With the popularity of mobile devices, numerous mobile applications have been and will continue to be developed for various interesting usage scenarios. Riding this trend, recent research community envisions a novel information retrieving and information-sharing platform, which views the users with mobile devices, being willing to accept crowdsourcing tasks ascrowd sensors. With the neat idea, a set of crowd sensors applications have emerged. Among the applications, the geospatial information systems based on crowd sensors show significant potentials beyond traditional ones by providing real-time geospatial information. In the applications, user positioning is of great importance. However, existing positioning techniques have their own disadvantages. In this paper, we study using pervasive Wi-Fi access point as user position indicators. The major challenge for using Wi-Fi access point is that there is no mechanism for mapping observed Wi-Fi signals to human-defined places. To this end, our idea is to employ crowdsourcing model to perform place name annotations by mobile participants to bridge the gap between signals and human-defined places. In this paper, we propose schemes for effectively enabling crowdsourcing-based place name annotation, and conduct real trials with recruited participants to study the effectiveness of the proposed schemes. The experiment results demonstrate the effectiveness of the proposed schemes over existing solutions.

In this chapter, the authors discuss the state-of-the-art of Geo-Social systems and Recommender systems, which are becoming extremely popular for users accessing social media trough mobile devices. Moreover, they introduce a general framework based on the interaction among those systems and the “Game With A Purpose” (GWAP) paradigm. The proposed framework/platform can help researchers to understand geo-social dynamics in order to design and test new services, such as recommenders of places of interest for tourists, real-time traffic information systems, personalized suggestions of social events, and so forth. To target the governance of such complexity, relevant data must be collected by the investigators, shared with the community, and analyzed to find dynamical patterns that correlate spatial-temporal information with the user’s preferences and objectives. The authors argue that the GWAP approach can be exploited to successfully satisfy many of these tasks.

Everyone involved in geospatial information systems has heard of Environmental Systems Research Institute (Esri)company. Most people have tried ArcGIS software at least for one time. Esri has been the pioneer in this industry for a long time; it also defines the future of geospatial trends. In this chapter, the author adopts a neutral position to discuss the relation of Esri and open-source community. They cover almost every aspect where Esri and open source co-occur. Even the latest achievement of Esri, which is R-bridge, is discussed here. Going into the details of everything is not the goal of the chapter; however, a minimum description is provided for each section. Proper references are given to the reader for further study.

Most existing augmented reality (AR) applications are suitable for cases in which only a small number of real world entities are involved, such as superimposing a character on a single surface. In this case, we only need to calculate pose of the camera relative to that surface. However, when an AR health or environmental application involves a one-to-one relationship between an entity in the real-world and the corresponding object in the computer model (geo-referenced object), we need to estimate the pose of the camera in reference to a common coordinate system for better geo-referenced object registration in the real-world. New innovations in developing cheap sensors, computer vision techniques, machine learning, and computing power have helped to develop applications with more precise matching between a real world and a virtual content. AR Tracking techniques can be divided into two subcategories: marker-based and marker-less approaches. This paper provides a comprehensive overview of marker-less registration and tracking techniques and reviews their most important categories in the context of ubiquitous Geospatial Information Systems (GIS) and AR focusing to health and environmental applications. Basic ideas, advantages, and disadvantages, as well as challenges, are discussed for each subcategory of tracking and registration techniques. We need precise enough virtual models of the environment for both calibrations of tracking and visualization. Ubiquitous GISs can play an important role in developing AR in terms of providing seamless and precise spatial data for outdoor (e.g., environmental applications) and indoor (e.g., health applications) environments.

Pipeline projects see enormous benefit from using geospatial information systems since a pipeline will commonly cover large geographic distances. In doing so, terabytes of engineering, geotechnical, and environmental data can be generated for engineering and regulatory needs. A central database allows the project to organize this information and provide a single source of truth. In fact, the central database is as much a philosophy as it is computer infrastructure. This level of organization allows a project to properly manage change, thus ensuring data integrity and security. When data is reliable and secure, its full value can be realized during the pipeline planning stage and even further leveraged through construction and operation.

Augmented reality (AR) is the integration of digital information with the user’s environment in real time. AR software use in many different ways and for the needs of cartography too. This technology may be useful for the development of navigational mobile applications and actions with static (paper) maps. There are two main operating modalities for implementation of augmented reality in applications: by markers and by the positioning of customer and surrounding objects (by azimuths determination between customer’s device and real objects). The first way is applied for static maps when another way is applied for navigational mobile applications. Augmented reality provides at least six opportunities, which create better options for working with design and content of maps for cartographers. This technology also provides the new experience in the work on maps for customers. The advantages of using augmented reality in cartography are the partial equation of static maps to geographical information systems, adaptability of cartographic images to the needs of users, improving the quality of design and content possibilities of maps and making actions with maps more attractive for customers. However, this technology is not without disadvantages, which connected with the development of AR-applications and requirements to smartphones. In addition, this article reveals aspects of the creation of augmented maps in cartographic companies.
