Most of these geospatial data are available as structured and semi‐structured datasets, and often use distinct data models, are encoded using ad‐hoc vocabularies, and sometimes are being published in non‐standard formats. Hence, these data are isolated within silos and cannot be shared and integrated across organizations and communities. Spatial Data Infrastructures (SDIs) have emerged and contributed to significantly enhance data discovery and accessibility based on OGC (Open Geospatial Consortium) Web services. However, finding, accessing, and using data disseminated through SDIs are still difficult for non‐expert users. Overcoming the current geospatial data challenges involves adopting the best practices to expose, share, and integrate data on the Web, that is, Linked Data. In this article, we have developed a framework for generating, enriching, and exploiting geospatial Linked Data from multiple and heterogeneous geospatial data sources. This proposal allows connecting two interoperability universes (SDIs, more specifically Web Feature Services, WFS, and Semantic Web technologies), which is evaluated through a study case in the (geo)biodiversity domain.

Geographic information retrieval method for geography mark-up language data / Caili Fang in ISPRS International journal of geo-information, vol 7 n° 3 (March 2018)  

Public [article]  inISPRS International journal of geo-information > vol 7 n° 3 (March 2018) Titre : Geographic information retrieval method for geography mark-up language data Type de document : Article/Communication Auteurs : Caili Fang, Auteur ; Shuliang Zhang, Auteur Année de publication : 2018 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] code source libre [Termes IGN] GML [Termes IGN] recherche d'information géographique Résumé : (Auteur) Geography Mark-up Language (GML) is the geographic information coding specification based on the Extensible Markup Language (XML) technology, which was developed by the Open GIS Consortium (OGC). GML expresses spatial and non-spatial attributes of geographic objects. Retrievals for traditional XML and geographic information have some limitations with respect to GML data, such as mismatching of the retrieval model, a single search form, and low retrieval quality. Based on analysis of the attributes, spatial relations, and structural features of GML data, this paper takes GML data elements as retrieval units and summarizes the GML retrieval mode. Then, the GML retrieval mode is constructed and formalized. On this basis, the GML Geographic Information Retrieval (GML_GIR) model is presented. The method implements the construction of a comprehensive index and the relative ordering of retrieval results by means of Lucene, an open-source full-text retrieval framework, and its components. For different features of GML data, corresponding relevance calculations are proposed. This study designs several different retrieval forms for GML data and simplifies the process of user information acquisitions. It provides reference methods for exploring geographical information retrieval based on semi-structured data represented by GML. Experimental results showed the efficiency and accuracy of the retrieval method.

Modelling, encoding and transforming of open geographic data to examine interoperability between GIS applications / Arif Cagdas Aydinoglu in Geocarto international, vol 31 n° 3 - 4 (March - April 2016)  

Public [article]  inGeocarto international > vol 31 n° 3 - 4 (March - April 2016) . - pp 446 - 461 Titre : Modelling, encoding and transforming of open geographic data to examine interoperability between GIS applications Type de document : Article/Communication Auteurs : Arif Cagdas Aydinoglu, Auteur Année de publication : 2016 Article en page(s) : pp 446 - 461 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] architecture orientée modèle [Termes IGN] données localisées numériques [Termes IGN] données ouvertes [Termes IGN] GML [Termes IGN] interopérabilité [Termes IGN] modélisation de processus [Termes IGN] norme de données localisées [Termes IGN] outil d'alimentation [Termes IGN] UML Résumé : (Auteur) The interoperability of geographic data sets is required between geo-information system applications to use geographic data sets effectively. Thus, international standardisation organisation/technical committee 211 standards supporting model-driven architecture were examined to test the ability of producing interoperable geographic data sets. With Turkey case, unified modelling language application schemas were designed for base geographic data themes and encoded to data interchange model based on geography markup language. To test the applicability of the open data models, extract-transform-load (ETL) tools were developed and applied for case applications such as topographic map and web urban atlas. This study gives a methodology and indicates that ETL tools should be created to enable multiple uses of geo-data sets without spending time and labour. However, data model design should be refined and kept as simple as possible because data transformation is laborious to use the models in the applications.

A WFS profile for the national urban planning website: géoportail de l’urbanisme [diaporama] / Marie Lambois (2016) 

Public Titre : A WFS profile for the national urban planning website: géoportail de l’urbanisme [diaporama] Type de document : Article/Communication Auteurs : Marie Lambois, Auteur Editeur : Paris [France] : Centre national de l'information géographique CNIG Année de publication : 2016 Conférence : EU conference INSPIRE 2016 26/09/2016 30/09/2016 Barcelone Espagne OA Proceedings Importance : 16 p. Format : pdf Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] Conseil national de l'information géographique [Termes IGN] format Shapefile [Termes IGN] France (administrative) [Termes IGN] géoportail [Termes IGN] GML [Termes IGN] norme de données localisées [Termes IGN] Web Feature Service Résumé : (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.
