Value-by-alpha maps: An alternative technique to the cartogram.

Cartogr J 2010 May;47(2):130-140

GeoVISTA Center, Penn State University, 302 Walker Building, University Park, PA 16802.

The cartogram, or value-by-area map, is a popular technique for cartographically representing social data. Such maps visually equalize a basemap prior to mapping a social variable by adjusting the size of each enumeration unit by a second, related variable. However, to scale the basemap units according to an equalizing variable, cartograms must distort the shape and/or topology of the original geography. Read More

Resolution Control for Balancing Overview + Detail in Spatial, Multivariate Analysis.

Cartogr J 2008 Nov;45(4):261-273

GeoVISTA Center and Department of Geography, Pennsylvania State University, 302 Walker Building, University Park, PA16802, ,

Parallel coordinates, re-orderable matrices, and dendrograms are widely used for visual exploration of multivariate data. This research proposes an approach to systematically integrate the methods in a complementary manner for supporting multi-resolution visual data analysis with an enhanced overview+detail exploratory strategy. The paper focuses on three topics: (1) dynamic control across resolutions at which data are explored; (2) coordination and color mapping among the views; and (3) enhanced features of each view designed for the overview+detail exploratory tasks.
