Cartography
FMRI and Human Subjects Research in Cartography
In the past decade, the use of functional magnetic resonance imaging (fMRI) has grown, both in the number of studies published and in the number of disciplines finding application for functional brain research facilitated by this data-gathering method. A review of fMRI research in perceptual grouping and figure/ground and in visual search and attention is of interest in the effort to understand the human use of maps. These studies provide physiol…

Multimedia in Geography: Good, Bad, Ugly, or Cool
Technology has changed drastically in the last few decades and is profoundly affecting the way in which geography is recorded, studied, and communicated. One of the developments affecting the discipline is multimedia, the use of more than one medium—text, still graphics, sound, animation, video—to represent and convey information. Interactive multimedia gives the user control over the order in which to see or hear that information. In its current…
An Evaluation of Color Selections to Accommodate Map Users with Color-Vision Impairments
An experiment shows that maps can be designed to accommodate the approximately 4 percent of the population with red-green color-vision impairments. The experiment used seven pairs of maps with seven different color schemes to determine the effects of color selection on the map-reading ability of people with impaired or normal color vision. One rendition in each pair had colors that were potentially confusing to people with red-green impairments; …

Component-Color And Final-Color Separation In Mapping
There are two methods of pre-separating discrete (i.e., non-continuous) colors for printed color maps. In component-color separation an overlay is created for each percentage of each ink used in producing the image; in final-color separation an overlay is created for each color that appears on the final image regardless of how many inks and which percentages are used to produce it. Choice of separation method can greatly affect the ease with whic…

Spectrally Encoded Two-Variable Maps∗
The U.S. Census Bureau began publishing spectrally encoded two-variable choropleth maps in the early 1970s. Four experiments with human subjects have been conducted with these controversial maps to examine their efficacy. It has been shown that 1) subjects cannot spontaneously order the colors into the legend arrangement used on these maps, but they can recognize order in that arrangement; 2) the task of judging correlation between the geographic…

Autocorrelation and Visual Map Complexity
One important element in the overall look of a quantitative map is the relationship between neighboring values as they appear on the map, i.e., the autocorrelation in the map based on the classes into which the values fall. Methods of calculating this relationship objectively include rank autocorrelation; proportions of identical neighbors; average differences between neighboring values; number of clusters; and a weighted “proportion'’value which…
The Effects of Class Interval Systems on Choropleth Map Correlation
The correlation between a pair of distributions is often measured with the product-moment correlation coefficient, r. But the choropleth maps of the same distributions may be more alike or less alike than that coefficient would indicate. The degree to which map likeness corresponds to the correlation between the data before mapping is affected by the class interval method used. Using rank correlation (Kendall's t) to measure the map correlation a…
Class Interval Systems on Maps of Observed Correlated Distributions
The degree to which choropleth maps accurately reflect product-moment correlation between sets of data depends upon the statistical distributions of the data and the system by which they are divided into class intervals. Comparing results for observed distributions with earlier results for normal distributions, it is found that: (1) the expected values of rank correlations between maps (given the product-moment correlation between the data sets) …
