La mise en œuvre d’indicateurs agri-environnementaux au niveau territorial se heurte à un obstacle opérationnel qui est la phase d’acquisition des données sur les pratiques, la description des sols, la végétation voire des données climatiques et ceci que ce soit à des résolutions fines (parcelles, exploitation) ou sur de grandes étendues (département, région ou pays). Le recours à des données satellitaires constitue une piste majeure pour lever ce verrou, notamment avec l’arrivée à partir de 2014 d’une nouvelle génération de satellites à haute résolution d’observation de la terre : les Sentinel. Après un bref état de l’art des possibilités offertes par ces nouveaux satellites, l’article présente les avancées sur le développement d’indicateurs agri-environnementaux calculables au moyen de la télédétection. Un focus est mis sur trois indicateurs dans le cadre du projet H2020 NIVA: bilan carbone, risque de lixiviation des nitrates et biodiversité.

Reusing geo-data already produced by members to monitor activities at the level of the country or region in order to perform monitoring and planning at the global level of Europe is a different but related issue. It is a strategy to achieve more consistency and trust between the different levels where environmental activities and policies are monitored. This strategy has led the European Commission to issue the INSPIRE directive–Infrastructure for Spatial Information in Europe- ; national public authorities should make their data reusable for Europe [European Parliament 2007][Video 1]. Reusing at the level of Europe national data is not straight forward. Even though we share a common European physical territory, especially in the domain of environment where many phenomena do not stop at borders, each country has its own specific way to design data about ground water, transport networks, population, landuse and air temperature. The European digital territory also has its boundaries. The ‘INSPIRE extensions’ workshop was organized to foster exchanges between organizations in charge of implementing INSPIRE, with a focus on the topic of extending INSPIRE Data Specifications, to share their experiences, improve each one’s knowledge and also the scalability of local initiatives. It was co-organised by EuroGeographics Knowledge Exchange Network on INSPIRE (aka KEN INSPIRE), EuroSDR Commission 4 (focused on information usage) and Geonovum, a public organization who is coordinating the Dutch National Spatial Data Infrastructure (NSDI) supported by the Dutch Cadaster and the Geological Survey of the Netherlands. Complementary to the minutes dedicated to the KEN INSPIRE community, this report wishes to be more pedagogic to reach out an audience –scientists or developers- who may not be familiar enough with INSPIRE issues and problems but could find INSPIRE as a possible application domain for its scientific or technological field and, in the future, be willing to contribute to the progress of INSPIRE. The two first sections summarise the motivation of INSPIRE and the reasons for designing INSPIRE Data Extensions. The section after presents approaches adopted by practitioners: inheritance on the one hand and adaptation on the other. The subsequent sections tackle issues related to INSPIRE implementation in general and not limited to Data extension. All presentations of the workshop together with the minutes are available on the workshop website: https://eurogeographics.org/calendar-event/workshop-on-inspire-extension-june-2017/ Numéro de notice : 25848 Affiliation des auteurs : LASTIG COGIT+Ext (2012-2019) Autre URL associée : vers HAL Thématique : GEOMATIQUE Nature : Rapport sur congrès nature-HAL : Rapport DOI : sans En ligne : http://www.eurosdr.net/publications Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=95329

The difficult way towards Land cover and land use data harmonization across scales, space and time in Europe / Dominique Laurent (2019)

This is the domain of land cover and land use data design which receives attention from a vast community, from raw data providers (satellite imagery, in situ data) to data curators and integrators as well as users. One of the first attempts to harmonize Land Cover and Land Use data has been the INSPIRE Directive (voted in 2007) that aims to provide the legal framework for achieving a European Spatial Data Infrastructure where the Commission could reuse national data used by members for their national policies. Among its Implementing Rules, interoperability is addressed through the definition of common data models for land cover and for land use information. INSPIRE being based on existing data, these models have been defined to be quite flexible. On the one hand, this European legal context and the new technical opportunities may push data producers to design new land cover and land use products, with for example more concern for European reusability of national products. On the other hand, land cover and land use data are often used to compute evolution indicators, which requires stable enough or at least comparable specifications; which rather push data providers to stick to former data specification. More recently, UN-GGIM: Europe (United Nations initiative on Global Geographic Information Management) has set up a Working Group on spatial data the most useful to analyze, achieve or monitor the Sustainable Development Goals, called core data. This group defines priorities for the production of new data or the enhancement of existing one. Land Cover and Land Use are identified as core data themes. The EuroGeographics INSPIRE KEN (Knowledge Exchange Network) and EuroSDR organised a workshop in November 2017 on this topic: how to make the most of available technologies (in terms of precision, accuracy and cost) as well as how to achieve products comparability and reusability across scales, space and time. Main conclusion was that quite diverse national practices must be accounted, though the concept of separating land cover and land use was widely adopted. Besides, attendees express the need to connect to new communities: deep learning to cope with big data, and communities studying the surveyed phenomena to integrate more domain knowledge in land cover and land use surveying process. Last, meta-models like EAGLE supporting the comparison of classifications were recognized as a key SDI component. The presentation will remind why data harmonization is useful, it will provide an overview of what has been achieved and explain the remaining difficulties.

Challenges Implementing INSPIRE coverage data [diaporama] / Dominique Laurent (2016)

Format : pdf Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] données massives [Termes IGN] Europe (géographie politique) [Termes IGN] harmonisation des données [Termes IGN] INSPIRE [Termes IGN] orthoimage [Termes IGN] serveur [Termes IGN] spécification de contenu Résumé : (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.
