Simple Thematic Mapping [PDF]

open access: yesThe Stata Journal: Promoting communications on statistics and Stata, 2004
Thematic maps illustrate the spatial distribution of one or more variables of interest within a given geographic unit. In a sense, a thematic map is the spatial analyst's equivalent to the scatterplot in nonspatial analysis. This paper presents the tmap package, a set of Stata programs designed to draw five kinds of thematic maps: choropleth ...

CARTE [PDF]

open access: yesProceedings of the 1st annual conference on Computer graphics and interactive techniques - SIGGRAPH '74, 1974
CARTE is the graphics display program of the LBL Computer Mapping System, producing thematic maps on microfilm at one hundredth the cost of producing negatives by hand. The program matches a geographical area with statistical data to produce graphic output on 35mm film in the form of cross-hatchedmaps for single-color printing or slides, or color ...
