Legend design is one aspect of map design, which forms an important topic in cartography. From the literature, it is found that only one study was dedicated to the building of cartographic rules for effective legend design, and no systematic investigations into the building of grouping rules for proper determination of the grouping of legend features (symbols + text descriptions) had been carried out. This study is therefore devoted to the building of grouping rules based on Gestalt laws. An experimental evaluation of these developed rules was designed and conducted. The results indicate that a legend designed by considering these new rules is significantly more efficient than the others violating these rules.

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

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.

UN-GGIM: Europe Core Data to complement the INSPIRE framework [diaporama] / Dominique Laurent (2016) 

Public Titre : UN-GGIM: Europe Core Data to complement the INSPIRE framework [diaporama] Type de document : Article/Communication Auteurs : Dominique Laurent , 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 : 21 p.

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.

Problématiques de recherche autour de la notion de clutter en cartographie automatique / Guillaume Touya in Cartes & Géomatique, n° 226 (décembre 2015)

Il est indispensable de savoir mieux mesurer cette complexité afin de contrôler la qualité des cartes produites par des processus automatiques. Cet article rend compte de mesures existantes du clutter ou de la complexité, issues de différents domaines de recherche, et pointe le manque de méthodes adaptées à la conception automatique de cartes. Trois cas d'étude sont présentés pour illustrer le type de mesures requis pour améliorer l'automatisation de la généralisation cartographique, et de la spécification du style cartographique. Des verrous scientifiques sont déduits des problèmes pour traiter les cas d'étude avec les connaissances actuelles sur la complexité. Il en ressort notamment qu'une seule mesure ne peut pas saisir tous les aspects de la complexité des cartes et que la combinaison de mesures devrait être étudiée.

OpenStreetMap for cadastral purposes: an application using VGI for official processes in urban areas / S. Basiouka in Survey review, vol 47 n° 344 (September 2015)  

Public [article]  inSurvey review > vol 47 n° 344 (September 2015) . - pp 333 - 341 Titre : OpenStreetMap for cadastral purposes: an application using VGI for official processes in urban areas Type de document : Article/Communication Auteurs : S. Basiouka, Auteur ; Chryssy Potsiou, Auteur ; Efthimios Bakogiannis, Auteur Année de publication : 2015 Article en page(s) : pp 333 - 341 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cadastre étranger [Termes IGN] Athènes [Termes IGN] données localisées des bénévoles [Termes IGN] Grèce [Termes IGN] lever cadastral [Termes IGN] OpenStreetMap [Termes IGN] spécification de contenu [Termes IGN] web mapping Résumé : (auteur) The scope of the paper is to test if the online dynamic maps such as the OpenStreetMap (OSM) can be used for official mapping projects such as Cadastre, to investigate the advantages and the concerns of online and open to the public procedures and to identify those differentiations between experts and amateurs that play a critical role in such official projects. The specific research is focused on the use of OSM in urban areas as an alternative method to the official cadastral surveys. This paper presents the possibilities and the perspectives of OSM for spatial and attribute cadastral data collection and storage for the compilation of draft cadastral maps as an alternative methodology within the terms of the volunteered geographic information (VGI). The authors carried out a practical experiment in an extended part of the historic city centre of Athens and updated the online dynamic map of OSM with attribute and spatial cadastral data. Surveying students explored the capacities of the dynamic map in two steps: (a) in a section where the polygons of the buildings already existed on the map, they had to improve it with attribute data, and (b) in another section where no relevant polygons existed, a spatial and attribute data enhancement was required. The research was based on the various approaches that each student adopted and the freedom that the OSM offers to the users. The results show that users can easily distinguish the differences in capacities between the OSM and the commercial software; the inexpensive, easy to use and quick methodology of the OSM in contrast to the accurate, authoritative and assured methodology of the commercial software.
