This article introduces and analyses four classic functionality research techniques (monitoring, examination, feedback registration, and experiment) drawn from the scientific literature and suggests two new research techniques (qualimetry and conversion) based on the author's research. The author suggests distinguishing four main indicators that in general would describe the weak and strong features of research techniques: length of research, costs of research organization, objective of research, and applicability of results. The principal aim of the analysis is to help define the most important advantages and disadvantages of functionality research techniques. The article first describes types of interactive maps and their function groups, then proceeds to the analysis of the six suggested functionality research techniques. http://utpjournals.metapress.com/content/j3463366h74450kp/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/j3463366h74450kp/?p=a347796716c348 3899817718fd129446&pi=1> &pi=1 DOI: 10.3138/carto.46.2.66 A User Study of a Map-Based Slideshow Editor Hideyuki Fujita, Masatoshi Arikawa Our research goal is to facilitate the sharing of stories with digital maps. Today, many kinds of my map applications allow users to create maps that display personal collections of places visited, along with photographs, videos, and texts. The authors of such maps can organize and publish their collections of places by creating maps, and viewers can browse these collections freely by panning and zooming the maps or searching by location. It is difficult, however, for authors to represent their experiences as a sequence of events, mainly because it is up to the viewer to decide which map locations will be viewed, and in what order. Therefore, one future requirement for this type of map application is to facilitate map-based storytelling. The objective of this study is to identify and discuss the characteristics of map-based stories and the effectiveness of maps in editing them. To help users communicate map-based stories in a more narrative fashion, we have developed software for mapping photo collections and creating slideshows to present travelogues, sightseeing guides, and so on, which we call a map-based slideshow. In this article, we analyse user-created, map-based slideshows, focusing on the spatiotemporal relationships among the photographs that compose the slideshow. We also describe a user study focusing on how and in which order users edit map-based slideshows. The results show characteristics of the spatiotemporal structures of map-based stories. We also evaluated the effectiveness of maps in the user's story-editing process. Because the spatial slideshow is a typical form of map-based story, we assume that most of the knowledge acquired is applicable not only to map-based slideshows but also to other map-based stories, such as a tour of Google Earth. http://utpjournals.metapress.com/content/j551w63382j82248/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/j551w63382j82248/?p=a347796716c348 3899817718fd129446&pi=2> &pi=2 DOI: 10.3138/carto.46.2.74 Improving Web Mapping with Generalization Julien Gaffuri Maps are not like other images. Internet maps could be improved through the use of automated mapping methods, particularly automated generalization techniques. Operational automated generalization systems exist, but they are not used on the Web. Integrating generalization and Web-mapping systems is an important challenge for Internet cartography; this integration requires that the architecture of existing Web-mapping systems be improved. This article gives some recommendations to progress toward this integration: spatial data servers should diffuse more vector data and fewer pre-computed raster tiles; they should be made scale aware and should provide multi-scale data; the generalization transformations should be shared between servers and clients; and Web-mapping clients should be able to compute dynamic graphic generalizations to adapt the spatial data display to the user's needs. http://utpjournals.metapress.com/content/3312042w30l19g53/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/3312042w30l19g53/?p=a347796716c348 3899817718fd129446&pi=3> &pi=3 DOI: 10.3138/carto.46.2.83 Cartographic Quality Issues for View Services in Geoportals Lars Harrie, Sébastien Mustière, Hanna Stigmar Following the INSPIRE directive, several countries are now setting up geoportals. These geoportals have view services that offer new opportunities for users to easily display rich and personalized geographic data. However, they also raise new challenges. One challenge is the absence of the traditional cartographer, which sets requirements for the development of automatic methods that optimize the presentation of the data. This article discusses five issues for the improvement of map presentationsemantics, geometries, levels of detail, labels, and symbolsand reviews some related methods. The development of this type of method is essential for the success of view services in the future. http://utpjournals.metapress.com/content/u5p4552738021513/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/u5p4552738021513/?p=a347796716c348 3899817718fd129446&pi=4> &pi=4 DOI: 10.3138/carto.46.2.92 Improving Accessibility Information in Pedestrian Maps and Databases Mari Laakso, Tapani Sarjakoski, L. Tiina Sarjakoski As populations age, more and more people have some kind of restrictions on