<p><strong>Abstract.</strong> The study of spatial cognition has been one of important research domain for geographic information science. Recently our circumstance to acquire geographic information have been changed (e. g. Wakabayashi, Itoh, &amp; Nagami, 2011), so It is important to clarify the influence of the environmental change in the acquisition of spatial knowledge.</p><p>In this study we revealed relationships between the tendency to use geospatial information on smartphones and the acquisition of spatial knowledge. Currently, most people own smartphones and obtain transit information from them, such as train transit planners and Google maps, when they visit a place for the first time. The usage of geospatial information on smartphones significantly affects the accuracy of cognitive maps. Maps, including train route maps, present locational information widely, in a two-dimensional space; thus, users can understand the relationships among locations over a wide area. In contrast, the small displays of smartphones permit the concurrent viewing of only small areas of geospatial information. Locational information, such as the results of transportation planner applications, are typically described in a one-dimensional space, from start point to goal point.</p><p>Little is known regarding the effect of accessing geospatial information through smartphones on cognitive maps. The purpose of this study was to determine how people obtain locational information and how the experience of accessing locational information through smartphones affects the acquisition spatial knowledge regarding locations of places. To understand this spatial knowledge acquisition, we conducted two experiments.</p>

Geospatial Mapping

The chapter aims at drawing attention to the possibilities that geospatial technologies can bring to science mapping. In what follows, the chapter briefly distinguishes the notion of mapping between the Geospatial Information Science (GIScience) and Librarianship and Information Science (LIS). Afterwards, an overview about recent initiatives and research work relative to (geospatial) mapping of science is presented. Based on these examples, opportunities and challenges of applying geospatial technology to science mapping are discussed. Finally, based on relevant while evolving geospatial technologies, next steps for increasing up the influence of geospatial technology in science mapping are pointed out.

Common Understanding

The main objective of integrating Web GIS in airport emergency response should be to provide the most appropriate geospatial information to all participants. Airport emergency response still needs a model that will explain its complexity: its participants, their tasks and information needs. This paper presents the UML model of airport emergency response. Such a model facilitates a common understanding of the system by participants coming from airport, police, fire brigade, etc. It also enables institutional agreements for sharing data. The developers have got specifications of geospatial data and GIS functions imposed by participants and standards. A prototype Web GIS application is developed and presented to the users for evaluation. The prototype has shown how GIS functions can improve airport emergency response. The users have shown great interest, and they have great expectations in further integration of Web GIS in airport emergency response.

Sharing and reusing data in research is a welcome and encouraged practice since it maximises the scientific outcomes given limited financial, material and human resources. Interdisciplinary research is considered to benefit from this practice, uniting researchers and data from two or more disciplines to advance fundamental understanding or tackle problems whose solution is beyond the limit of an individual body of knowledge. Here we discuss the challenges of combining data across disciplines, focusing in particular on associating geographic location data with genetic data in the context of a project involving Crop Science and Geospatial Information Science disciplines. This project aims to improve understanding of how geographical, environmental and anthropogenic factors affect the genetic variation in a neglected and underutilised crop called Bambara groundnut.

Thematic Data

Traditional geospatial information platforms are built, managed and maintained by the geoinformation agencies. They integrate various geospatial data (such as DLG, DOM, DEM, gazetteers, and thematic data) to provide data analysis services for supporting government decision making. In the era of big data, it is challenging to address the data- and computing- intensive issues by traditional platforms. In this research, we propose to build a spatiotemporal cloud platform, which uses HDFS for managing image data, and MapReduce-based computing service and workflow for high performance geospatial analysis, as well as optimizing auto-scaling algorithms for Web client users’ quick access and visualization. Finally, we demonstrate the feasibility by several GIS application cases.

Situational Assessment

Enhancing situational awareness in real-time (RT) civil protection and emergency response scenarios requires the development of comprehensive monitoring concepts combining classical remote sensing disciplines with geospatial information science. In the VABENE++ project of the German Aerospace Center (DLR) monitoring tools are being developed by which innovative data acquisition approaches are combined with information extraction as well as the generation and dissemination of information products to a specific user. DLR’s 3K and 4k camera system which allow for a RT acquisition and pre-processing of high resolution aerial imagery are applied in two application examples conducted with end users: a civil protection exercise with humanitarian relief organisations and a large open-air music festival in cooperation with a festival organising company. This study discusses how airborne remote sensing can significantly contribute to both, situational assessment and awareness, focussing on the downstream processes required for extracting information from imagery and for visualising and disseminating imagery in combination with other geospatial information. Valuable user feedback and impetus for further developments has been obtained from both applications, referring to innovations in thematic image analysis (supporting festival site management) and product dissemination (editable web services). Thus, this study emphasises the important role of user involvement in application-related research, i.e. by aligning it closer to user’s requirements.
