Evidence of long-term woodland persistence despite prolonged anthropogenic stress
A multimillennial analysis of woodland ecosystems in the Leicestershire landscape (UK) shows significant anthropogenic stress over the last six millennia. We track these stresses using a combination of palynology and place-name evidence. We show a protracted period of deforestation from the Bronze Age (beginning ~4500 yr BP in Leicestershire), but the continuity of some woodland ecologies through to the present, with the managed re-establishment …
A mid-20th century stratigraphical Anthropocene is recognisable in the birth-area of the industrial revolution
The formalisation of the Anthropocene as a subdivision of the Geological Time Scale has been under debate. Its stratigraphic boundary has been proposed as a precise Global boundary Stratotype Section and Point (GSSP) in the mid-20th century, but it is part of an episode of human-induced changes to the Earth System that have unfolded over millennia. Here we attempt to identify stratigraphical patterns of the Anthropocene from a previously well stu…

Towards a study of everyday geographic information
Events are the driving force behind social media, whether we try to create them or keep up with them. A wide range of studies has focused on how content from social media can be used to detect, model and predict events and identify key topics of discussion. At the same time, very limited attention has been given so far to the quantitative study of the everyday, which has fascinated qualitative human geography research in the past few decades. Tha…
Digital geographies of everyday multiculturalism
As UK cities and towns become increasingly ethnically and culturally diverse, researchers have tuned into how people inhabit multiculturalism. Ethnographic approaches have focused on the kind of togetherness that people generate as they go about their everyday lives, observing the affective textures of interactions and happenings of the here and now in granular detail. Missing from these accounts is what crowdsourced data might add to understandi…
A graph-based semi-supervised approach to classification learning in digital geographies
Quantifying gendered participation in OpenStreetMap
This paper presents the results of an exploratory quantitative analysis of gendered contributions to the online mapping project OpenStreetMap (OSM), in which previous research has identified a strong male participation bias. On these grounds, theories of representation in volunteered geographic information (VGI) have argued that this kind of crowdsourced data fails to embody the geospatial interests of the wider community. The observed effects of…

OpenStreetMap data for alcohol research
There is a growing interest in using OpenStreetMap [OSM] data in health research. We evaluate the usefulness of OSM data for researching the spatial availability of alcohol, a field which has been hampered by data access difficulties. We find OSM data is about 50% complete, which appears adequate for replicating findings from other studies using alcohol licensing data. Further, we show how OSM quality metrics can be used to select areas with more…
Geodemographic biases in crowdsourced knowledge websites
Crowdsourced knowledge websites such as Wikipedia and OpenStreetMap are increasingly attracting a critical literature which has highlighted the fact that the contributor bases of these sites are often geodemographically biased: drawn from more affluent and better educated segments of the population. However, while bias in contributors is well known, we know less about whether this also results in a bias in outcomes on these websites: or whether t…
Codex
This article discusses a series of artworks named CODEX, produced by the authors as part of a collaborative research project between the Centre for Research in Education, Art and Media (CREAM), University of Westminster and the Oxford Internet Institute. Taking the form of experimental maps, large-scale installations and prints, the series shows how big data can be employed to reflect upon social phenomena through the formulation of critical, aes…
Towards a study of information geographies
Information has always had geography. It is from somewhere; about somewhere; it evolves and is transformed somewhere; it is mediated by networks, infrastructures, and technologies: all of which exist in physical, material places. These geographies of information about places matter because they shape how we are able to find and understand different parts of the world. Places invisible or discounted in representations are invisible in practice to …
Mapping information wealth and poverty
Gazetteers are dictionaries of geographic place-names that have important implications far beyond the worlds of geographers and cartographers. By containing 'definitive' lists of places, gazetteers have the ontological power to define what will and will not be geocoded and represented in databases, maps, search engines, and ultimately our spatial understandings of place. This paper focuses attention on GeoNames, which is the world's largest freel…
