Projection Wizard – An online map projection selection tool / Bojan Šavrič in Cartographic journal (the), Vol 53 n° 2 (May 2016)  

Public [article]  inCartographic journal (the) > Vol 53 n° 2 (May 2016) . - pp 177 - 185 Titre : Projection Wizard – An online map projection selection tool Type de document : Article/Communication Auteurs : Bojan Šavrič, Auteur ; Bernhard Jenny, Auteur ; Helen Jenny, Auteur Année de publication : 2016 Article en page(s) : pp 177 - 185 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Projections [Termes IGN] application web [Termes IGN] outil d'aide à la décision [Termes IGN] projection [Termes IGN] rédaction cartographique [Termes IGN] service web [Termes IGN] web mapping Résumé : (Auteur) The selection of map projections is difficult and confusing for many. This article introduces Projection Wizard, an online map projection selection tool available at projectionwizard.org that helps mapmakers select projections. The user selects the desired distortion property, and the area to be mapped on an interactive web map. Projection Wizard then proposes a projection, along with projection parameters (such as standard parallels). The tool also creates a preview map with the proposed projection, and provides the corresponding projection code in PROJ.4 format, if applicable. The automated selection process is based on John P. Snyder's selection guideline with a few adjustments. This article discusses the automated selection process, and the map projections suggested. Projection Wizard solves the problem of map projection selection for many applications and helps cartographers and GIS users choose appropriate map projections.

Challenges in adapting example-based texture synthesis for panoramic map creation: a case study / Helen Jenny in Cartography and Geographic Information Science, vol 40 n° 4 (September 2013)  

Public [article]  inCartography and Geographic Information Science > vol 40 n° 4 (September 2013) . - pp 297 - 304 Titre : Challenges in adapting example-based texture synthesis for panoramic map creation: a case study Type de document : Article/Communication Auteurs : Helen Jenny, Auteur ; Bernhard Jenny, Auteur Année de publication : 2013 Article en page(s) : pp 297 - 304 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie [Termes IGN] déformation géométrique [Termes IGN] image panoramique [Termes IGN] peinture [Termes IGN] synthèse d'image [Termes IGN] texture d'image Résumé : (Auteur) Panoramic hiking and skiing maps are popular among tourists and map collectors. Such three-dimensional (3D) maps allow for easy orientation and provide the observer with an immersive impression of the landscape to be discovered or remembered. The most impressive panoramic masterpieces are almost exclusively painted manually or with minor digital tool support. Software packages that allow modern cartographers to create 3D maps of comparable visual quality (semi-) automatically are currently not available. Computer graphics has developed a number of methods for painterly rendering, including imitating the characteristics of a panorama artist's brush stroke and raster-based methods that synthesize new texture from examples. In this article, the latter approach is explored, and the idea of creating terrain textures for arbitrary regions by reassembling them from pieces of scanned hand-painted masterworks is pursued. Panorama painters vary the appearance of land cover depending on terrain characteristics and viewing parameters. This article suggests how the example-based texture synthesis approach could be adapted to accommodate such dependencies. A case study of transferring the appearance of H.C. Berann's hand-painted panorama of the Swiss Jungfrau region to a digital panorama of a different region is presented. The case study shows that a number of previously unanticipated hurdles are encountered when using hand-painted panoramas as input to an example-based texture synthesis algorithm. By identifying the challenges of applying texture-by-example to panoramic map making and by suggesting possible solutions, the authors aim to promote the creation of more visually appealing and legible digital panoramic maps.

Interactive design of 3D maps with progressive projection / Helen Jenny in Cartographic journal (the), vol 47 n° 3 (August 2010)  

Public [article]  inCartographic journal (the) > vol 47 n° 3 (August 2010) . - pp 211 - 221 Titre : Interactive design of 3D maps with progressive projection Type de document : Article/Communication Auteurs : Helen Jenny, Auteur ; Bernhard Jenny, Auteur ; Lorenz Hurni, Auteur Année de publication : 2010 Article en page(s) : pp 211 - 221 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image [Termes IGN] cartographie 3D [Termes IGN] courbure de la Terre [Termes IGN] modélisation 3D [Termes IGN] paysage [Termes IGN] projection perspective [Termes IGN] visualisation 3D Résumé : (Auteur) The progressive projection is by origin a manual cartographic technique, traditionally used by panoramic landscape painters; however, it is rarely encountered in digitally created three-dimensional (3D) maps. In this article, the advantages of this specific projection when designing 3D maps are presented, the processes involved in its manual construction, as well as the existing and potential digital implementation approaches, are reviewed. A new algorithmic solution is described, allowing for user-friendly interactive bending of a terrain model into a progressive view, with options to add a curved horizon, to vertically exaggerate the terrain, and to create a 360° strip panorama. The resulting software, Terrain Bender, is freely available for download.
