We analyse the creation and production of British charts of the Adriatic from the first charting campaign of the Hydrographic Office of 1800–1801 to charts produced in the period of British rule over the island of Lissa of 1811–1815 to the first systematic hydrographic surveying of the Adriatic of 1817–1819 under the leadership of William Henry Smyth that resulted in the first hydrographic atlas and pilot book of the Adriatic. At the same time, the paper evaluates the British contribution to the creation of some of the first reliable nautical charts of the Adriatic and to the development of the nautical cartography of the Adriatic in general.

How large was the Earth in the sixteenth century? The length of the degree of latitude in the Iberian cartography of the Renaissance / Joaquim Alves Gaspar in Cartographic journal (the), Vol 52 n° 4 (November 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 4 (November 2015) . - pp 318 - 324 Titre : How large was the Earth in the sixteenth century? The length of the degree of latitude in the Iberian cartography of the Renaissance Type de document : Article/Communication Auteurs : Joaquim Alves Gaspar, Auteur Année de publication : 2015 Article en page(s) : pp 318 - 324 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie ancienne [Termes IGN] carte marine [Termes IGN] cartométrie [Termes IGN] Espagne [Termes IGN] géodésie ancienne [Termes IGN] Portugal [Termes IGN] seizième siècle Résumé : (Auteur) In this paper, the results of a cartometric analysis of a number of Portuguese and Spanish charts of the sixteenth and seventeenth centuries are presented and conclusions are drawn concerning the length of the degree of latitude adopted in the Iberian nautical cartography of the Renaissance. Under the light of what we know about the navigational and charting methods of the time, a new interpretation of the textual and cartographic sources is proposed. Rather than being the result of technical considerations or precise measurements, the adoption of the various standards during this long period appears to be no more than the echoes of the traditional models of the Earth and of the political disputes between Portugal and Spain.

Towards a deeper understanding of cartographic text visualisation : assessment of user preferences and colour influence / Rasha Deeb in Cartographic journal (the), Vol 52 n° 4 (November 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 4 (November 2015) . - pp 325 - 335 Titre : Towards a deeper understanding of cartographic text visualisation : assessment of user preferences and colour influence Type de document : Article/Communication Auteurs : Rasha Deeb, Auteur ; Kristien Ooms, Auteur ; Veerle Van Eetvelde, Auteur ; Philippe De Maeyer, Auteur Année de publication : 2015 Article en page(s) : pp 325 - 335 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] cartographie numérique [Termes IGN] couleur (rédaction cartographique) [Termes IGN] écriture cartographique [Termes IGN] fond cartographique [Termes IGN] lecture de carte [Termes IGN] typographie [Vedettes matières IGN] Cartologie Résumé : (Auteur) The main goal of this research is to investigate the influence of a map’s background colour on user preferences regarding labels’ typography, including their size, shape, orientation and texture. Four sets of backgrounds were tested: blank maps, grey scale, hot colours and cold colours. The foreground of these maps is populated with name labels, which are associated with point objects or areal objects. Bertin’s visual variables were applied to this set of name labels, both separately and in combination. User preferences of different typographic variations were registered and compared on the basis of different background colours using a one-way ANOVA. The results indicated that the typographic design of the map labels should not be adapted according to the map’s background colour.

Accurate attribute mapping from volunteered geographic information: issues of volunteer quantity and quality / Giles M. Foody in Cartographic journal (the), Vol 52 n° 4 (November 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 4 (November 2015) . - pp 336 - 344 Titre : Accurate attribute mapping from volunteered geographic information: issues of volunteer quantity and quality Type de document : Article/Communication Auteurs : Giles M. Foody, Auteur ; Linda M. See, Auteur ; Steffen Fritz, Auteur ; et al., Auteur Année de publication : 2015 Article en page(s) : pp 336 - 344 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Bases de données localisées [Termes IGN] acquisition de données [Termes IGN] analyse des besoins [Termes IGN] caractérisation [Termes IGN] données localisées des bénévoles [Termes IGN] localisant [Termes IGN] producteur [Termes IGN] qualité des données Résumé : (Auteur) Crowdsourcing is a popular means of acquiring data, but the use of such data is limited by concerns with its quality. This is evident within cartography and geographical sciences more generally, with the quality of volunteered geographic information (VGI) recognized as a major challenge to address if the full potential of citizen sensing in mapping applications is to be realized. Here, a means to characterize the quality of volunteers, based only on the data they contribute, was used to explore issues connected with the quantity and quality of volunteers for attribute mapping. The focus was on data in the form of annotations or class labels provided by volunteers who visually interpreted an attribute, land cover, from a series of satellite sensor images. A latent class model was found to be able to provide accurate characterisations of the quality of volunteers in terms of the accuracy of their labelling, irrespective of the number of cases that they labelled. The accuracy with which a volunteer could be characterized tended to increase with the number of volunteers contributing but was typically good at all but small numbers of volunteers. Moreover, the ability to characterize volunteers in terms of the quality of their labelling could be used constructively. For example, volunteers could be ranked in terms of quality which could then be used to select a sub-set as input to a subsequent mapping task. This was particularly important as an identified subset of volunteers could undertake a task more accurately than when part of a larger group of volunteers. The results highlight that both the quantity and quality of volunteers need consideration and that the use of VGI may be enhanced through information on the quality of the volunteers derived entirely from the data provided without any additional information.
