Abstract. Research in geographic information science has not yet found clear answers to the questions of what geographic information is about or what a geographic information system (GIS) contains. This lack of consensus makes it especially challenging to teach and learn GIS. Existing pedagogical approaches either focus on the representational level of data (e.g., “raster and vector”) or are too generic (e.g., “geo-referenced information”). This characterization of GIS and its content is difficult for learners to transfer and apply broadly. As instructors, we approach the challenge of teaching GIS from a conceptual basis. We describe our process to develop a set of core concepts of spatial information, which we use to redesign an undergraduate-level introductory GIS course. Our intervention focuses instruction on the kinds of questions that geographic information enables before training students to produce workflows and answers through system commands. The course redesign complements and informs ongoing research on core concepts of spatial information. Our results demonstrate that GIS courses can deliver more than software training, indicating both theoretical gains and didactic challenges.

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. The acronym GIS is sometimes used for geographic information science (GIS science) to refer to the academic discipline that studies geographic information systems and is a large domain within the broader academic discipline of geoinformatics. GIS can provide the airport management staff with visual pavement information and powerful analysis tool. Meanwhile, the spatial information managed by GIS can ensure the accumulation of valid attribute data of airport. Based on the principle and general implementation process of GIS and the characteristics of airport pavement management, this paper describes the implementation process of GIS in Airport planning and design. To organize the spatial entities effectively, some layers are set according to the characteristics of spatial entities. The spatial database is established, and then the function design of the GIS software is presented including map exploring, map locating, spatial query, rendering style of map and output of map. Finally, in this paper, an overview of locating airports using GIS studied.

Geographic Information Science focuses traditionally on spatial information of geographic scale and associates this per default with outdoor environments. Systems, databases and models are designed for this primary purpose. In this paper, the author discusses the geographic information requirements in indoor environments and, in particular, their differences to ‘outdoor’ geographic information. The main difference, as argued, is that the third dimension is an essential factor for indoor spatial information, while this is not necessarily so for outdoor information. As a consequence, information technology designed for outdoors is not necessarily fit to model, analyze or communicate about indoor space.

Abstract. Over the past decade, the introduction of new technologies in different markets has led to the emergence of smart destinations by providing stakeholders with effective and efficient technological solutions. The objective of smart destinations is to improve spatial competitiveness.Tourism with its focus on travel and the transfer of people, goods, and services across time and space is essentially a geographic phenomenon. The central themes of the research field of traditional geography focus on three related topics: place, space, and environment.The trend toward big data has had a significant impact on all sectors from which geographic information science has had a major impact on how organizations acquire and leverage spatial information. Looking at how organizations are using geographic information science and technology, one of the clearest themes is that usage is expanding rapidly; while traditionally the largest adopters of geospatial data have been government agencies, it is now easy to see widespread adoption of GIS across all industries. On the one hand, to act on the country's income through a wider and more targeted geographic attractiveness and on the other hand, to improve the investment fields in the most visited areas and to create a favorable tourism environment in areas whose attractiveness remains low.

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. GIS (more commonly GIS science) sometimes refers to geographic information science (GIS science), the science underlying geographic concepts, applications, and systems. GIS can refer to a number of different technologies, processes, techniques and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization.

Information use is an understudied area within information science thus strategies pertinent to using information remains understudied. However, research implicates strategically using information as a performance booster, especially within academic contexts. This paper reports on an ongoing research on information use strategies of graduate students as they attend to an identified academic task.L’utilisation et les stratégies pertinentes à l’utilisation de l’information demeurent un domaine sous-étudié en science de l’information. Cependant, la recherche implique l’utilisation stratégique de l’information comme stimulant du rendement, particulièrement en contexte scolaire. Cette communication porte sur une recherche en cours sur les stratégies d’utilisation de l’information des étudiants universitaires de 2e et 3e cycle lors d’une tâche scolaire prédéfinie.

Liquid Suspensions

Crystallisation is a crucial step in many industrial processes. Many sensors are being investigated for monitoring such processes to enhance the efficiency of them. Ultrasound techniques have been used for particle sizing characterization of liquid suspensions, in crystallisation process. An ultrasound tomography system with an array of ultrasound sensors can provide spatial information inside the process when compared to single-measurement systems. In this study, the batch crystallisation experiments have been conducted in a lab-scale reactor in calcium carbonate crystallisation. Real-time ultrasound tomographic imaging is done via a contactless ultrasound tomography sensor array. The effect of the injection rate and the stirring speed was considered as two control parameters in these crystallisation functions. Transmission mode ultrasound tomography comprises 32 piezoelectric transducers with central frequency of 40 kHz has been used. The process-based experimental investigation shows the capability of the proposed ultrasound tomography system for crystallisation process monitoring. Information on process dynamics, as well as process malfunction, can be obtained via the ultrasound tomography system.
