Trend-Surface Mapping in Geographical Research

Research impact and scholars' geographical diversity

In recent years there has been a sharp increase in collaborations among scholars and there are studies on the effects of scientific collaboration on scholars’ performance. This study examines the hypothesis that geographically diverse scientific collaboration is associated with research impact. Here, the approach is differentiated from other studies by: (a) focusing on publications rather than ...

Temporal Maps and Temporal Geographical Information Systems (Review of Research)

The need to record the history of and the ability to reason about changes in the world has lead to a new field of research within the community of Geographical Information Systems (GIS). Recently a lot of new theory and concepts have emerged and a number of spatiotemporal data models have been presented. In this review we will have a closer look at the most important issues such as bitemporalit...

Geographical information systems: applications and limitations in oncology research.

The relationship between geography and cancer incidence and treatment is a critical area of health outcomes research. Geographical information systems (GIS) are software packages designed to store and analyze data related to geographic locations. Although more commonly associated with the social sciences and urban planning, the use of GIS software in medical research has been increasing. Moreov...

Analysis on Geographical Changes and Research on Spatio- Temporal Patterns

As efforts grow to develop spatio-temporal database systems and temporal geographic information systems that are capable of conveying how geographic phenomena change, it is urgent to analyze the impetus and mechanism that the spatio-temporal process happed. The authors proposed a set of universal change patterns for modelling of spatio-temporal processes, which builds a fundamental basis for th...

Integrating Research Data Management into Geographical Information Systems

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 ...
