This paper describes a Linked Data service that supports the navigation and retrieval of geographical entities for the UK territory. Geographical entities, in the extent of this paper, are linked data resources that describe objects that have a geographical extension. The service presented in this paper allows the querying of resources that contain or are contained by a given entity URI. The re...

The visual analysis of geographically referenced datasets with a large number of attributes is challenging due to the fact that the characteristics of the attributes are highly dependent upon the locations at which they are focussed and the scale at which they are measured. Here, we develop attribute signatures – interactively crafted graphics that show the geographic variability of statistics ...

Today, the thematic layer is still the prevailling structure in geomatics for handling geographical information. However, the layer model is rigid: it implies partitionning geographical data in predefined categories and using the same description schema for all elements of a layer. Recently, Logical Information Systems (LIS) introduced a new paradigm for information management and retrieval. Us...

Ocean modelling requires the production of high-fidelity computational meshes upon which to solve the equations of motion. The production of such meshes by hand is often infeasible, considering the complexity of the bathymetry and coastlines. The use of Geographical Information Systems (GIS) is therefore a key component to discretising the region of interest and producing a mesh appropriate to ...

Modern electronic positioning systems are capable of locating a point in the vicinity of the Earth’s surface to very high precision. Depending on the sophistication of equipment in use, whether the requirement is relative or absolute and the data processing time available, accuracy from 10 m down to a few millimetres can be achieved in three dimensions. While it is not difficult to measure the ...

The success of information systems relies on their capabilities to provide users with the relevant information they need, when they need it. Meeting these requirements will result in improving response times and decision-making processes. Geographic information system (GIS) is one instance of such systems where data are usually relative to a specific application. To extend this dataset, we prop...

Despite enormous efforts in quantification, our understanding of many of the Earth’s systems remains non-axiomatic; the systems are ‘open’ and consequently it is not possible to deduce all outcomes from known laws. Science must therefore adopt a manner that encourages the creation or uncovering of new knowledge (Baker, 1999; Takatsuka & Gahegan, 2001). For this reason aloneand completely uncou...

This paper focuses on private sources of knowledge specifically customers and competitors as sources of innovative activity. Our main argument is that the two sources are correlated even after controlling for several factors at the level of technology, individual and organization. What is more, we show that the geographical distance of these sources modifies the intensity of this correlation, i...

This empirical study focuses on the impact of an information technology (IT), specifically electronic mail (e-mail), on three basic organization components: structure, people, and tasks. An Organizational Interaction Diamond (OID) model is developed illustrating how each component enables changes in other components interacting with the organization’s internal and external environments. The org...

Globally distributed software development is facing challenges brought by geographic distance, temporal separation, and cultural diversity. Yet research regarding the impact of temporal separation and cultural differences is limited. This paper draws on an interpretive case study to examine the influence of culture on temporal separation and coordination of globally distributed software develop...