their mobility. In order to increase the potential of mobility-impaired persons to move around and navigate independently, information on the accessibility of the environment should be supported by map services and delivered together with spatial information to their devices for personal navigation. Spatial databases for pedestrian route planning should contain more detailed information on accessibility, such as pavement surfaces, slopes, and stairs. This study examines a wide range of examples of map services in Finland in terms of the extent to which they support accessibility. The authors then provide and discuss a proposal for the information content of a geospatial database to fulfil the requirements of users with impairments. With guidelines for data content, data classification, and functionality, map information can be developed so that it is also more useful for special user groups and makes the environment more accessible for everyone. http://utpjournals.metapress.com/content/427353556v622g74/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/427353556v622g74/?p=a347796716c348 3899817718fd129446&pi=5> &pi=5 DOI: 10.3138/carto.46.2.101 Online Visualization of 3D City Model Using CityGML and X3DOM Bo Mao, Yifang Ban This article proposes a novel framework for online visualization of 3D city models. CityGML is used to represent the city models, based on which 3D scenes in X3D are generated, then dynamically updated to the user side with AJAX and visualized in WebGL-supported browsers with X3DOM. The experimental results show that the proposed framework can easily be implemented using widely supported major browsers and can efficiently support online visualization of 3D city models in small areas. For the visualization of large volumes of data, generalization methods and multiple-representation data structure should be studied in future research. http://utpjournals.metapress.com/content/l006k15103150604/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/l006k15103150604/?p=a347796716c348 3899817718fd129446&pi=6> &pi=6 DOI: 10.3138/carto.46.2.109 Quality Analysis of OpenStreetMap Data Based on Application Needs Juliane Mondzech, Monika Sester More volunteered geographic information is becoming available; if this information is to be exploited, its quality must be known. This study evaluates the quality of OpenStreetMap data with respect to its fitness for use (i.e., its suitability for a certain application), specifically pedestrian navigation. The quality of the data is determined by comparing simulated routes on two networks; one data set is from OSM, and the other is the German topographic data set, ATKIS. Both accessibility and length of routes are used as quality criteria. The two data sets are tested using three different test scenarios in Germany. http://utpjournals.metapress.com/content/d815571134382u31/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/d815571134382u31/?p=a347796716c348 3899817718fd129446&pi=7> &pi=7 DOI: 10.3138/carto.46.2.115 Technical Notes & Ephemera http://utpjournals.metapress.com/content/m347440mm177t465/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/m347440mm177t465/?p=a347796716c348 3899817718fd129446&pi=8> &pi=8 DOI: 10.3138/carto.46.2.126 Tug of War at the Border Joseph M. McCollum Rugby, North Dakota claims the distinction of being the geographic centre of North America. The author examines this claim and attempts to compute the true location of the geographic centre of North America. The author concludes that an iterative method based on the Lambert Azimuthal Equal Area (LAEA) projection, which slightly understates distance, and the Azimuthal Equidistant projection, which slightly overstates area, is the best method for computing the geographic centre of a given area. Six different definitions of North America are considered, and a proposed centre is offered for each definition. http://utpjournals.metapress.com/content/6x12322n4r75wh62/?p=a347796716c3483 899817718fd129446 <http://utpjournals.metapress.com/content/6x12322n4r75wh62/?p=a347796716c348 3899817718fd129446&pi=9> &pi=9 DOI: 10.3138/carto.46.2.127 Seventh ICA Mountain Cartography Workshop: Mountain Mapping and Geospatial Information Retrieval (Borsa, Maramures, Romania, 15 September 2010) Gabriela Ilies, Tom Patterson, Lorenz Hurni, et al. http://utpjournals.metapress.com/content/n5721280241x3u75/?p=e9ed683e4a2d4eb b9f20c9e1399b5171 <http://utpjournals.metapress.com/content/n5721280241x3u75/?p=e9ed683e4a2d4e bb9f20c9e1399b5171&pi=10> &pi=10 DOI: 10.3138/carto.46.2.134 Annual Meeting of the Canadian Cartographic Association (University of Regina, Saskatchewan, 15 June 2010) Roger Wheate http://utpjournals.metapress.com/content/7627840788x58543/?p=e9ed683e4a2d4eb b9f20c9e1399b5171 <http://utpjournals.metapress.com/content/7627840788x58543/?p=e9ed683e4a2d4e bb9f20c9e1399b5171&pi=11> &pi=11 DOI: 10.3138/carto.46.2.137 Reviews of Books & Atlases http://utpjournals.metapress.com/content/pq34414060j32457/?p=e9ed683e4a2d4eb b9f20c9e1399b5171 <http://utpjournals.metapress.com/content/pq34414060j32457/?p=e9ed683e4a2d4e bb9f20c9e1399b5171&pi=12> &pi=12 DOI: 10.3138/carto.46.2.139 _____ Cartographica Cartographica, the international journal for geographic information and geovisualization, is now available electronically and includes the complete back file of previously published articles going back to 1964 with issue 1.1, when Cartographica was known as The Cartographer.
