There are significant issues and problems in the integration of remotely sensed data and GIS due to the differences in data characterisation, data structure and data processing philosophy between the two technologies. Difficulties exist particularly in handling large data volumes in GIS which are unavoidable when using remotely sensed imagery. This paper focuses on the integration of image data...

During the last few years, On-Line Analytical Processing (OLAP) has emerged as a valuable tool for the analysis, navigation and reporting of hierarchically organized data from data warehouses. It particularly gained popularity as a building block of modern decision-support systems. With the use of geographical information systems in conjunction with OLAP, the need for storing spatial data and p...

We test a conditional version of the International Capital Asset Pricing Model (ICAPM) accounting for the deviations from Purchasing Power Par...

Many geographical applications deal with spatial objects that cannot be adequately described by determinate, crisp concepts because of their intrinsically indeterminate and vague nature. Current geographical information systems and spatial database systems are unable to cope with this kind of data. To support such data and applications, we introduce vague spatial data types for vague points, va...

With the rapid development of wireless communication and sensor technologies, ubiquitous learning has become a promising solution to educational problems. In context-aware ubiquitous learning environments, it is required that learning content is retrieved according to environmental contexts, such as learners’ location. Also, a learning content retrieval scheme should be able to work with variou...

We investigate the antecedents of conflict on collocated as compared with geographically distributed teams. In our field study of 16 collocated and 20 geographically distributed research and development teams, we found little evidence that distributed teams have more conflict. However, we did find that distributed teams experienced more coordination problems and less healthy conflict handling n...
