The dasymetric map is a hybrid product combining the strengths and weaknesses of choropleth and isarithmic maps. [1]: 271 Dasymetric maps are used instead of choropleth maps because they represent underlying data distributions more accurately. Choropleth maps and dasymetric maps differ in three main ways.
A dasymetric map is an alternative to a choropleth map. As with a choropleth map, data are collected by enumeration units. But instead of mapping the data so that the region appears uniform, ancillary information is used to estimate a more detailed distribution of the phenomenon within each enumeration unit. For example, land cover data (forest ...
A Dasymetric map is a hybrid type that uses additional data sources to refine the boundaries of a choropleth map (especially through excluding uninhabited areas), thereby mitigating some of the sources of misinterpretation. A Proportional symbol map visualizes statistical data of point symbols, often circles, using the visual variable of size ...
Wright cautioned against the use of choropleth maps, instead espousing the virtues of the dasymetric map. Nine years later, in 1947, Wright introduced the notion of geosophy , `the study of geographical knowledge from any or all points of view.

Gott, Goldberg and Vanderbei’s double-sided disk map was designed to minimize all six types of map distortions. Not properly "a" map projection because it is on two surfaces instead of one, it consists of two hemispheric equidistant azimuthal projections back-to-back.
