This article explores how persuasive maps are manifesting themselves in the online world, comparing and contrasting online persuasive geocommunications with their paper map ancestors. The author ...discusses several social issues stemming from the widespread ability to use online mapping tools to make and distribute persuasive maps and argues that researchers have an excellent opportunity to observe the development of persuasive mapping techniques in real time as they continue to develop in conjunction with modern Web mapping technologies.
Information systems play a crucial role in supporting decision-making for managing and administrating territories at different levels of authority. Unfortunately, most such information systems are ...not dedicated to or customized for the special needs imposed by islands. In this work we describe the design, implementation, and operation of the 'Archipelago' digital repository, an integrated information system for supporting island research and development. The main objectives of the system are the storage, documentation, and dissemination of any kind of data regarding islands, as well as the provision of cartographic facilities for searching, visualization, and comparison. The basic principle of the system is the ability to geographically designate any stored material. The system is compatible with the standards for digital information documentation and interoperability, and it is based on free and open-source software tools.

The increase in the transaction of data and availability of augmented reality devices (virtual, augmented, and mixed reality) have led to the formation of a suitable environment for the realtime ...communication of complex air pollution data to a diverse population of individuals. In recent years, air pollution has become a global concern and thus it is important to constantly monitor air pollution and communicate it to citizens. In this study we design a web-based, 3-Dimensional virtual reality platform to portray air pollution risk through a realistic smog effect over the Joshua Tree Landscape. Through user natural language processing evaluation, this platform is shown to increase user risk perception of air pollution and its relation to environmental landscapes. Our model promotes the user's exploration of an air pollution landscape and provides tools to portray air pollution data to citizens.
The construction for thematic map symbol is a very complex and intelligent process. This symbol can be automatically generated and easily shared on the web through the syntactic characteristics of ...statistical indicators and cartography visualization. This paper expounds the symbol types, inner structure and its design pattern. And a syntactic construction theory based on phoneme (thematic map primitive) - word (single thematic symbol) - sentence (combined symbols or complex symbols) structure model is put forward for automatic construction of thematic map symbol. As a result of this research, symbols can be defined using cartographic primitives which are arranged according to its syntactic principles. Its concept and schema is discussed, and some examples are presented.
This paper describes a software configuration and data used for creating an interactive world atlas. Free software and data were chosen, and the potentials of such a choice are explored. The result ...is a simple interactive world atlas. Initial datasets, data presentation and user interface are established. The data are divided into three levels of detail that are usually found in printed atlases: the world, continents and countries. The possibility of data in one level of detail (the most detailed one) is explored, too. Special care was given to map projections in data presentation. The result is that every map is created in map projection according to knowledge on map projection selection for different geographical areas.
There is currently a high demand for spatial data usage within web applications. From a technical viewpoint, web services and geoportals aim to fulfil user requirements; however, the current ...cartographic methods do not satisfy the needs of the end users. The problem is more challenging when the final map contains data from various sources that have various cartographic characteristics; therefore, the vital information might be located under the base map layer. In this paper, we propose the concept of layer priorities as foreground, middle ground or background, and we propose the two following methods to enhance the symbolisation: polygon overlay and colour saturation methods. The results from two case studies show that these methods can satisfy the requirements of the end users.
Spatial statistic data is location related data which could be visualized on a map that forms a thematic map. Nowadays, more and more spatial related data could be reached through internet as the ...development of geospatial data sharing. Traditionally, cartography of these data is done by experts manually; however, automatic cartography of the spatial statistic data could be of value to the users in a distributed circumstance who have no knowledge of cartography. In this paper, domain ontology on web thematic mapping is defined, according to this ontology, a service-chain of web cartography services is generated which could handle the spatial statistic data and get a thematic map automatically.
The construction of thematic map symbols is a very complex and intellectually demanding process, but thematic symbols can be automatically generated and easily shared on the web using the syntactic ...structure of semantic symbols. In this paper, the symbol types, inner structure, and design pattern are discussed. A syntactic construction theory based on letter (thematic maps primitive)-word (single thematic symbol)-sentence (combined symbols or complex symbols) structure model is proposed to automate the construction of thematic map symbols. As a result of this research, symbols can be defined using cartographic primitives which are arranged according to syntactic principles. A semiotic model and word-centered construction theory can be integrated into interactive cartography as represented by the technology of Internet. Finally, the concepts and schema of this theory are discussed, and some examples are presented based a web thematic cartographic system to verify its utility.
Social Studies, including history and geography, is a core part of most state curriculum standards for K-12 education, and for the most part is in need of improvement. Among the technological ...solutions that have been developed, interactive maps show promise in making the complexities of the social sciences (especially historical geography) more interesting to students, and easier to visualize and understand, without demanding significant investments by schools. A two-group experiment examined this potential for the 7th Grade Utah Studies curriculum. After completing an exercise to analyze possible historical and geographical causes of settlement patterns in Utah, students using interactive maps showed significantly better improvement between a pretest and posttest than students using paper maps. Although some of the test results were inconclusive and highlighted technological and resource obstacles to the widespread adoption of interactive mapping in the classroom, it has been shown to help students learn social studies in a deeper, more engaging manner.
Atlas information systems (AIS) present spatial information on predefined themes and localities in the form of maps and other representations, generally focusing on correct cartographic appearance ...and offering a certain degree of user interaction. This article introduces the concept of modular AIS, a concept that is essential for the development of an AIS with modern computer technology. The main advantages of a modular architecture are twofold: first, an AIS software framework based on a modular architecture allows for easy and rapid customization to a certain theme and locality; second, functional enhancements and new technologies can be easily integrated into a modular AIS in order to optimally present and analyse the data at hand.
Web-based AIS can benefit from the concept of modularity at three different levels: (1) The AIS client can adjust its functionality and adapt to the available technology on the present computer platform. (2) The AIS server can build an AIS client with custom-tailored data and functionality in real time, depending on the user's access rights, needs, or expertise. (3) Distributed, modular data storage greatly simplifies the design, implementation and maintainance of an AIS by using a mediation system.
To illustrate the concepts presented, we will discuss selected technical aspects (e.g., Web-based map viewer technology, client–server communication), and describe an exemplary Web-based AIS that extends the modular core architecture through specialized functionalities for the analysis of geophysical data. It is the authors’ hope that the ideas presented will provide an introduction to the technical concepts for designers and developers of similar Web-based atlas information systems.
