be adapted for some implementation solutions, e.g. to be transformed into MapFiles for Map Server. In addition, it is difficult to fully specify the label process within the SLD and significant part of the work is up to the implementation solution. In conclusion, the SLD standard has really empowered ELF to design its view products; it has proved to be good enough regarding the (simple) symbols to be applied to features but there remain some progress to be done regarding the label process.
