A comparison of usefulness of 2D and 3D representations of urban planning / Grant Herbert in Cartography and Geographic Information Science, Vol 42 n° 1 (January 2015)

Urban planning has moved toward a 3D, geographic-information-system-centric, and functional decision support framework. This study aims to examine the preferences of urban planning professionals with respect to 2D and 3D visualizations in a case study. The authors built a 3D representation of a proposed building along with the existing urban environment in Queenstown, New Zealand and conducted a usefulness test through a survey and interview. Based on the survey, the study evaluated the degree of task utility perceived in each visualization method, the effect on the mental image, and shadow representation preferences. The findings support the literature that the benefits of using a 2D or 3D model are closely related to the types of planning tasks undertaken. The findings also reveal a complex view of planning activities, suggesting that planners themselves cannot be treated as a single group for research purposes.

A comparative analysis of routes generated by Web Mapping APIs / Monsak Socharoentum in Cartography and Geographic Information Science, Vol 42 n° 1 (January 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 1 (January 2015) . - pp 33 - 43 Titre : A comparative analysis of routes generated by Web Mapping APIs Type de document : Article/Communication Auteurs : Monsak Socharoentum, Auteur ; Hassan A.

Among maps and map functionalities provided through WMAs, route and direction are prominent and commonly available. Given that each WMA uses a different map database and a different set of assumptions, the routes they generate, for the same pairs of origin and destination addresses, are different. Considering the current void in literature on WMAs and the routes they generate, in this paper, select common WMAs are compared and analyzed based on their routing techniques. The results of these comparisons will benefit researchers by helping them better understand the behavior of WMAs in producing routes, which in turn can be used for selecting suitable WMAs for research projects or developing applications (such as navigation and location-based services). The process in which routes are evaluated can also be used as a guideline to help researchers explore behavior of WMAs in generating routes.

A method based on graphic entity for visualizing complex map symbols on the web / Jinqu Zhang in Cartography and Geographic Information Science, Vol 42 n° 1 (January 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 1 (January 2015) . - pp 44 - 53 Titre : A method based on graphic entity for visualizing complex map symbols on the web Type de document : Article/Communication Auteurs : Jinqu Zhang, Auteur ; Yunqiang Zhu, Auteur Année de publication : 2015 Article en page(s) : pp 44 - 53 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] carte interactive [Termes IGN] cartographie par internet [Termes IGN] données vectorielles [Termes IGN] Flash (logiciel) [Termes IGN] format SVG [Termes IGN] Kouangtoung (Chine) [Termes IGN] objet géographique complexe [Termes IGN] sémiologie graphique [Termes IGN] symbole graphique [Termes IGN] web mapping Résumé : (auteur) A method based on graphic entity for map symbol visualization in vector-based web mapping is proposed. The method is especially effective for complex geological symbols. It has three parts: graphic entity library, symbol synthesizer, and synthesis specifications. The design process is described as the application of the method to symbols representing point, line, and polygon features in web mapping. The method works with Flash, SVG, or other mapping technologies. We chose Flash to visualize geological disaster information for the Guangdong province in China. The case study demonstrates that this graphic entity-based method can meet the demands for interactive symbolization and complex symbol visualization in Internet web mapping. It produces good results, is fast, and is easy to operate. This makes it especially suitable for web-mapping applications, especially vector-based and hybrid WebGIS applications which display complex symbols.

Automatic mapping and innovative on-demand mapping services at IGN France / Sylvain Lafay in Cartography and Geographic Information Science, Vol 42 n° 1 (January 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 1 (January 2015) . - pp 54 - 68 Titre : Automatic mapping and innovative on-demand mapping services at IGN France Type de document : Article/Communication Auteurs : Sylvain Lafay , Auteur ; Arnaud Braun , Auteur ; David Chandler , Auteur ; Michaël Michaud, Auteur ; Lucille Ricaud, Auteur ; Sébastien Mustière , Auteur Année de publication : 2015 Article en page(s) : pp 54 - 68 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] GeoServer [Termes IGN] légende cartographique [Termes IGN] modèle cartographique [Termes IGN] Styled Layer Descriptor [Termes IGN] Web Map Service Résumé : (auteur) Mapmaking has become widespread through the Internet, resulting in a wide range of cartographic quality. To achieve better quality, mapmaking needs tools and online services for intuitive and efficient on-demand mapping. A project team at IGN, the French National Mapping Agency, is working on producing a digital cartographic model (DCM) from various existing databases and maps on which such tools and services are based. This DCM ranges from detailed topographic maps to small general road maps. GeoServer Web Map Service capabilities were used extensively to produce quality maps with various legends. Special care was taken to make a default legend suitable for customer data overlays, both on-screen and on paper. Web-based interface prototypes were built to guide users in choosing colors and creating their own original map legends. Users can also rely on a growing catalog of harmonious color palettes and map samples as sources of inspiration.

Detection and correction of inconsistencies between river networks and contour data by spatial constraint knowledge / Tinghua Ai in Cartography and Geographic Information Science, Vol 42 n° 1 (January 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 1 (January 2015) . - pp 79 - 93 Titre : Detection and correction of inconsistencies between river networks and contour data by spatial constraint knowledge Type de document : Article/Communication Auteurs : Tinghua Ai, Auteur ; Min Yang, Auteur ; Xiang Zhang, Auteur ; Jing Tian, Auteur Année de publication : 2015 Article en page(s) : pp 79 - 93 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] cohérence des données [Termes IGN] programmation par contraintes [Termes IGN] réseau fluvial Résumé : (auteur) In the representation of topographic data, the distribution of hydrographic networks should be constrained by the contour model’s landform features. During the integration of topographic databases, however, spatial conflicts may destroy these constraints, generating inconsistencies. This study presents a method to detect and correct inconsistencies between river networks and contour data by spatial knowledge. First, structured terrain features are extracted from the contour-based geometric representation and matching relationships between rivers and contours are constructed based on spatial knowledge of the distribution of rivers and talwegs. We then propose a distance metric for measuring differences and identifying inconsistencies between the matched river and contour features. Three correction approaches are provided for different inconsistency situations, including river adjustment referenced to the contour, contour adjustment referenced to the river and adjustment of both river and contour to middle positions. We apply the proposed method to the integration and maintenance of national topographic infrastructure in order to demonstrate its effectiveness.
