The University of Redlands has received a $25,000 grant from the National Endowment for the Humanities to support a workshop for GIS specialists and humanities scholars to develop methodologies toward visualizing the flow and movement of people and ideas across geographic space.
Diana Sinton, director of Spatial Curriculum and Research at the University, is the project director.
The NEH Digital Humanities start-up grant will support the workshop Visualizing Flow and Movement for the Humanities hosted by the University, likely in October, on this emerging research area at the intersection of digital humanities, geography and information technology.
Redlands’ proposal is supported by a 12-year history of infusing spatial thinking and geospatial tools across the campus and curriculum.
According to the proposal for the grant, there are no satisfying ways to visualize flow and movement of entities, such as people and ideas, across geographic space. Current tools and web programming allow researchers to create simple maps with lines connecting points, but the visual output is uninspiring and the usability is limited.
“Whether we study the flow of democratic ideas, the migration of early Christian monks to Africa, or the peregrinations of Native American ancestral sites, we are seeking to characterize the movement of entities through space and time,” the proposal said. The project will address questions on the nature and visualization of flow and movement to lay a foundation for developing a digital tool optimized for humanities scholars.

“Areal interpolation is used to transfer attribute information from the initial set of source units with known values to the target units with unknown values before subsequent spatial analysis can occur. The areal units with unknown attribute information can be either at a finer scale or misaligned with respect to the source data layer. This article presents and describes a geographically weighted regression (GWR) method for solving areal interpolation problems for nested areal units and misaligned areal units. Population data, selected as the attribute information, are interpolated from census tracts to block groups (a finer scale) and pseudo-tracts (misaligned from tracts but at the same approximate scale). Root mean square error, adjusted root mean square error, and mean absolute error are calculated to evaluate the performance of the interpolation methods. The land cover data derived from Landsat Thematic Mapper Satellite Imagery with a 3030 m spatial resolution are applied to as the ancillary data to describe the underlying distribution of population. To evaluate the utility of GWR as an areal interpolation method, the simple areal weighting method, a dasymetric method, and different ordinary least squares regression methods are used in this article as comparison methods. Results suggest that GWR is a better interpolator for the misaligned data problem than for the finer scale data problem. The latter is a result of issues associated with the scaling step to ensure the pycnophylatic property required in areal interpolation.”
From the charts of ancient mariners exploring new found lands to the age of Google Earth, maps are about far more than just navigation. They reflect the latest technologies, culture and the distribution of power and politics of their age.
The Map Reader provides, for the first time, a single source for the most important literature about the nature of mapping practices from the last hundred years. Fifty four theoretical and thought provoking texts demonstrate how cartography works as a powerful representational form and explores how different mapping practices have been conceptualised in particular social and historical contexts.
These original interpretative essays set the literature into context within the themes of politics, people, aesthetics and technology while drawing from leading scholars and researchers from across the academic spectrum including cartography, geography, anthropology, architecture, engineering, computer science and graphic design.
While the rhetorical power and technical complexity of how maps work has remained relatively under-analysed across the social sciences there has been a recent resurgence of mapping practices across the humanities, as well as in the information sciences, bio-informatics and human computer studies.
Written as a comprehensive guide to cover all of these disciplines The Map Reader ensures that the most important cartographic ideas are made available to researchers, students and cartography enthusiast alike.

From the Department of Geography, Planning & Recreation at Northern Arizona University comes a new blog about GeoDesign in higher education. The goal of Prof. Tom Paradis and Assistant Prof. Mark Manone is to encourage sharing of perspectives, experiences, and ideas related to GeoDesign in the curriculum.
GeoDesign in the Curriculum shares NAU’s experiences with their new GeoDesign-oriented curriculum for undergraduate majors, the Geographic Science and Community Planning Degree [PDF], which will officially launch in the Fall of 2011. Many of the curriculum materials pertaining to this new degree are found on the blog in the section titled The NAU Approach.

“Identifying drivers of deforestation in tropical biodiversity hotspots is critical to assess threats to particular ecosystems and species and proactively plan for conservation. We analyzed land cover change between 2002 and 2007 in the northern Andes, Choc, and Amazon forests of Colombia, the largest producer of coca leaf for the global cocaine market, to quantify the impact of this illicit crop on forest dynamics, evaluate the effectiveness of protected areas in this context, and determine the effects of eradication on deforestation. Landscape-level analyses of forest conversion revealed that proximity to new coca plots and a greater proportion of an area planted with coca increased the probability of forest loss in southern Colombia, even after accounting for other covariates and spatial autocorrelation. We also showed that protected areas successfully reduced forest conversion in coca-growing regions. Neither eradication nor coca cultivation predicted deforestation rates across municipalities. Instead, the presence of new coca cultivation was an indicator of municipalities, where increasing population led to higher deforestation rates. We hypothesize that poor rural development underlies the relationship between population density and deforestation in coca-growing areas. Conservation in Colombia’s vast forest frontier, which overlaps with its coca frontier, requires a mix of protected areas and strategic rural development to succeed.”
