Gridmappr
We present gridmappr , an R package that automates the process of generating gridmaps – small multiple data graphics of regular size, laid out with an approximate geographic arrangement. Given a set of real geographic point locations, gridmappr allocates points to a regularly sized grid of stated row–column dimensions. This allocation is constrained such that the distance between points in real and grid space is minimised and with a parameter tha…
Mapping ‘sluggish’ migration
Emigration is a major theme in Ireland’s demographic history and has, as a result, received significant attention in scholarship. By contrast, the less prominent story of internal migration has been much less researched. This has resulted in a neglect of the changing geographies of those who remained in Ireland. Here we use Origin-Destination (OD) and Destination-Origin (DO) maps to explore changing patterns of internal migration in Ireland from …

Describing place through user generated content
Geographically referenced user generated content provides us with an opportunity to, for the first time, gather perspectives on place over large areas by exploring how very many people describe information. We present a framework for analysing large collections of user generated content. This involves classification of descriptive terms attached by users to photographs into facets of elements, qualities, and activities. We apply this framework to…
Visualizing the Dynamics of London's Bicycle-Hire Scheme
Visualizing flows between origins and destinations can be straightforward when dealing with small numbers of journeys or simple geographies. Lines embedded in geographic space have commonly been used in mapping transport flows, especially when geographic patterns are important, as they are when characterizing cities or managing transportation. For larger numbers of flows, however, this approach requires careful design to avoid problems of occlusi…
Treemap Cartography for showing Spatial and Temporal Traffic Patterns
Please click here to download the map associated with this article. Depicting spatial and temporal aspects of traffic flows of different types is challenging. We use a treemapbased technique that is able to show multiple aspects of large quantities of spatial and temporal traffic data simultaneously. Treemaps present multivariate data as a hierarchy of rectangles that are nested within each other. Each level of the hierarchy is used to carry info…
Rectangular Hierarchical Cartograms for Socio-Economic Data
Please click here to download the map associated with this article. We present rectangular hierarchical cartograms for mapping socio-economic data. These density-normalising cartograms size spatial units by population, increasing the ease with which data for densely populated areas can be visually resolved compared to more conventional cartographic projections. Their hierarchical nature enables the study of spatial granularity in spatial hierarch…
Where is Helvellyn? Fuzziness of multi‐scale landscape morphometry
The landscape in which people live is made up of many features, which are named and have importance for cultural reasons. Prominent among these are the naming of upland features such as mountains, but mountains are an enigmatic phenomenon which do not bear precise and repeatable definition. They have a vague spatial extent, and recent research has modelled such classes as spatial fuzzy sets. We take a specifically multi‐resolution approach to the…
Geospatial Information Visualization User Interface Issues
User interfaces for geospatial information are the tools by which users interact with and explore that information. The provision of appropriate interface tools for exploiting the potential of contemporary geospatial visualization products is essential if they are to be used efficiently and effectively. This paper addresses issues and challenges in interface development and usage that are identified as paramount within the geospatial visualizatio…
Evaluating the Perception of Uncertainty in Alternative Visualization Strategies
Although a number of methods have been proposed for representing uncertainty in spatial information, there has been relatively little testing of how users interpret uncertainty from those methods. Using results of a fuzzy classification of satellite imagery, this study looks at users’ perceptions of a number of different methods for visualization of uncertainty. Both relatively expert and novice users are highly successful at determining classifi…
